The main use of Zinc dithiophosphate (CAS NO.19210-06-1) is in anti-wear additives to lubricants such as greases, gear oils, and motor oils, which contain about 1%. For applications in oils for gasoline engines, zinc and phosphorus emissions could damage catalytic converters and have had their quantity reduced in standard formulations. Aftermarket additives are available. The same compounds serve also as corrosion inhibitors and antioxidants.
