As an official distributor of ZDDPlus™, we are committed to providing our customers with oil additives that have been tested and proven to provide important lubrication benefits to their vehicles. ZDDPlus™ is essential for your older vehicle with a flat tappet lifter cam engine. ZDDP has been proven to alter bearing and journal surfaces characteristics to prevent metal to metal contact.
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. 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.
“ZDDPlus is the best insurance to protect your classic or high-performance flat-tappet engine!”— “Big Daddy” Don Garlits, NHRA’s #1 Drag Racer of All Time
