ZDDPPlus Engine Oil Additive for Improved Performance

ZDDPlus is an oil supplement that contains very high concentrations of the well-known additive ZDDP (Zinc Dialkyl Dithiophosphate), which has been the primary EP (extreme pressure) ingredient in all quality motor oils for over 70 years. However, beginning in the late 1980s, the concentration has been greatly reduced as newer oil classifications have come on the market. ZDDPlus is the ONLY EP (Extreme Pressure) component which re-establishes the ZDDP levels that classic car engines were designed for, while allowing the car owner to use the base oil of their choice.

Under extreme conditions like a high performance motor, ZDDP reduces the tendency of parts to scuff or gall under heavy loads. While some off-the-shelf additives may have some ZDDP, the amount per bottle is small. ZDDPlus is not a typical oil additive, as it is compatible with all conventional and synthetic oils intended for automotive use. By adding a small 4 ounce bottle of it at every oil change, an adequate amount of Zinc and Phosphorus will continue to protect your engine.

ZDDPlus also alters bearing and journal surface characteristics to prevent metal to metal contact. This is especially important for older cars with flat tapped lifters-cam, which need the added zinc for protection. Simply empty the entire 4oz contents of the bottle into a 4 to 6 quart oil change to prevent metal-on-metal contact.

In conclusion, ZDDPlus is the ideal solution for pre 1989 and high performance engines, as it is compatible with both synthetic and conventional motor oils, and provides the necessary ZDDP levels to protect your engine under extreme conditions.
