Independent Testing

While field tests and customer reports provide valuable information for potential users, controlled testing conducted by independent, recognized authorities ensures that testing procedures are repeatable, reliable and have a high degree of accuracy. The procedures used should also adjust for variation in ambient conditions.

DT80 Testing on Premium Diesel Treatment

ABSTRACT

This paper investigates the claim made by numerous users of Cost Effective Maintenance (CEM) products, that their “vehicles and equipment run better than they did when new”, when using CEM products. To determine if these claims are valid, and if so quantify any benefit, Cost Effective Maintenance contracted an independent, Australian government approved testing facility to conduct testing on a brand new Isuzu DMax 4×4.

BACKGROUND

The Brisbane City Council is approved by the federal government to conduct the recognized test procedure for diesel vehicles, known as the DT80 Test. The primary purpose of the test is to measure diesel exhaust emissions, and in doing so, it also accurately determines fuel consumption in grams of CO2/km (which can also be directly converted to L/100km). The DT80 Test involves operating the vehicle through a cycle that simulates real life driving conditions, on a dynamometer. The authorized technician accelerates the vehicle from running in gear at idle speed, to 80kph (with foot to the floor). On reaching 80kph, the vehicle is braked, and idled again for 10 seconds, before repeating the procedure. On the third acceleration, 80kph is maintained for 60 seconds, before completing the test. Throughout the whole procedure, the dynamometer is set to simulate a load of half the maximum vehicle payload. While the vehicle is undergoing the DT80 Test, exhaust gases (NOx, CO2 and Particulate Matter) are continually sampled and analysed. The data is logged at one second intervals, including instantaneous vehicle speed. Quality Assurance testing is completed prior to each individual DT80 run. Results are corrected for variations in ambient conditions. As part of compliance with federal government approvals, the dynamometer and associated data recording equipment must be maintained in strict accordance with mandatory protocols.

OPPORTUNITIES for EFFICIENCIES in BRAND NEW VEHICLES & EQUIPMENT

(Modifications and aftermarket devices are not considered here, as these can affect warranty.) Promoting a faster and more complete fuel burn, will result in release of a greater portion of the fuel’s energy being released closer to piston top dead centre, where it is more effective in producing power. In doing so, it is important not to alter the fuel specification. A diesel engine operating at around 2000rpm typically loses 25% of its power to frictional losses within the engine. Approximately half this is attributed to the piston ring and cylinder wall contact. Frictional losses in the drive train account for a further 10-15% power loss. Clearly, there is scope to improve overall efficiency where these losses can be reduced. With diesel engine fuel systems running increasingly higher fuel pressures, and multi-step fuel injections per firing cycle, precise injector response is paramount. These high pressures also produce a high fuel temperature, and combined these conditions can cause the diesel fuel to degrade within the fuel system. The result is deposit formations and loss of fuel lubricity, which can inhibit injector response.

CLAIMED BENEFITS of the TEST PRODUCTS

The package tested is produced by Cost Effective Maintenance, and known as the Diesel Performance Pack, which contains:

  •  A lubricant assistant, known as AW10 Antiwear, which has been demonstrated by the Falex Test to reduce friction and wear in laboratory type conditions.
  •  A fuel system cleaner, which also increases diesel fuel lubricity, known as CRD Fuel Enhancer, has the potential to reduce fuel temperatures within high pressure diesel injection systems, and improve injector response.
  •  An engine decarbonizer and combustion catalyst, known as FTC Decarbonizer, with an established record of improving fuel efficiency in laboratory and field trials, most notably with open cut mine mobile equipment.

TESTING THE CLAIMS

Cost Effective Maintenance purchased a new (2017) Isuzu DMax ute fitted with a 3.0L common rail turbocharged, intercooler diesel engine. It also features the diesel particulate filter (DPF). Vehicle “running in” time was allowed prior to actual testing, and the vehicle was running with all three treatments during the run in period. This ensured that there was minimal chance of any build-up of deposits that may favour the products under test.

diesel vehicle tested for emissions

Thus the initial series of DT80 tests was performed on 26.10.2017, with the vehicle treated with AW10 Antiwear in the engine, both diffs, gearbox and transfer case. The Shell brand diesel fuel was treated with a mix of the FTC Decarbonizer and CRD Fuel Enhancer. The DT80 Test was performed four times.

After the test was completed, all oils were drained and replaced with the Isuzu recommended oils, without any treatments. The DMax was subsequently fuelled with untreated fuel only, and once again presented for the untreated DT80 Test on Shell fuel. Another four runs of the DT80 Test were performed two weeks (2385km) later on 9.11.2017.

The results are summarized below in Figures 1 and 2:

(Note: All exhaust emission figures were very low, well below threshold limits, but are not relevant to the scope of this work.)

CONCLUSIONS

The independently conducted DT80 Test does support customer comments that their vehicles and equipment “run better than they did when new”, by confirming significant improvements in both fuel economy and acceleration.

RECOMMENDATIONS

One feature of computer controlled diesel engines, is that maximum power is usually restricted, and we saw evidence of this in some components of the DT80 Test procedure. Further work is recommended across a wider range of power settings.

This product is the real deal I have a 2005 pajero diesel with 500,000kms on the clock the auto was... starting to play up and it has always ran hot when towing since adding the aw10 to all systems the car is running very smoothly and the automatic is totally different….I really can’t explain how much difference this product has made but before adding it I was getting quotes on rebuilding or replacing the automatic!Not now 😀Thanks guys keep up the good workread more

I normally think of most additives as snake oil, I have to say though, two seperate vehicles... responding to just the FTC decarboniser and the CRD Fuel enhancer, both showing far more available torque and hell of a lot quieter operation. That, and it’s an Aussie run company, definitely recommend at least trying their stuff in your own rig, it’s made a difference in mine and a mates that’s for sure.read more

Carried out the engine oil flush on port side volvo penta 6cylinder was show excess pressure coming... from breather and used fuel additives also.Definite reduction in smoke out the exhaust was happy with result there.Still too much blowby so removed head I diagnosed poss head gasket which turned out to be correct with head bolts not very tight from previous work carried out prior to my ownership.I was happy with the fact that all cylinder showed hone marks and no glazing which I believe the flush coorrected hence the reduction of smoke.Recommended fuel additive to a workmate who was blown away by immediate results and has saved him buying new common rail injectors in his Hiace. Highly recommend your Productsread more

I have a 2011 Western Star Detroit DD15 with 1.3 million kms, used for all sorts of work including... up to triple road trains. I have been using FTC Decarboniser and ran an oil flush through it at 1.1 million kms. Still does not use a drop of oil between 20,000km service intervals. Had my mechanic pull the sump off to do a bearing roll at Christmas and we found insides spotless, even still has cross hatching in the bores!

Bought Decarbonizer and the Flushing Oil Concentrate to use on my tractor and excavator, sadly a... bit too late for the digger....needs a rebuild. But the tractor was a definite improvement, the engine ran sweeter and a lot less gunk from the exhaust, really noticeable. Thoroughly recommend, the only suggestion is to maybe reconsider the product names....bit confusing. But names are not everything, absolutely worth the money. Many thanksread more

Frankly, I am astounded with the difference. I have been using the FTC Decarbonizer for the last... 1,500k. My mechanic has warned me the engine on my Winnebago Motorhome (Chevy 6.5L turbo diesel, 17 yrs old, 225k on the clock) was exhibiting signs of blow-by. There is now no evidence of smoke from the exhaust under load, the performance has improved, the engine just runs smoother, but incredibly it starts first time after being a difficult starter for several years. I am looking forward to its next service to see what the mechanic has to say. Great product.read more

I have used the AW10 in several cars now. It has made a HUGE difference in all of them. My little... junk Barina that I drive to the train station had a noisy engine and it got hot fast. After using the AW10, it is quiet and the temp takes a while to get to it's working temp. The car runs really well now. All the other cars are running well too.The Rust Conqueror is AMAZING. Works so much better than anything else I have tried. I first saw the XTroll rust treatment way back in the late 80's. It was fantastic back then. Over time I lost the can and moved states. I needed to treat some rust and nothing I used worked properly. I searched for the XTroll and found it with the Cost Effective Maintenance team. They were so helpful. The stuff isn't cheap but it is more than worth it. You want your equipment to last, Use the AW10 and XTroll. Look at the other products too. You won't regret it.read more
