Abstract
Described are low ash, low phosphorus motor oils having improved oxidation stability as a result of the addition thereto of synergistic amounts of a dialkyldiphenylamine antioxidant and of a sulfurized polyolefin. The synergism between the two additives compensates for the decreased amounts of phosphorus in the form of zinc dithiophosphate such that the oils retain an SE quality rating.
