engineOptima Fuel System Cleaner when added to gasoline rapidly cleans clogged injectors and restores proper spray patterns. It will remove water from the fuel system and helps prevent rust and corrosion.

Most gasoline products contain ethanol. Ethanol can enter the crankcase as a blow-by gas. When this happens, the ethanol can mix with water from condensation and form a white sludge. TerraClean Engine treatment prevents the formation of this sludge and protects the engine from friction and wear.
