    1 Review(s)


    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 10-pack

    About ZDDP Plus Oil Additive 10-Pack

    After 70+ years, the EPA mandated that all oil domestic producers remove ZDDP (Zinc Dialkyl Dithio Phosphate) from all conventional and synthetic motor oil. If your engine was designed before 1989 the non-roller lifetrs 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 tendency 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 Vintage car guy
    I am planning on getting my oil analyzed shortly to see how much is actually in the oil when compared to original levels from a few years ago. It turns out many of the European performance cars strictly recommend using oils provided by their companies and discourage using any normal oil brands because this vital ingredient has been significantly reduced. Still maintained in high levels in off road racing versions, so all in all this product should be used in older cars as well perhaps new ones that are high performance models. So far this product performs well.
