Hy Carbon Diesel Engine Cleaning is a way of cleaning away the build-up of carbon deposits from the inside workings of an engine.
Auto Experts have invested in the equipment to carry out this service.
Does this same principle work on Petrols?
The answer is YES! Go to our other post that shows the results of a Volkswagen Polo petrol engine clean.
We tested and made comparisons of quite a few diesels and in 90% of cleans, improvements where noticed.
The owner of this 2010 Mazda 6 diesel 2.2 litre drives 60 miles a day to and from work. You would not think that this car would suffer with a carbon build up so this would be a good way of highlighting the improvement after carrying out a Hy Carbon Diesel Engine Cleaning process.
We warmed up the car and carried out a smoke test when the oil temperature got to 80 degrees Celsius. Look at the picture and you will notice that the ‘Absorption Coefficient’ reading before the Hy-Carbon cleaning process was 0.69 1/m
To understand what ‘Absorption Coefficient’ means, in layman’s terms it is how quickly the light passes through what is emitted from the vehicle’s exhaust (i.e. Smoke through a unit of a 1 metre thickness of air). The smaller the number, the more transparent the smoke is and the better and cleaner the engine is.
We carried out the 1.5-hour Carbon Cleaning process and the car was then taken for a short drive to clear any remaining hydrogen from the engine. After this drive, we allowed for the engine to cool so that we could get a like for like comparison.
The car was retested at 80 degrees Celsius and the Absorption Coefficient amount of emitted smoke had reduced to 0.28 1/m
Moreover the owner has noticed that the car’s engine appears quieter and feels much more responsive, especially on first start up.
Auto Experts charge £80 for the 1.5 hours clean. See our Carbon Cleaning Offer on our Vehicle Servicing Tab.
