RAY: First of all, while denatured alcohol is a solvent, we have no idea whether it does anything to remove engine sludge
In addition, the coatings also reduce engine sludge
build-up, allowing the engine to maintain balance for more horsepower.
Diesels suffer from the problem of soot build-up to a greater extent than petrol engines and so the oil you put in the sump needs to have greater soot handling abilities to prevent the build-up of engine sludge
Early results from the partnership included identifying the causes and chemistry of engine sludge
and deposit formation, developing a fundamental understanding of low-temperature wax formation in diesel fuels, analyzing engine exhaust emissions, understanding diesel ignition and combustion, and evaluating fuel alternatives for spark ignition and diesel engines.
MB OM611 and OM441LA address a number of performance criteria, including boost pressure lost, bore polishing, cam wear, cylinder wear, engine sludge
, general engine deposits, oil consumption, piston ring wear, deposits and cleanliness, ring sticking, timing chain wear and viscosity increase at 100 Celsius.
Owners of both higher-mileage and newer vehicles can drive with renewed confidence thanks to a new line of ExxonMobil synthetic-blend motor oils, formulated to help clean and restore performance of high-mileage engines and help prevent engine sludge
build-up in new vehicles.
