Motul Engine Clean is an advanced engine flush additive formulated to clean and protect 4-stroke engines deeply before an oil change.
Designed for both individual enthusiasts and professional service centers, this internal cleaner effectively dissolves and suspends harmful sludge, varnish, carbon buildup, and other residues that accumulate over time inside the engine.
By cleaning vital components such as hydraulic lifters, piston rings, oil galleys, and valve trains, Motul Engine Clean helps restore lost compression, optimize oil flow throughout the entire system, and improve overall engine response.
This product is compatible with a wide range of vehicles, including trucks, motorcycles, passenger cars, scooters, ATVs, UTVs, personal watercraft, and other powersports machines that use 4-stroke gasoline or diesel engines.
Whether your engine is turbocharged, naturally aspirated, or equipped with emissions systems like diesel particulate filters or catalytic converters, Motul Engine Clean is safe to use and delivers noticeable performance improvements with no negative impact on sensitive components.
Motul Engine Clean is added directly to the old engine oil just before an oil change.
Once poured in, the engine should be run at idle for about 15 minutes to allow the formula to break down contaminants and suspend them in the oil.
After draining the oil, simply replace with fresh oil and a new filter.
The result is a cleaner internal environment that maximizes the protection and longevity of the new oil and helps maintain optimal engine health.
Ideal for high-mileage vehicles, regular maintenance, or engines showing signs of sludge buildup, Motul Engine Clean is a proven way to reduce emissions, restore peak performance, improve fuel economy, and extend engine life.
It’s a trusted solution used by automotive and powersports professionals around the world to keep engines running smoother, cleaner, and longer.
