А-22 is а zinc dialkyl dithiophosphate lubricating oil additive of good thermal and hydrolytic stability. A-22 is generally used with detergent, dispersant and acid neutralizing additives in engine oils. This additive provides control of oxidation, copper-lead bearing corrosion and wear in diesel and gasoline engines. It is particularly effective under the severe temperature and load conditions encountered in highly supercharged diesel engines.
