Eastwood ZDDP Oil Additive
Eastwood ZDDP Oil Additive has been designed to remove ZDDP(Zinc Dialkyl Dithio Phosphate) from all conventional and synthetic motor oils. If your engine was manufactured before 1989 the non-roller lifters require ZDDP to avoid premature deterioration. Eastwood ZDDP Oil Additive 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. Eastwood ZDDP Oil Additive should be added to every 4-6 quart oil change. Which in return will give the added protection your motor needs.
