From Eastwood.com
"After 70+ years, the EPA mandated that all domestic oil producers remove ZDDP (Zinc Dialkyl Dithio Phosphate) from all conventional and synthetic motor oil. If your engine was designed before 1989 the non-roller lifters require ZDDP to avoid premature deterioration. ZDDP also alters bearing and journal surface characteristics to prevent metal to metal contact. Under extreme conditions like a high performance motor, ZDDP reduces the tendency of parts to scuff or gall under heavy loads. Simply add ZDDP-Plus to every 4-5 quart oil change and your motor will be protected from metal to metal contact. Add one 4 ounce bottle to a 4-5 quart oil change
modifier to eliminate and metal-to-metal contact ."
