Where Oil Goes and What it Does

A typical engine has hundreds of parts which must be lubricated, sealed, protect, and cooled by motor oil. Motor oil must do this under tremendous heat and stress. Valves, seals, piston wrist pins, main bearings and camshafts are just a few of the internal parts of an engine that require constant lubrication.
AMSOIL SIGNATURE MOTOR OIL provides 90% more protection against sludge build up and 50% more detergents to help keep engines clean. Read More about how oil is a dynamic enabler of performance here.
