ZDDPlus - ZDDP Oil Additive

    Item #50332 ZDDP Oil Additive

    Details

    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 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. Add one 4 ounce bottle to a 4-5 quart oil change modifier to eliminate and metal-to-metal contact .

    "ZDDPlus" is the best insurance to protect your classic or high-performance flat-tappet engine!" says NHRA's #1 Drag Racer of all time, "Big Daddy" Don Garlits.

    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.

    I started using it in my motorcycles and have immediately noticed smoother shifting and idle. Smoother running at all rpms.

    The EPA is out to KILL older engines all for their almighty catalytic convetors.

    Screw the Feds, Im protecting my rolling stock!

    Just finished a big block Mopar for a guy. Has a "flat tappet" cam. busted that baby off with good old Penn 30w in it along with the ZDDP. Ran the cam in without any issues at all. Good oil pressure, right on temp, and no noises other than the VVVRRROOOOOOOMMM you expect from a well built Big Block Mopar.

    Use it. It works

    With the higher working tappet pressures of high compression '60s - '70s engines and cam profiles on non-roller cams and the Feds removing or radically reducing this from all modern oil due to CAT and EPA/CAFE concerns I have wipped out more then one cam due to this problem. Even Rotilla has dropped levels of Zinc Disolphate to marginal levels at best. Add a bottle of this to your oil change and rest assured it will have enough ZDP to eliminate cam and lifter scuffing. Great product, thanks for offering it!
