Eastwood ZDDP Oil Additive for Pre 1989 Car Engines | 4 oz Bottle | 2 Pack

If you project vehicle is pre-1989, ZDDP Oil Additive is a must for keeping that engine running smoothly If your engine was designed before 1989, the camshaft's non-roller lifters require ZDDP in the motor oil to reduce premature wear. However, the U.S. government recommended that ZDDP no longer be put into domestic motor oils starting in 1989, so today's motor oils won't provide the ZDDP additive your older engine needs...unless you add this ZDDP Oil Additive! ZDDP alters bearing and journal surface characteristics to reduce metal-on-metal contact ZDDP reduces the tendency of parts to scuff or gall under heavy loads Add a 4-oz. bottle of ZDDP to every 4-6 quart oil change.
