Lubricating oil containing a nickel alkoxyalkylxanthate, a dixanthogen, and zinc dialkyldithiophosphate

摘要

The addition of a metal alkoxyalkylxanthate, a dixanthogen, and a metal thiophosphate to a lubricating oil results in a synergistic improvement in the antiwear performance of the oil. Nickel ethoxyethylxanthate, diethoxyethyl dixanthogen, and zinc dialkyldithiophosphate are particularly preferred additives.
