ZDDPlus - Zinc oil additive dedicated to Protecting Your Classic, High Performance, Racing, and Industrial Engines!
For more than 70 years ZDDP (Zinc Dialkyl Dithio Phosphate, containing Zinc and Phosphorus) has been a mainstay of motor oil, providing trouble-free engine protection. The E.P.A. has now forced most ZDDP from domestic motor oil. This lack of zinc and phosphorus is most severe in API-classification 'SM' oils. In a few months we'll begin seeing 'SN' (ILSAC GF-5) rated oils, with even lower levels of zinc and phosphorus.

If your engine was designed prior to the 1990s, or if you're running a modern high performance motor with a flat tappet camshaft, your non-roller lifters require ZDDP zinc oil additive to prevent metal-to-metal contact and subsequent deterioration. Newer testing, even mentioned in one oil manufacturer's advertising, attributes piston scuffing to the decreased levels of zinc and phosphorus.

Don't let metal-to-metal contact destroy your new engine...
...4oz's (1 bottle) of  ZDDPlus added at every 4 to 5 quart oil change provides the correct amounts of zinc and phosphorus in your oil, protecting your investment.

ZDDPlus contains the proper amount of ZDDP to give at least 0.18% zinc and 0.13% phosphorus level when a single 4 ounce bottle is added to a 5-quart oil change. This level of zinc and phosphorus is the level designed into pre-OBDII oils. Using ZDDPlus affords you total control over the choice of oil brand and viscosity, ensuring the protection of your solid lifter motor. ZDDPlus is compatible with any oil, including synthetics, and is compatible with the additive packages present in any modern-day oil. ZDDPlus does nothing more than put the exact same molecules, zinc and phosphorus, back into your motor oil, that the manufacturers were forced to take out due to EPA regulations!
