Lubricating compositions for a hybrid engine

A method for reducing wear in an internal combustion engine of a hybrid vehicle comprising lubricating the internal combustion engine of the hybrid vehicle with a lubricating oil composition comprising:

• greater than 50 wt. % of a base oil of lubricating viscosity;
• and
• an amount of one or more zinc dialkyl dithiophosphate compound(s) sufficient to provide:
• from 550 ppmw phosphorus to 710 ppmw phosphorus, based on a total weight of the lubricating oil composition, and
• from 200 ppmw zinc to 821 ppmw zinc, based on the total weight of the lubricating oil composition;
• and
• wherein the one or more zinc dialkyl dithiophosphate compounds are derived from 100 mole % of one or more primary alkyl alcohol(s),
• the one or more zinc dialkyl dithiophosphate compound(s) has a zinc to phosphorus molar ratio of at least 1.20,
• the lubricating oil composition further comprises one or more components selected from the group consisting of succinimide dispersant(s), borated succinimide dispersant(s), organic friction modifier(s), molybdenum-containing compound(s), calcium sulfonate detergent(s), antioxidant(s), antifoam agent(s), pour point depressant(s), and viscosity index improver(s), and
• the internal combustion engine of the hybrid vehicle is operated at a temperature of 100° C. or less.
