Oil Additive, ZDDPlus 4oz


Bottle, 4 Ounce, Ounces

SKU: ZDDP4OZ Category: Tags: ,


ZDDPlus™ contains the proper concentration (approximately 0.15%) of ZDDP (Zinc DialkylDithioPhosphate) that was available in motor oils under the “SF” category (today’s motor oils are “SM” rated).

Today car manufacturers must warranty their catalytic converters for 100,000 miles or more. In order to meet this requirement, oil companies have had to eliminate the ZDDP needed to protect flat-tappet cams, found in many PD engines (such as BRM, BEW, and BHW).

ZPPD protects by creating a film on the cams and flat lifter contact points.
