ZDDPlus - The original Zinc oil additive, dedicated to Protecting Your Classic, High Performance, Racing, and Industrial Engines!

Big Notice!!!!!

ZDDPlus Central is moving! That's right, ZDDPlus Central is moving West, right into the middle of hot rod/drag racing/car club territory! On Wednesday, May 23rd ZDDPlus Central will cease operations at its Wyoming address and resume operations on Tuesday, May 29th in Mcminnville Oregon!

We've decided that ZDDPlus is becoming so popular that we just have to be in the middle of car territory. Woodburn Raceway in Woodburn Oregon will become our home base and we'll be attending events up and down the entire West Coast!

Shipping to all of our valued on-line customers will still take just 2 or 3 days transit time, ensuring your supply of ZDDPlus is just a keystroke away.

We will not be shipping for a few days next week, but rest assured we've got this move planned down to the minute and will resume our shipping on Tuesday the 29th.

Thanks to all or our loyal customers we're taking the next step! Come along for the ride!

For more than 70 years ZDDP (Zinc Dialkyl Dithio Phosphate, containing Zinc and Phosphorus) was a mainstay of motor oil, providing trouble-free engine protection. The E.P.A. has now forced most ZDDP from domestic motor oil, including diesel oils. This lack of zinc and phosphorus is most severe in the just-released 'SN' (ILSAC GF-5) rated oils.

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, mentioned in one oil manufacturer's advertising, also 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!
