Abstract

A lubricating composition includes an oil of lubricating viscosity, an N-alkyl naphthylamine, and at least one ashless antioxidant selected from a diarylamine antioxidant, a phenolic antioxidant, and mixtures thereof. The lubricating composition has a phosphorus content of less than 0.15 weight percent. The combination of the N-alkyl naphthylamine and ashless antioxidant provides a beneficial effect on the basicity of the composition without negatively impacting seals performance.
