Product Overview
ZDDPlus Additive.
After 70+ years of trouble-free, metal to metal engine protection, the E.P.A. is forcing ZDDP (Zic Dialkyl Dithio Phosphate=Zinc and Phosphorus) from domestic motor oil.
If you engine was designed prior to the 1990s, the non-roller lifters require ZDDP in the motor oil to avoid premature deterioration. DonAEt let the lifters run metal to metal. Keep ZDDP, via ZDDPlus, in your motor oil.
Add the 4 fluid ounce contents of a bottle of ZDDPlus at every 4 to 5 quart oil change. It's the perfect solution for owners of classic and high performance vehicles.
Order the 6 pak of ZDDPlus quantity and save 10%.
