ZDDP Plus Oil Additive 3 Pack

    Item #EW503323Z


    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
    • Economical 3-pack

    About ZDDP Plus Oil Additive 3 Pack

    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 tendancy 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.

    Review by dave
    Read about, then tried ZDDP oil additive. My 350 oil pressure would drop to 20# at idle and 60 at higher rpm's. After adding ZDDP it now idles at around 40-45#. Thanks Eastwood.! The product did what they said it would do. :)
