REV-X ZINC Oil Additive is necessary for new engines with flat tappet cams/lifters to ensure proper break-in and long life. When ZINC (ZDDP) is heated, an anti-wear layer is created on cams, lifters, and crankshafts, preventing them from contacting other components and shortening their service life.
ZINC may also be used in any vehicle (1980s and older) when engine oils use ZDDP, minimizing lubrication-related failures. When blended with six quarts of oil, two fl. oz. of ZINC will achieve a maximum level of 3200 ppm (Ideal for new engine break-in); for properly running engines seeking additional protection, use one fl. oz. of ZINC (to achieve a 1500-1800 ppm level).
As REV X ZINC Oil Additive (ZDDP) is heated, it creates a film that coats the engine parts with an anti-wear layer. Think of it as a sacrificial layer that will wear away, preventing the wear on your vital engine parts. As the name suggests, ZINC benefits flat tappet motors with a flat lifter.
When the engine runs, the cam lobe is in constant contact with the tappet’s flat surface. Simultaneously, this creates high temperatures due to the friction between the two. If the protective film produced by the ZDDP were not present, this heat and friction would wear away at the lifters and cam, leading to engine failure.
