Offers Protection to Flat Tappet Cams

High-performance vehicles and classic cars contain flat-tappet camshafts with cam lobes and lifters. They quickly slide over one another, causing high-heat and high-friction. This friction can lead to wear on the cam and negatively affect the operation of valves. This reduces engine efficiency and power. These parts of the motor also aren’t pressure-lubricated, but are instead splash-lubricated, adding strain on phosphorus and zinc anti-wear ingredients.

AMSOIL Z-ROD® 20W-50 Synthetic Motor Oil is engineered with elevated amounts of ZDDP (zinc  dialkyldithiophosphate) which protects rockers, flat-tappet cams, lifters, and other important motor components in classic cars from wear.
