1 quart (946cc) bottle. JASO-MA. Formulated to resist oxidation, reduce temperature and 'thinning out' at high crankcase temperatures. Super slick to reduce friction and increase efficiency at maximum RPM. Designed to resist breakdown from contamination by racing fuels. Does not contain aggressive additives that could be harmful to the engine. For any application that requires a heavier motor oil, add Lucas Heavy Duty Oil Stabilizer (910407 mineral or 910408 synthetic) to obtain the desired viscosity.
