2 Bottles of ZDDPlus Engine Oil Additive

$23.75 $24.99

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 (extremepressure) ingredient in all quality motor oils for over 70 years. In the late 1980s, however, the concentration of ZDDP in motor oils has been greatly reduced as newer oil classifications have come on the market.

ZDDP is an essential cam wear solution for classic and performance cars. ZDDPlus™ is the original, best researched and documented zinc additive available.

The sliding cam-to- cam-follower interface in a non-roller lifter engine requires a special anti-wear additive, which has historically been ZDDP. After 70+ years of positive protection afforded by ZDDP, emission system changes are forcing a reduction in the amount of ZDDP in motor oils, leaving your classic or performance car at risk of premature cam and lifter wear. The key ingredient of ZDDPlus™ is ZDDP. ZDDP has been known to shorten catalytic converter life. Manufacturers have been redesigning engines for several years to extend the life of catalytic converters in order to lower emission levels. One engine redesign has been the switch to roller rockers. As a result, oil manufacturers have agreed to reduce or eliminate ZDDP from motor oils.
