ZDDPlus Oil Additive - 17-9725

Sold Per: Each, Estimated Quantity Available: 65
Pricing: $12.99


We realize the words "oil additive" are likely to peg your B.S. meter, but hear us out. Zinc Dialkyl Dithio Phosphate (ZDDP) is a critical anti-wear ingredient in motor oil. It's being phased out because the small amount that sneaks into combustion chambers reduces the service life of catalytic converters, which of course is not an issue with vintage cars. For modern roller-tappet engines, the reduction of ZDDP is not of grave concern, but for flat-tappet engines such as those fitted to Jaguars, it is of critical importance. ZDDPlus restores this anti-wear agent and ensures proper lubrication. Sold per 4-ounce bottle, which will treat 4-5 quarts of oil. Please note that ZDDPlus cannot be used in cars equipped with catalytic converters. For more information, see www.zddplus.com
