Abstract

The instant invention relates to a lubricant composition stabilized against the deleterious effects of heat and oxygen. The composition comprises a triglyceride oil or an oil which is an ester wherein unsaturation is present in either the alcohol moiety or the acid moiety and an effective stabilizing amount of either an N,N-disubstituted aminomethyl-1,2,4-triazole or an N,N-disubstituted aminomethylbenzotriazole; a higher alkyl substituted amide of dodecylene succinic acid; a phenolic antioxidant; and an aromatic amine antioxidant. Further additives can be added to these lubricant formulations.
