Mr. Gasket Zinc Engine Oil Additive

Protect your camshaft and flat tappet lifters with a bottle of Mr. Gasket Zinc Engine Oil Additive. Modern motor oils no longer include the zinc, ZDDP, and extreme pressure additives needed to properly lubricate the cam and lifters. One 4 oz. bottle effectively treats 5-7 quarts of oil to prevent scuffing and galling, with protection for the valvetrain on your muscle car, hot rod, street rod, or classic car. This fluid is compatible with synthetic, petroleum, and blended motor oils. Add a bottle to the crankcase of your engine at each oil change. (Use with Pre-ODB and off-road vehicles.)
