MPT ZDDP Zinc Additive reduces wear in camshafts and lifters in high-performance engines. The use of ZDDP (Zinc Dialkyl Dithiophosphate), however, shortens the life of a street vehicle’s emissions system. The Environmental Protection Agency (EPA) has mandated that the zinc level in motor oil be reduced to near zero, due to the harmful effects on catalytic converters and emissions systems. American Petroleum Institute (API) approved motor oils now currently contain less than one tenth of a percent of ZDDP – a mere fraction of what was previously allowed.
- Increases zinc levels for better engine protection
- Designed for racing engines and high performance off road or industrial applications — not for passenger vehicles
- Protects older engines that require higher levels of zinc
