Zinc DialkylDithiophosphate Lubricant Additives (ZDDP) is a zinc dialkyldithiophosphate lubricating oil additive of exceptionally high thermal and hydrolytic stability. It is generally used with detergent, dispersant and acid neutralizing additives in engine oils. This additive provides oxidation, copper-lead bearing corrosion and wear control in diesel and gasoline engines. It is particularly effective under the severe temperature and load conditions encountered in highly supercharged diesel engines.
