AMSOIL Fast Acting Engine Flush is made from a carefully selected blend of solvents and special cleaning agents that dissolve and disperse harmful deposits formed in the crankcase, cylinder walls, pistons and rings of an internal combustion engine.  When used as directed, it cleans and restores operating efficiency to valves, valve lifters, rocker arms, and pistons for improved horsepower, fuel economy, and performance.
One treatment of AMSOIL Engine Flush cleans engines for reduced wear and longer engine life. Use before changing oil.

Why Clean Your Engine?

Chances are, when your engine was new it delivered the power and fuel efficiency it was designed for.  But now, as your engine accumulates miles, things are happening that are adversely affecting its performance.  Slowly but surely, your engine is gathering harmful deposits that will eventually cost you money.

Even though you may follow a routine service schedule, your driving conditions may be far from routine.  Stop and go driving, prolonged periods of idling, short trips that don't allow your engine time to warm up, towing a trailer, the ingestion of airborne dirt, fuel dilution, water condensation, and oxidized oil will eventually cause the formation of a thick, gummy deposit known as sludge.  Settling throughout the engine, sludge will clog oil passages, restricting the flow of oil to vital engine parts, especially in the upper valve train areas.
