ZDDP Oil Additive

4 oz.

Eastwood 12269Z Features:

If you project vehicle is pre-1989, ZDDP Oil Additive is a must for keeping that engine running smoothly. ZDDP alters bearing and journal surface characteristics to prevent metal-on-metal contactZDDP reduces the tendency of parts to scuff or gall under heavy loadsAdd a 4-oz. bottle of ZDDP to every 4-6 quart oil change If your engine was designed before 1989, the camshaft's non-roller lifters require ZDDP in the motor oil to prevent premature deterioration. 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!

Includes:
4 Fluid Ounces

Protect Your Classic Engine with Eastwood ZDDP Oil Additive

Keep your vintage engine performing like new with Eastwood ZDDP Oil Additive — a must-have for pre-1989 vehicles. Specially formulated to prevent metal-on-metal contact, ZDDP (Zinc Dialkyl Dithiophosphate) enhances bearing and journal surfaces while minimizing scuffing and galling under high loads. Since modern motor oils lack ZDDP due to 1989 EPA changes, your non-roller camshaft engine needs this additive to avoid premature wear. Just one 4-oz. bottle per 4–6 quarts of oil delivers the protection your classic car demands.
