Why Replacing Injectors May Only Be a “Band aid” Fix
Knight’s Toyota dealership had a 2007 Hilux arrive with a bad and unmistakable rattle, and all the injectors scored off scale readings. The engine was shaking, rattling and knocking a lot, indicating a costly replacement of at least $4000 for new injectors.
The owners were offered CRD diesel fuel additive instead of paying for costly replacements. Using this effective product saw the Hilux injectors testing “as new ” and performing soundly. In this case, the injectors were actually fine, and the root cause was restored by using a diesel fuel additive returning full cleanliness to the injectors. It also worked by providing necessary lubricity to better cope with the high temperature, high pressure, and fine tolerances of the common rail system.
Like all automotive systems there’s no lack of horror stories about problems with common rail diesel engines. Our fuel system cleaner is the real- life FIX for most common rail issues and adds life to your system. Benefits include:
- Cleans the entire CRD fuel system
- Concentrated injector cleaner
- Boosts diesel lubricity
- Anti-corrosion protection
- Restores power & economy
- Complete treatment
- 250ml treats 2000L of diesel
Using this product will help you save between $ 1500 to $20 000 in replacement parts to ensure everything is running smoothly long-term.
Try Our System Cleaner Additive Before You Rebuild
By using our system cleaner additive, you can:
- Prevent, eliminate, or minimize noisy injector rattle from your CRD engine caused by noisy valve tappets.
- The injector could be fouled by contaminant or is seizing due to inadequate lubrication. Excessive fueling would likely be causing detonation inside the combustion chamber, instead of smooth combustion.
- Clean the pump & injector deposits and disperses contaminants as they form.
- Boost lubricity.
- Provide exceptional anti-rust protection to pumps and injectors
Is your fuel consumption going through the roof, or is your vehicle performance suffering? Save anywhere between $2000 to $20,000 on replacement parts and motor repairs by using our additive.
CRD Injectors and pumps are expensive, run incredibly fine tolerances, and are highly stressed due to enormous pressures and high temperatures. Compared to older technology diesel fuel systems, they are totally unforgiving of any contamination. Small amounts of water or contamination will wreck pumps and injectors and are generally non-repairable, meaning replacement components are required.
The damage doesn’t always stop with injectors and pumps, another common problem includes sticking injectors resulting in melted pistons. Costing around $10,000 to $20,000 for replacement. Compared to the cost of our treatment were saving you a considerable amount of money with less interruptions in using your vehicle.
CRD engines have been developed to meet the latest emission standards, and diesel fuel sulphur is now very low for the same reason. However low sulphur fuel happens to compound another problem, lubricity! Pumps and injectors rely on diesel fuel for lubrication and with its reduction, they must get the proper treatment.

CRD Fuel Enhancer for Common Rail Engines
Instructions: How to clean and maintain diesel injectors
Add to diesel fuel at 10mL per 80L
CRD Fuel Enhancer can be double dosed when:
- Injector feedback values are out of spec
- Badly worn injectors with a severe injector rattle
- Bad diesel fuel has affected vehicle performance
Common Rail technology was introduced to diesels in 2007, and these will require CRD Fuel Enhancer. It can be used in earlier diesel engines, but is not suitable for petrol engines.
The Common Rail Diesel (CRD) injection system is the most recent development to achieve ever more stringent diesel exhaust emission standards, but it is currently associated with widespread problems, including engine rattles, expensive injector and fuel pump failures, injector sticking, stalling problems and rapid piston and liner wear. Problems have been documented across a wide range of engine suppliers, including Toyota, BMW, Volkswagen, Nissan and many more.
Cost Effective Maintenance have specifically developed our fuel additive ‘CRD Fuel Enhancer’, to address rattles, and provide smooth operation of fuel pumps and injectors. Used routinely, it will increase the service life of fuel systems and minimize the potential for the above problems.
The CRD system requires a significant increase in operating pressure compared to earlier systems. Fuel system pressures of up to (and above) 30,000 psi are required, and combined with ultrafine tolerances of diesel pumps and injectors, achieve superior fuel atomization for cleaner combustion. There are several factors that place significant additional stress on this system, compared to earlier diesel injection systems…
- The increased operating pressure causes higher loadings on equipment, and this places a bigger demand on the fuel’s lubricating ability.
- The higher pressure causes much higher fuel temperatures, which can actually degrade the fuel, forming fouling deposits within pumps and injectors. Such deposits interfere with the fine tolerances, to cause sticking, malfunction and injector wear. This risk increases if using biodiesel blends, since biodiesel by nature, degrades faster.
- Diesel sulphur levels have been reduced, to reduce smoke emissions. However, sulphur provides lubrication, so lowering sulphur levels can result in greater wear to very expensive fuel pumps and injectors.
- CRD engines are designed with much finer tolerances within pumps and injectors, as well as piston to liner clearances, making them much more susceptible to deposits, and also the presence of any water contamination in the fuel.
CRD Fuel Enhancer provides strongly enhanced fuel lubricity, superior deposit control for fuel pumps and injectors, and exceptional anti-rust/anti-corrosion protection. While it’s recommended as a routine preventative step for CRD engines, it has been shown to eliminate severe injector rattle, restore operating performance and economy. It is designed specifically for Common Rail Diesels, but is suitable for all diesel engines. It is not recommended for petrol engines.
Many Common Rail Diesels are also prone to building high levels of soot in the oil. For this reason, we also recommend using the Flushing Oil Concentrate. Look for the CRD Fuel Enhancer/Flushing Oil Concentrate Special (CRD/FOC) fuel treatment package for a full system clean

Hilux uses CRD from new .
Hey gents, just wanted to say thanks for a great product. I’ve just done 10,000 clicks on my Hilux and used your product from the start. No rattles at all unlike my mates that doesn’t use anything. Currently at Moreton Island from Melbourne amazing place so much fun. Good to know I can rely on my motor staying clean and working at its best. Thanks Gasso
CRD saves Prado TD with petrol in diesel
Report from Knight’s Toyota (Tristan) Their customer had purchased a new Prado TD and were travelling. After a 240km drive the Prado stopped and wouldn’t restart.
It was subsequently delivered by tilt tray to Knight’s Toyota (Leongatha VIC), where they were told that the owner had accidentally refuelled the Prado with 130L of petrol prior to driving the 240km. Service manager, Tristan Wilson advised the owner to expect a very costly rebuild as it was almost inevitable that a new fuel pump and injectors would be required.
While Knight’s had a lot of success rectifying injector problems with Cost Effective Maintenance’s CRD Fuel Enhancer, they didn’t expect it could save this engine. However, they decided to give it a go.
After draining the contaminated fuel, a strong dose of CRD Fuel Enhancer was added to 20L of diesel, and the fuel system bled. To their surprise, the engine started and within 5 minutes of rough running it cleared. A diagnostic check indicated that everything was OK, and the vehicle was test driven and then returned to a rather happy owner. Follow up communication with the owner confirmed that the engine was performing perfectly.
This kind of personal service from the Team at Knights Toyota is outstanding !
2012 Colorado 4×4 dual cab gets petrol in the diesel
This customer was using CRD Fuel Enhancer in the diesel of his Colorado. He was running low on fuel so put $20 in till he got to his usual servo to fill up. It ran a bit rough after a while & he thought he might have got some water in the fuel, so checked the filter drain & all clean. He put in some more CRD Fuel Enhancer as extra lubrication & protection against rust.
It seemed “OK”sh at highway speed so drove the 80km home. But into local traffic it struggled to get any revs above idle!
So next morning it was tray topped to the Holden dealer, who soon reported that there was petrol in the diesel, and that Colorado fuel pumps don’t handle petrol or water and it will need to be replaced. But when the job was complete, there was some good news…they couldn’t fault the pump or injectors. The system had all been cleaned out and was ready to pick up!
Knight’s Toyota, Leongatha (VIC)
Hi Brid, i have attached the dyno sheet of the Hilux you have mentioned in the add. This dyno run was done after the vehicle had done a run to Cape York with your CRD additive. Before it had left for Cape York all injector feedback values were off the scale, all reading –5 to +5 (these should be around –1 to +1 to be in spec). It was rattling, shaking and knocking alot. We sent the customer on his way with your product and trust of it to take the vehicle to Cape York without causing any damage.
Once the vehicle returned, these feedbacks on all injectors were around –0.5 to +0.8. Customer couldn’t believe the results. Whilst here for the service, we put the vehicle on the dyno before and after, after using your FOC and AW10 you can see the broad increase in torque and power right through the rev range. This vehicle was still using your CRD at the time it was on the dyno. From experience, with brand new Hilux’s we have put on the dyno for comparison, these vehicles are only making 70 to 85 RWKW. So the results of your product on a car that has done 160,000km is absolutely outstanding (105.4RWKW, we have never seen a stock Hilux make this much power!). I look forward to using your product on more vehicles in the future and keeping you updated with dyno results to prove your products. Thankyou
Tristan Wilson, KNIGHTS TOYOTA (Leongatha VIC)
Komatsu PC15-2 excavator…Toughest test yet for CRD Fuel Enhancer!
I have a worn out, old excavator that I bought for at-home landscaping. It might get used 1 or 2 times a year. Recently I did a small job, and just before I parked it up the revs were fading. I thought I ran it out of fuel. So 3 weeks later I thought I should refuel it and bleed the system. But then I noticed the fuel filter was full of water. It was through the fuel pump and injectors…it didn’t run out of fuel at all.
It hadn’t been refuelled for about 4 years, which had FTC Decarbonizer and Cleanpower in it, but it had built condensation. The pump pistons seemed to be seizing. I could only get a bit of water and rusty stain out in dribbles. My only change of recovering it to running state was to free up the pump, so I put CRD in the fuel tank and a strong hit in the fuel filter. I could only bleed a small amount through the pump, so I did a bit each day, by cranking it over a few times, then leaving it to soak over night. After a week of this, I reconnected the fuel lines and she fired up and sounds just as good as before.
D4D Hilux Ute
Paul Burgess purchased CRD Fuel Enhancer for his Hilux (70,000km) for preventative reasons, as he did not have any issues with it. He tows a camper trailer, and will normally sit on 100kph where possible. He recorded these fuel consumption figures while towing.
Tank before using CRD…15.3L/100k
1St Tank with CRD…14.2L/100k
Paul consider both to be similar driving conditions, and didn’t expect to see such an improvement of this size.
2005 R51 Nissan Pathfinder 2.5 litre Turbo Diesel
Hi Guys, I have been using your products since discovering them in 4WD Action Magazine a couple of months ago. I drive loaded with a steel roof rack, bull bar, winch, drawers, fridge, etc, etc. It has 235,000 km on the clock, and sees its fair share of bush work.
I’ve always had a rattle in the morning, and I know it’s a sticky injector. I’ve poured all sorts of crap into that fuel tank, from “injector cleaner”, to 2 stroke oil, with no change. I tried your CRD Fuel Enhancer, thinking, “here goes, more money down the drain.” Well, wasn’t I amazed when the Pathy started running quieter, smoother and more economically, from about 150 km from the first dose. I even gave some to my mate across the road to try in his very rattly 2.8 ltr GU Patrol. We both agree, both engines are quieter and smoother.
Next, I tried the Decarboniser. I’m still within the first 20 hours, but already I have noticed a difference in smoke output and general performance.
Yesterday is where I became disappointed. I got some of your Flushing OIl Concentrate, and following the instructions to the letter, changed my oil. Today, I drove the usual 115 km to work, from Melton to Beaufort. Usually within this time, my oil would be the usual thick black. When I got to work, I thought I’d check the oil, feeling sure it would be black as usual. I pulled out the dipstick, and sure enough, I nearly had a heart attack. The dipstick had no oil on it!! I then had another look. I realised the dipstick had the correct amount of Penrite’s finest on it, but it was so clean I couldn’t see it.
Why am I disappointed? For years, I’ve tried different brands of fuel and oil treatments that claim to do magical things, but never live up to the promise. I could probably buy a new car with the money I’ve wasted. Finally, a product that does exactly what it claims to do. Each and every one of your products that I have tried so far has done exactly what it says it will do. Thank you for bringing these products to us. I will certainly do my best to spread the word.
Thanks Guys
Sean Murphy.
Comments from Pajero Forum…
“Go to www.costeffective.com.au site. Brid Walker has been giving me the heads up and selling me various products for 25 years. He has a CRD additive available now on the net. Get to his site and have a read I would not drive my paj without CRD. I recently took the EGR system off the NT DID, and the intake manifold to clean it out. It was spotless. I also use their sludge cleaner once a year and the inside of the motor is spotless. The oil that is put in after a sludge clean is still clear a fortnight later”…Ben

Has quietened the injectors in 2 tanks
Jim –
On my 4th tank of fuel now, I haven’t noticed any difference in engine noise, fuel consumption, dpf activation, nothing, I haven’t given up, still have plenty left for a few more tanks of fuel. 2017 Hilux.
Ethan –
The injectors on my 07 4JJ1 Rodeo have been getting a bit long in the tooth by now at 320,000km’s, with one injector knocking noticably when idle after it’s been for a drive and warmed up. I haven’t found CRD fuel enhancer to provide any improvement in this regard or when driving, and I don’t believe it’s a magic fix for old flogged injectors like much of the other reviews seem to portray. Worth a shot, but I’m still likely up for a big injector replacement $$
Ross Clery –
Prompt delivery, great product
David Kellett –
I have just started using FTC diesel decarbonizer along with CRD fuel enhancer and have already seen an improvement after half a tank. The smoke out the exhaust has nearly completely gone, the injector rattle has decreased and the engine runs smoother already.
Honestly, I was embarrassed to drive my 2011 Nissan D40 as the smoke was terrible.
Robert Williams –
Fast post and good product
Bruce –
I have given a 5 star because any shortcomings are beyond my knowledge. Have been dosing my fuel with this stuff for 20k and don’t really know what difference it is making. Probably just a bit insensitive to minor/medium changes to the way my troopy sounds/runs/feels. If it was a motorcycle fuel additive I could give an informed opinion.
Greg Purcell –
It has bought my injectors back to hood and my fuel economy has improved
Highly recommend
chris snell –
read about this and saw the reveiws and thought why not use this in my pajero hopefully it will hep the injectors

2008 Toyota Hiace Commuter, 4 pot Diesel manual, used as tradie van. 386K on the dial.
Used in combo with DPF cleaner, first tank made this oversized white whale turn into an flippen Orca again.
That thing others call “acceleration” came back, take off torque from the lights even made a welcome return.
The engine is running smoothly and quieter on start up…..
And this is all.on the first tank.

It’s a great product I see improvement in my Grand Cherokee Diesel performance, thanks
Kenneth Oertle –
I noticed a reduction in smoke emissions and quieter engine running after a week of using this product. Highly recommend this product.
Ted Dekker –
I am really surprised and impressed with the CRD Diesel Fuel Enhancer. 👍
I bought it because my injectors were getting too rattley since they are due for replacement. Unfortunately this costs several thousand dollars, which we as pensioners need to save up for.
Because I was so very worried about the state of my injectors I bought this as a hopeful stop-gap before replacement.
WOW the difference is really noticeable, the rattle with the cold engine has dramatically reduced and I’ve only gone through approx 45 litres of diesel with the CRD Fuel Additive in.
I will still replace the injectors as soon as we can, the D4D 3.0L 1KD-FTV Toyota Prado 120 engine has done some 270,000km on the original injectors, and I’m advised it’s about time for new ones.
After which I will add the 10ml per 80 litres of fuel every few fills, just to keep the new injectors clean 😊
Thank you Cost Effective Maintenance people for a product that really works !
I can sincerely recommend this product,

Been using on my 2012 Pajero for the last 30,000km with engine running smoothly, last 3 tanks filled with no CRD enhancer and experienced slow/ rough idle on start up on cold mornings, Filled up and used enhancer again very next morning and normal start and idle… Purchasing larger bottle for the Missos MUX and my Paj right now.

Bradley Ronald Webb –
I added 15 mls to my long range tank 2014 3 litre dmax 250 000 ks but only travelled 300 km to date . In that short distance I noticed the engine is much quieter and appears to run smoother I will definitely be using this product on a regular basis.
Kevin Jones –
Good product great results so far 👍
Chris Falcon –
👍👍👍👍👍👍👍👍👍👍👍👍
Jeff Bryant –
This is a fantastic product that everyone with a diesel engine should use from new. I have been using it for 12 yrs in V8 70 series & 2.8 Fortuner & now Landcruiser 2.8 engines.
The Fortuners were used on short trips but have not had any DPF issues or fuel problems. The same applies to trips over the Simpson desert & to the Kimberlys in the V8’s.
I also get great fuel economy the Fortuner as low as 6.8L per 100k & the 2.8 Landcruiser 8.9L per 100k & I am sure the fuel enhancer has something to do with achieving these figures.
Shane –
Great product car seems to be running smoother

Great value for money and customer service is fantastic
Brid Walker –
Hi Glenn, the CRD is suitable for Ford Rangers. Keeping the injector spray pattern accurate will help avoid some of the problems the rangers have.
Glenn –
I didn’t see anything about ford rangers does it not work for them
steven bailey –
My Ranger PX2 started the death rattle I did a double hit with fresh fuel an after 100km it has stoped still have 900km in fuel so will only get better I would say.
A cold starting has improved.
This is a great product heaps better then the off the repco – super cheap stores
Darryl Porteous –
Sorry I have not used this product long enough to comment.
Darren Webb –
Fantastic product.
Quietened down my 280,000km old injectors in my 2016 ranger.
Weren’t too noisy but certainly quieter now after a double dose then single dose.
Bryce Langman –
Injector noise has drastically reduced, feels a little more responsive to Throttle imputs
Mark Gimbrere –
Great product, seems to make a noticeable difference
Jonathan Day –
Got back some performance and fixed an idling issue
A & S Davis –
Experienced serious injector rattle onset with our 2012 D-Max when returning home from a family visit in Far North Queensland in 2021. Our service provider, Damian, at YURI in Toowoomba suggested we try CRD Fuel Enhancer ….. problem solved on the initial dose so have been using it ever since. Definitely a cost effective solution with the added bonus of on-going preventive maintenance. Also, because the D-Max is being used predominantly as an urban vehicle, I am also using the FTC Decarbonizer for added protection. I have no hesitation in recommending these products whenever I get the opportunity.
Daniel Cochrane –
Never had a fuel drama since using
Mick Kime –
Great value for money and it works
John finnigan –

Great product. This is my second purchase.

Great product
L M –
I have noticed fuel economy drops when getting close to a service. Since using this product I have noticed an improvement with engine noise / smoother idle and responsive throttle response.
Also, noticed fuel economy back to normal. I am using this product as a preventative and ongoing healthy maintenance addition for my cars engine. I highly recommend this product.
IanPink –
Added this to my fuel two tanks ago noticed a change straight away quieter and smoother running and using three litres per 100 ks less diesel great stuff
Greg Purcell –
My fuel economy wasn’t great and I felt I didn’t have the power while towing my 3.5 ton caravan
Was told to change out injectors my 200 series cruiser has 8
A big cost
A friend told me to try this product
So I did wow what a change fuel economy is back and so is my power while towing
Very happy will continue to use this product 👍
Trent –
So far so good,can’t wait till I use the decarboniser
Jason Fisher –
CRD fuel enhancer, Great product, have used for few years now, 2017 ford Ranger, highly recommend

Jacob Thomas –
Nice fast postage, the product works well it a must have for me
customer –
This is an amazing product! My Triton MR series developed serious injector clatter and was ” hunting” at any constant throttle position after a trip from Brisbane to Perth through the Nullarbor. I was told to replace the injectors, but a friend suggested that I tried Cost Effective Maintenance’s CRD Fuel Enhancer and FTC Diesel Decarbonizer. After four full tanks of treated diesel, my Triton sounded and ran like new. I now treat every tank of diesel with the maintenance dosage of both the CRD Fuel Enhancer and FTC Diesel Decarbonizer. It is worthwhile noting that it works out substantially cheaper to buy both the CRD and FTC additives in larger volume packaging. I buy the FTC Decarbonizer in 5 litre size and the CRD Fuel enhancer in 1 litre size.
Jason –
Prior to using this product my vehicle was relatively smoky and had a rattle under acceleration but since the rattle has all back gone and the vehicle is blowing less smoke and Less I’m absolutely burying my foot to the floor. Using a small amount this product really goes a long way and lasted me at least six months for the one bottle very well worth the money
Gary Moore –
Used it for years keeps diesel motor purring
Colin Gelder –
Had a slight miss in the engine when idling so started adding this. Soon after idling was a lot smoother. Very happy

Smoother, quieter running with some improvement in fuel economy.
Highly recommend.
Keith Heinrich –
Noisy idle was much less on the first tank of fuel and the car runs much better as well. Fuel consumption is noticeably better since using the product. I’ll continue to use this product.
Vic Bulman –
Great product .
Lisa –
This product was recommended by the seller of the vehicle my son purchased, and he has used it ever since -(4 years now). The car is an older 4×4 and my son believes that this product has played a big part in the performance of the vehicle.
DAVID –
On my second bottle of this I firstly bought a small bottle to test it kin my 2007 Hilux SR5 260000 km, no injector change. I run out of that and bought a second bottle – very good stuff, would use it again and look at the other products available. I need to look for a product that will clean the Toyota Hilux EGR
Edit: before the first bottle I was getting around 589 km a tank, on the first bottle complete it was around 605km today when I filled it up the ute was on 616km per tank
Highly recommended

Mike K –
200000 km still running perfectly on original injectors.
Greg Worthington –
Service good, decarboniser first time used too early to tell. Fuel enhancer great easy dispenser effective

Ben –
I was amazed at how fast and well this worked, had injector issues fairly early on a newer vehicle due to a poor fueling issue, rectified the problem then added the additive and I haven’t looked back
Brett Parks –
Used on my wife’s 4WD. After 1000kms we’re seeing power and fuel economy improvements.
Robert Wood –
Good product to deal with various diesel qualities as we travel around Australia
Wayne Evans –
Haven’t felt any change in performance yet it maybe a little quieter in running. This is in ford Everest 2015.
itIs only the first tank full nearing 600km so maybe after the first tank I’ll see some change.

Excellent product that works

Sid Gurler –
Absolutely amazing product
Bruce Gilpin –
Iy has fixed my problem with dripping injector or injectors.
Mal –
Obviously cleaning the system – no more black smoke under harsh acceleration!!
Phil Pearce –
I’ve always been a sceptic when it comes to fuel additives as it’s pretty hard to actually measure any results and then this comes along.
I’ve now been using CRD in my Pajero for 130k klm since it was near new and the engine is still returning excellent economy whilst towing and my catch can isn’t collecting much in the way of blowby (about 30ml per 10000k).
We are making zero smoke, even under heavy load, and the engine is smooth.
This product is well worth the money.
Andy Nicholls –
It’s a great product. Using in a 2013 Chrysler 300c diesel.
It only took a week to start seeing positive results.
Going to check out the engine flush.
Phil –
I’ve been using this product since my Pajero was near new. The car is used almost exclusively for towing so it gets quite a workout. It’s normally difficult to be able to gauge whether a fuel additive is actually doing anything except in this case, my mechanic often mentions the lack of oil product in, and the cleanliness of my catch can. Between services, there’d never be more than 30-40 ml of oil to dispose of. I haven’t had to replace the catch can filter in 150k klm. This product works well and is very cost effective.
Aaron –
Awesome product
customer –
Product seems good, of course it’s hard to tell what would have happened if I didn’t use it!
Duane Rangitauira –
This product is awesome , cleans the injectors quiets the diesel rattle so good and more then value for money when compared to having to get new injectors for your vehicle , absolute no brainer . Massive thumbs up from me .
Clayton OBrien –
Great products, have noticed a substantial difference in my diesel since I’ve been using three different products. Should also mention the stupidly fast delivery and great customer service and support.

Rick Shammall –
Works great, definitely better than anything I’ve used before
Al Anderson –
The new bottle with the long neck is much better for pouring.

This product does what is says it does made huge difference to my 2.5 litre turbo diesel just after 2 tanks fulls of diesel will definitely buy this again.
John Morrison –
Been using this product for a while and won’t use any other brand, my opinion, this product works wonders, I have used it in 2 of my vehicles and will continue to use it.
John Ninness –

Liam deering –
Absolutely loved this, helped clear up first try
Dave –
I’ve been using it now for about 2 years in my 2015 200 Series and found it extremely good, no more soot, quieter running, better fuel economy and for the price and the small amount you use it’s well worth it.
Rodney Duncan r –
So far I can notice the difference in how the engine has quietened down dramatically thanks for quickness of supply of your product
Jason Dawes –
My Nav was not running to healthy even when BP claim to have something in diesel to help clean n fix , but no it don’t work, on the other hand your stuff is awesome, Nav running great now after one mix in full tank , totally recommend.
Luke Buse –
Excellent service from this company waiting to see if the product dies what it says !!
Greg Farlow –
Does exactly what it says, been using for a long time, never had an injection issue
Mick Tuttlebee –
Simple efficient effective. Injectors are at 270k k’s will easily see the car out in 10 years time without changing the injectors. Started using at 230k k’s.
Trevor Thorne –
Got it for my sprinter van , noticed a big difference, runs better idle and starts better fuel economy has come down so will keep using it ,van done 450,000 km great stuff going to try the engine cleaner next ,

dave warrell (wonks_floss) –
Great product been using for years. Excellent service.
Luke Blanch –
Best additives made by far couldn’t recommend high enough the guysbare also all over the product
Phil Sims –
This stuff is the goods. Put in my 2l Amarok (tune + exhaust) and within 2 tanks, it cold starts easier, runs smoother, and the cold rattle has basically gone.
It used to have a bit of a hesitation/surge issue climbing long highway hills on cruise control, replaced fuel filters which didnt fix it, this stuff did.
10/10 would recommend.
Mick Hawdon –
Been using it for the last 10 years in my 79 series Landcruiser wouldn’t use anything else.
Roger Lane –
I have an older 2005 SsangYong Rexton .
Only been using for a short time but noticed an increase in performance.
steve Hammersley –
only downside was the delivery from aramex which i know is out if your control, del was thursday didnt arrive untill monday.
the other little thing i dont like is the bottle. if only needing 10ml, per 80l which is the majority if vehicles, why is the small dispenser so large, very easy to overfill and no way to reduce other than to pour out. could be made to hold max 15ml.
Quinton Jacobs –
Use the CRD for 3 years now on 79 series v8 Land cruiser with noisy injectors, which did improve start up, reduce smoke, noice and have better performance. Product is definitely saving me a set of new injectors.
Bruce Cartwright –
Haven’t used this particular product before, now using it in my 2015 VW Golf TDI, had previously used Clean Power in my old Patrol which was DI, HAVE EVERY CONFIDENCE THIS WILL BE AS GOOD.
Paul E –
After using for 2500km I’ve noticed a reduction in injector noise with my Prado 150 diesel.
Bill O’Reilly-Smith –
Good price, good product.
Chris Robinson –
I’m surprised – it absolutly works. Mercedes Benz ML 2006 320 Diesel 16 years old – reduced the rattle – goes better – no black puff on open throtle. Well worth the money.
Thanks
Steve Cork –
nothing to say, it speaks for itself
John Klowss –
Great product
Luke Poretti –
The product is excellent, my 79 series goes much better.

It works like it says it does
Bob –
Good product works well
Alex Doidge –
This stuff is amazing. I used a injector cleaner from an automotive store and my 2009 hilux started to run terrible. Blowing smoke on startup, low idle to the point of almost stalling, loss of power.I messaged the customer service at cost effective maintenance and told him my problems and he recommended I try this as it’s especially for Diesels (he was super helpful and informative) . It arrived a day or two after I ordered (NZ) Put the recommended dose for a full tank into my quarter tank, went straight down to the gas station and filled up. Went for an hour drive and bam… Problem solved. Running great. Highly recommended! Great price for how many doses you get from one bottle too! Happy customer
Des Seres –
Fast delivery
Craig Hillier –
A great product for a reasonable price
Alex Doidge –
Brought the CRD Fuel enhancer after having low and irregular idle on startup, blowing smoke and loss of power, done a service, changed fuel filter with no change.. was starting to think injectors were stuffed. Added recommended dose. Filled the tank and took my truck for an hour drive. Next start up, she was running beautifully. No smoke, no rough idle was good as new!! The stuff is great. Low cost, good product! Recommend to all!
Nigel Blackhurst –
Stopped blowing smoke in 2 days 😁

I bought CRD Fuel Enhancer, AW10 Antiwear, and Flushing Oil Concentrate
if the Enhancer and Antiwear or half as good as the flushing oil I’ll be happy

Love it. I have noticed improvements in the engine and fuel economy. Not to mention less smoke under excelaration
Frank Latty –
Too early to tell as only 400kms since adding to fuel, so star rating is not applicable. Slight improvement in fuel use at high speed none stop use. City driving shows no difference. Early days
Kevin & Rachel –
I have used this product in my last 4×4 had six years did 245000 kms and never replaced the injectors using it my new 4×4 also my brother in law using it in his 4×4
Christopher Tuason –

Mark –
I will continue to use this product while I drive a diesel. It will keep your diesel fuel system/ injectors in great condition and will reduce noise…Friends have used and are surprised. You”ll buy a cartoon of beer for yourself ,buy some CRD for your diesel it will repay you 10 fold😆😆
Wayne Love –
Awesome product & will definitely be buying this product again & recommend to a lot of my mates….

I purchased the crd fuel enhancer for noisy diesel injectors, it took a couple double doses at the start but it has definitely taken the knocking away. I will continue to use this product for as long as I have a diesel vehicle.
James Gifford –
Decent product. Early days for any real results.
Rodney Hicks –
Easy to use and effective
Damion W –
From the first time I used the product on my Audi Q5 2018 3.0 Tdi, from the fuel station I could notice a sheer power difference in acceleration and smoothness and fuel economy has come down to 6.4 on the motorway going to Victoria.
William Robinson –
Absolutely excellent product
Nev Cunning –
Haven’t used yet .

Chris Ryan –
I have a 2012 Kia Sorento with loud injector noise, did a double dose on a full tank of premium diesel and a 1/4 of a tank in have noticed a decrease in the injector noise. Can’t wait until it’s had a couple of doses to see if it improves any more.
Darcy –
Still on the first tank after adding this stuff at a double dose and haven’t noticed any difference and don’t expect to as I bought it as a preventative maintenance item.
Given the cost of a bottle, how much you use and how long it will last me I figured it’s worth using.
More than enough people recommend it and if old Roothy uses it along with other items Cost Effective offer then it’s good enough for me!
Rod Wallace –
I have a Patrol with a ZD30 in it. It has 300k on it and it was idling roughly and using more fuel than it should.
I have just put the second tank of dosed fuel through it and it already idles more smoothly and quieter. Also fuel economy has improved slightly.
Daryl Ryan –
Easy to use product for injector cleaning
David Attard –
Got this for my 2011 amarok. Since I’ve had it it’s always sounded rough. Most likely injectors or valves. After one treatment engine was significantly quieter and idling smoother. Highly recommend.
John Milsom –
Very good product, I’m on my 3rd take with this additive, & I can honestly say I can notice the difference, my fuel consumption has improved & my 200 series seems to be a lot smoother under heavier acceleration.
Gary –
Been using this in several vehicles over long period,
Peter Savage –
Using the CRD fuel enhancer has provided almost immediate improvements in fuel economy.
Paul Hooker –
So far so good engine seems to be running cleaner
Mark –
It works to a certain degree witch is good. But the price is a bit expensive for what you get.
Vern Traill –
A good reliable product.
David Everingham –
Your product makes a big difference to the performance of the vehicle
Adrian E –
I’ve been using this for the last 60000 km in my CRD Jeep. It seems to improve all aspects of the motors running parameters but with only 90000 km on the clock it doesn’t seem to be showing any signs of wear and the motor in this car has been purported to show top end wear by this stage in its life. This purchase was my third small bottle which I religiously add to each tank refill.
Robert Carlson –
Great product, been using for two years on older Triton and has prolonged needing to replace the injectors.
Jonathan Rowbury –
It actually works
STEVEN –
Great product
Scott Radley –
Working well after only 2 tanks of fuel have noticed a difference
John Khoury –
Product is excellent. Works very well
Pat Aitchison –
Just started using this product, and feel I can already feel a difference. The motor appears to be quieter and smoother.
Matt McEniry –
I Put CRD Enhancer and fuel Decarboniser in two Diesels, over ten years old, and 170k kms, they both started running less noisily and smoother, and continuing to improve. Am I going to put it in the next tank? Of course! It gives me confidence that I can continue to keep the car for a while yet! First two tanks were double doses, now just using normal doses, had no problems.
Mark –
Used it on a couple of diesel vehicles as preventative maintenance.
Paul W –
Only just received the product and using in the first full tank of diesel.
Looking to purchase other items from the store in the future.
Bruce Hansford –
Great Product
Robert –

Kal Bruyn –
As per last review
customer –
Good product
Tyson McCully –
I didn’t think my Ford Ranger was noisy until I started using this. Wow, how wrong was i !! Im onto my 2nd tank of diesel using it and my mileage just keeps getting better and better. Yeah, I’d endorse this product for sure! I was skeptical, but i was wrong, this stuff really does work and it works well.
Rodney Hicks –
Excellent product will keep on using it
Charles Irvin –
It totally changed the injector sound and fuel economy of my old Hilux.
graham cole –
Only done one tank full at the moment , but i have noticed better start ups from my aging battery in the cold weather as my colorado is not used every day
Francis Maccan –
It seems to work well
I got an extra bottle for my mate to try.
Geoff Perry –
Great for common rail diesel.
Brett Polain –
Can’t really give a rating as I’ve only just put some in the tank.
Vince Fedele –
Has made a difference
Dian Pamilih –
Unexpectedly amazing result, recommend this to my friends straight away

Jason Johnson –
It works great product
Philip –
Not quite sure yet. Was highly recommend by a friend. I have only gone through a half tank so far. Will wait until I go through 2 tanks before I make up my mind. Nothing negative yet tho.
Royce Patton –

Gene Goodall –
Brilliant cheers
Jared Nichol –
Awesome product keeps injectors happy 😃
Mark –
Great value for money
Ric Holmes –
Great product. By the second tank I could hear, see (no smoke) and feel the difference. Can’t comment on economy boost as vehicle has gone from city to rural driving so already hitting in excess of 800km per tank. Ford Territory Diesel.
She now idles smoother, accelerates in a more linear fashion and has lost the startup rattle.
Product aside Jimmy is fantastic, couldn’t ask for a more friendly bloke to answer any questions etc. Keep up the great work guys 🙂
Peter Nickolas –
Used in the car running smoothly now
Ian –
I had been using another product occasionally. I had also tried 3 or 4 different brands. I can say that there was an almost instant improvement in fuel economy and injector rattle with the first tank full of fuel using this product. Quite impressed. Nealy 400,000 kms on a 2010 Dmax.
Robert Skeggs –
I’ve been using CRD fuel enhancer for around 4 yrs. now. Recommend it to anyone driving a diesel.
Grahame Fellows –
Been using it for 6 months now great stopped the injecter rattle I use it in every tank I highly recommend this product
Gary Bailey –
It definitely helps to keep my triton running clean
Rod –
Having tried many well branded additives in my time and lots money with little results, l can say this product lives up to its advertised claims at a cost that out ways its competitors per tank full.
Danny Vincent –
been using cleaner for 2 weeks ive noticed difference in fuel consumption things are only going to better in time i would recommend this product to friends
Rod Maxey –
CRD Fuel Enhancer was dispatched and arrived very quickly. .a matter of three days!
I use it when travelling and add it to diesel fuel that is not premium.
Robin Ball –
I have only used it in 3 tanks of diesel so far and I have noticed a difference in power and economy.
Anthony Jefferson –
I was told about this product and thought it would not do all that it is cracked up to be, but after running it through my old Toyota with nearly 300k on the clock what a difference it made. Improved power, better acceleration and no fuel burn.
I was told it was the best, now I am a true believer that it is.
Kevin –
Been using fuel enhancer for some years now in various SUVs I have owned and have past on to other people how good it works.
peter mccarthy –
Quality / noticeable straight away used in a Range Rover sport diesel , 190km fuel efficiency improved an engine sounds quieter
Thanks / recommended better value than cheap products at other retailers
Frank –
Purchased 250ml to try about 6 months ago after I discovered the injector values in my LC200 were high in at least 3 injectors (1.9-2.3) 345000ks at the time. Used 10ml per tank (when I remembered to) until I ran out on 2/2/23. Checked engine data on 3/2/23 and injector values for all cyclinders had returned to less than 1.0 (+ or -) 358000ks. This was the only thing I added to my normal maintenance schedule in that time. I can provide before and after photos of the data screen when connected to Toyota Techstream.
Rufus Hunt –
My injectors were noisy since new, they are definitely quieter since using CRD Fuel Enhancer. It’s economical to use it in every tank.
Ian –
Early days but appears to reduce engine noise
Need to evaluate over a longer period
Nick Duncan –
Great product.
Dan Bianchin –
Notice a difference just waiting to empty the tank to c
customer –
works a treat
Dale Casford –
After using this product I was amazed and so impressed at the difference it has made to my vehicle. I have used other products in the past and had very little improvement at all, but this was incredible with the gain of power and performance it has made and I could tell within a few short time, so thankyou.
trevor pye –
This product is very good for my diesel ⛽️ it improves performance and power
Paul –
I’m not a mechanic but after adding the fuel additive to my CRD Patrol, the engine definitely runs smoother and quieter.
It’s also improved fuel efficiency somewhat.
Happy with the results so far.
Tony Alevras –
Good product
Brendan –
Used in my 2016 gu patrol as a maintenance dose with no issues but when used in our low km np300 navara as a maintenance dose it caused injector rattle which it’s supposed to prevent. Cost me a great deal to try to diagnose the issue which none of the mechanics could. Only why I stopped using the product did the injector rattle stop. Maybe not suited to newer crd diesels.
Ron Smith –
Excellent product does what it says it does
Nathan –
Good product for lubricating fuel system. Slight change in injector noise. Smoother running.
Mr Stephen Thomas –
To early to tell
stephen welsh –
It’s to soon to say I’ve only done about ten kilometres
Jakob Carruthers –
My ute was running a little rough at idle. After putting 10ml in to the tank before re-fueling, it took 90 km before the idle was back to nice smooth operation.
D Sampson –
Fast turnaround and very helpfull
David Strubin –
It’s awesome
Mario Susic –
The fuel enhanser really works. you notice teh difference before you even go through 1 tank. Would highly recomend.
Garry McIver –
Appears to be assisting my engine
Tom Datson –
Pretty happy with the results so far. My prado only has 10,000km and swear the injectors are quieter. Hopefully keeps them going clean for many years to come
Adrian –
I wouldn’t use anything else as it do not compare. Well worth the money, does exactly what they say it does. Best products on the market!
Mark Halterman –
I was amazed at how much better my truck run it had a lot more power

marty vassallo –
Been buying this for 5 years, great product.
Thomas Rundle –
Great product and so much cheaper than rivals but works too
customer –
Made no difference to a Peugeot 2 litre diesel with a faulty number 3 injector……
Benjamin Aldridge –
Great product it keeps our Prado engine ticking over nicely
Marc Kerr –
Our 1GD prado only has 55000 km on the clock and has been run on premium diesel for all of its life serviced on schedual and has never had any problems. Heading out on a trip through birdsvile and the NT. Being unsure of fuel quality on our trip I thought an additive package to replace the additives in premium diesel couldn’t do any harm.
What surprised me is the rattle that these engines get at between 5 and 10k as they wear in is practically gone it’s as quiet as the day I bought it.
I can’t say if it has any other bennifits CEM list but the reduced engine noise on the almost 10000 km trip is worth the $50 alone.
Darren Hartley –
Have been using these products for about 6 years now.

Very prompt delivery with clear instructions. Haven’t had the need to refuel the Landcruiser so can’t comment on effectiveness yet. Looking forward to our next trip.
Aaron Reid –
We have used the CRD Fuel enhancer for a few years and it has saved us $000’s on my 2012 Hilux 3l diesel after our son accidently filled 2/3 of a tank with unleaded and then drove approx 80-90km(on our wedding day!!!) The vehicle wouldn’t start initially after that trip and once we recognized what had happened we drained the remaining fuel from the tank refilled with diesel, primed and it started straight up, I took it immediately to a engine rebuilding associate who performed a feedback test on the injectors and they gave a good as new result and the motor is still going strong 30,000kms later.
Lance Whitaker –
Been using card fuel enhancer for about 4years have no injector rattles or black smoke from the rear end, so that’s got to be good 👍
Stephen Williams –
It’s very early to say yet but so far I am very happy with this product.
Quinton Jacobs –
Very good additive that saves me $8000 for noisy injectors replacement, used with only 3 tanks filled and already less rattle noise. Feul pump also seems to be improved, have better start up.
George Kozlowski –
No complaints using this product
Don Smith –
I have been using CRD fuel enhancer for 11years and the injectors are quiet and fuel economy is great.

Luke Price –
Makes a huge difference
Michael Enright –
Great Product. Does what is says it will do and more. Very happy with purchase.
Gavin Nicholls –
Tried this product in several tanks of fuel and the vehicle now runs worse, so resorting to replace the injectors with a new set. I will give the product another go when injectors are replaced as part of a maintenance routine and see how it goes.
John M –
Too early to tell. Just arrived today. It took 18 days from QLD. Too slow.
Carolyn Gee –
Have been using CRD Fuel Enhancer as well as FTC Decarboniser in our 2006 Triton since 2013 to deal with possible dirty diesel in remote areas. Triton has been around Oz 3 times and is up to 315k and still going strong without any major repairs and just regular servicing. Gotta be happy with that.
Phillip Webb –
Engine is noticeably quieter and easier to start. Very happy with the product.
Vince Jubb –
Great product
Mark S –
I’ve been using CRD Fuel Enhancer in my 2014 Prado 3L D4D since new (now 160,000kms) and have had no injector or engine issues at all. This engine is apparently know for injector issues but I’ve had none so far. The Prado is used regularly for towing a 2.5t caravan and daily transport to mine sites.
Nick Duncan –
Took the injector rattle out of my ranger straight away .
Scott Azzopardi –
Great stuff, can really tell the difference when not using it
Gregory Drew –
Been using for 9 years. Great
DEAN DALY –

Cheers Dean
Marcus St Vincent –
I have been using CRD Fuel Enhancer now for over 5 x years in several diesel vehicles. The product is legitimately fantastic in diesel engines. Since using both CRD & FTC (Nissan, Mazda, SsangYong and Colorado) we have not had a single issue with any injector, HP fuel pump or DPF filter in that time. We now use in every new diesel we get from new and could not be happier with the results after more than 750,000 km collectively between all diesel vehicles. In fact all we do is regularly change oil & oil filter and the fuel filters and have not spent a single $ on any diesel engine component ever since using CEM products. We have also tested the effect on fuel economy and genuinely get close to an extra 100km per tank in all vehicles when using the diesel fuel additives. Smoke is ZERO, Engine noise is same as new as tested with a dB meter after several years and no clogged DPF ever which is almost unheard of these days.These products are seriously good and do make a big difference and I have absolutely no hesitation to recommend them to you if you’re not familar with them or haven’t used them before. I always sing their praises to everyone I meet that runs diesel vehicles and love the fact that CEM is Australian owned and produces such amazing products that do legitimately work and make a big difference in both diesel and petrol powered vehicles. YOU SHOULD TRY THEM- YOU WON’T BE DISAPPOINTED!!
Anthony Bate –
Have used this for 1 tank. Car seems to be running better. Feels smoother and idling better.
John Clive –
This stuff is so impressive I had to come here to review it. I’ve got a Mitsubishi Challenger 2.5 4d56 with 200,000ks, it’s started to get noisy injectors. Thought I would give crd treatment a try not expecting a great deal. Well the injector rattle is markedly improved and I reckon I’ve delayed an expensive repair. I noticed a nice increase in power and responsiveness which was not expected, power increase was noticed within less than 100km’s. I’m onto the 3rd tank now, first 2 tanks were double dosed and it’s still improving!? I have no idea what this is made of but it is an absolute must for any diesel new or old. If I had only started using this 100,000k’s ago…. Very cost effective and a must must must have for your diesel.
Kathleen –
Found this product incredible saved us $35000 for new injectors
Mark Hansen –
have been using the CRD fuel enhancer now for the last half dozen tanks and the vehicle appears to be running well and cleanly better than before and if it keeps the fuel pump and injectors in good condition that’s all I want.
John Briggs –
Bought this to try to quiet some noisy injectors. The car was running fine, just a noisy Mitsubishi 2.5 with 200,000k’s. Within 20k’s (twenty) of adding there was a definite improvement in responsiveness which was completely unexpected and a definitely noticeable increase in power in the mid range, very nice. I’ve only done about 300k’s in total so far with a double dose of crd and the injector rattle has already improved. It has gone from a “pinging” type sound to now just sounding like a rattly diesel, as it should. If this is all I get I’m more than happy but I’m sure after another couple of tanks it should only improve more once the system is nicely cleaned. For the cost per tank and absolute simplicity of use, (not a spanner or workshop in site) this is an absolute must for any turbo diesel car, especially with the hit and miss diesel fuel quality we have. I would much rather buy this product that absolutely works from a local company than something imported. So highly recommended, I don’t know what it is and how such a small amount does so much but this product is the only tank additive I have ever used in decades that has had such an immediate positive effect.
Robert Martin –
I like the products, and use them regularly
Luke Howell –
Great product CRD additive is working a treat better sound from the engine and fuel economy
Trevor Blanch –
picked up a Prado with the 1kd motor with 350k on it had a slight rattle/tick. since running the common rail additive I’ve found the injectors to all become quieter and the engine running smoother. I highly recommend these guys!!
Stuart Gillies –
Great service. Fast delivery with good products
Mark Benz –
Great product CRD, has improved fuel economy by about 50km per tank.
Rob Shaw –
The best thing I could of ever do for V8 land cruiser as I had bad fuel so water in fuel and coursed injection nock by googling this products I tried it and problem fixed. I was looking at having to replace my injectors at $5000.00 . So very impressed so thumbs up 👍.
Craig Cox –

Gary Symonds –
My D-Max is 7 years old and has 200K on the clock. The CRD additive in the fuel has improved economy, helped it work easier and cleaned up the insides of the engine. A great product.
