Engine oil pretreatment is a modern, high-performance additive for stabilizing the viscosity of engine oils. It reduces oil consumption across piston rings and valve guides in gasoline and diesel engines. Prevents blue smoke and oil mist and protects the falling viscosity of engine oil. Increases pressure and reduces engine noise on hydraulic tappets. It provides additional protection for high-wear engines, and extends the life of environmental filters. An engine oil additive for engines showing symptoms of wear.
