Zusammenfassung:A lubricant composition includes a base oil present in an amount of greater than 70 parts by weight per 100 parts by weight of the lubricant composition and an antioxidant. The antioxidant has the structure: wherein each X is independently CH or N, so long as at least one X is N. A is an electron donating group that (1) has an atom having at least one lone pair of electrons that is bonded directly to the aromatic ring or (2) is an aryl or alkyl group. Z is chosen from a hydrogen atom and an electron donating group that has an atom having at least one lone pair of electrons that is bonded directly to the aromatic ring or is an aryl or alkyl group.
