This premium oil additive helps protect the internal components of your engine by putting back the ZDDP that has been removed from all domestic oil by the EPA. ZDDP or Zinc Dialkyl Dithio Phosphate alters bearing and journal surface characteristics to prevent metal-to-metal contact and galling that can cause serious damage in your engine. Each bottle contains 4-oz. and should be added at every 4-6 quart oil change.
