Today's readily available motor oil is formulated specifically for new cars and their rocker arms. An additive, ZDDP, has been reduced over the years to a level now where using modern oil in a flat tappet equipped engine can cause excessive wear on your camshaft. ZDDPlus Restores ZDDP (ZINC) to the optimum level, which existed when your classic car was designed. Adding a 4 oz. bottle each time you change your oil will significantly reduce camshaft wear. It's compatible with all the new formula, high quality oil, so add ZDDPlus to your oil routine and give your engine the protection it deserves. Use one 4 oz. bottle per oil change.
