1. ZDDPPlus ZDDP Engine Oil Additive Zinc & Phosphorus 10 Bottle Pkg

Feature

Prevents premature cam and valve train failure
Extreme pressure protection
For use on pre-1989 engines
Use in high-performance and classic cars

Description

ZDDPlus is an oil supplement that contains very high concentrations of the well-known additive ZDDP (Zinc Dialkyl Dithiophosphate), which has been the primary EP (extreme pressure) ingredient in all quality motor oils for over 70 years. However, beginning in the late 1980s, the concentration has been greatly reduced as newer oil classifications have come on the market. ZDDPlus is the ONLY EP (Extreme Pressure) component which re-establishes the ZDDP levels that classic car engines were designed for, while allowing the car owner to use the base oil of their choice. ZDDPlus also alters bearing and journal surface characteristics to prevent metal to metal contact. Under extreme conditions like a high performance motor, ZDDP reduces the tendency of parts to scuff or gall under heavy loads. While some off-the-shelf additives may have some ZDDP but the amount per bottle is small. ZDDPlus is not a typical oil additive. It is compatible with all conventional and synthetic oils intended for automotive use. By adding a small 4 ounce bottle of it at every oil change, an adequate amount of Zinc and Phosphorus will continue to protect your engine.

9. MPT MPT-323 ZDDP Zinc Additive - 4 fl. oz.

Feature

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

Description

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.
