Abstract: Lubricant compositions comprising (a) an oil of lubricating viscosity and (b) a phosphonate ester other than a zinc salt. The phosphonate ester may be the reaction product of (i) phosphonic acid or a monomeric ester thereof with (ii) a propanediol having hydroxy groups in both the 1 and 3 positions and one or more of the carbon atoms of the propyl units are substituted with one or more alkyl groups such that the total number of carbon atoms in the propanediol ranges from 4 to 12. The molar ratio of (i) to (ii) may be 0.9:1.1 to 1.1 to 0.9.

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.
