If you project vehicle is pre-1989, ZDDP Plus 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 prevent premature deterioration. However, the U.S. government ruled that ZDDP could no longer be put into domestic motor oils starting in 1989, so today's motor oils won't provide the ZDDP your older engine needs...unless you add this ZDDP Plus Oil Additive!

ZDDP alters bearing and journal surface characteristics to prevent metal-on-metal contact
ZDDP reduces the tendency of parts to scuff or gall under heavy loads
Add a 4-oz. bottle of ZDDP Plus to every 4- or 5-quart oil change

About ZDDP Plus Oil Additive 3 Pack

After 70+ years, the EPA mandated that all domestic motor 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 still require ZDDP to avoid premature deterioration. Our ZDDP Plus Oil Additive puts back what your pre-1989 engine needs!
