At CEM, one of the most common problems we get asked about is stuck rings, and how to fix low compression on an engine. So when we saw this old 1997 Toyota Corolla on its way to the wreckers, we though this could be an easy save!

This Toyota Corolla has 207,000 kms on the clock, and had received absolutely NO servicing for the last 4 years. The first step was to establish a baseline by way of a compression test, and yes, as the video shows, it revealed low compression, and two weak cylinders. It was dead easy to use the Flushing Oil Concentrate to restore full compression to the weak cylinders, and 40 minutes later, we’d taken the measurement to confirm it.

Some engine flushes are simply not capable of dissolving hard, baked-on carbon, but Flushing Oil Concentrate (made by Cost Effective Maintenance) is designed to do just this. Safely. Simply. And quickly.

Using Flushing Oil Concentrate, it takes just 3 easy steps to fix low compression on a Toyota engine:

1.  Add Flushing Oil Concentrate at 12.5mL per litre of oil capacity to clean oil
2.  Park the vehicle up, and run at a high idle for 30-45 mins
3.  Drop the oil, and replace with new oil

Job done! The rings are now clean, compression is up, and power is up! In addition:

• The idle speed has increased by 300rpm, so had to be re-set
• The engine is much quieter, and smoother
• It revs out more freely
• The small amount of exhaust smoke has disappeared
• It starts faster
• The hesitation when taken off idle, has disappeared

So whether you’ve got a petrol or diesel engine, if it’s got a bit of age on it, it’s likely that it’ll be down on compression and power. The reason for this is simple…carbon build up around the piston rings! If you clean up the carbon, the rings seal better…and that means more compression and more power!

In this particular case, you could have spent a lot of money unnecessarily on an engine rebuild, to achieve the same result. However, as you can see, we’ve quickly and easily achieved a significant level of rejuvenation to the engine with very little effort, or cash. We’re now confident, that whoever decides to buy it will have a good little car with plenty of life left in it.
