Product Description
If your engine was designed prior to the 1990s, the non-roller lifters (flat-tappet cams) require ZDDP in the motor oil to avoid premature deterioration. Don’t let the lifters run metal-to-metal. Keep ZDDP, via ZDDPlus™, in your car’s motor oil. Add a 4 oz bottle of ZDDPlus™ to every 4- to 5-quart oil change. Just one bottle of ZDDPlus™ bring the current available “SM” oil (synthetic or conventional) back to the “SF” specifications.
- On bottle of ZDDPlus™ contains more ZDDP than two bottles of GM’s EOS.
- Safe, proven ZDDP EP agent takes the worry out of using new oil formulas in classic engines.
- Restores ZDDP to the optimum level which existed when your classic car or muscle car was new.
- Turns modern SM quality oil into the ideal oil for older cars, trucks, tractors, motorcycles, boats, etc.
- Compatible with ALL high-quality oils, standard or synthetic. You choose your own type of oil.
- Reduces cam and lifter wear in high-performance flat-tappet engines compared to a SM rated oil.
- One 4 oz. bottle of ZDDPlus™ per oil change with SM oil is more economical than 5 quarts of exotic oil.
- Treats 5 quarts of oil.
