Lubrication Kit, ZDDPlus Oil Additive & ZDD Paste ZDDPlus - The original Zinc oil additive packaged along with ZPaste for initial engine break-in.

For more than 70 years ZDDP (Zinc Dialkyl Dithio Phosphate, containing Zinc and Phosphorus) was a mainstay of motor oil, providing trouble-free engine protection. The E.P.A. has now forced most ZDDP from domestic motor oil, including diesel oils. This lack of zinc and phosphorus is most severe in the just-released 'SN' (ILSAC GF-5) rated oils.
