Abstract:
The present disclosure relates to methods for improving phosphorus retention and improving antiwear performance 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 about 100 ppmw phosphorus to about 1000 ppmw phosphorus, based on a total weight of the lubricating oil composition; and from about 10 ppmw zinc to about 1200 ppmw zinc, based on the total weight of the lubricating oil composition.
