摘要： 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, wherein Y is CRR', NR", PR", S, or O, each R, R' and R" is independently H, alkyl or aryl, and R" is alkyl, aryl, alkoxy or aryloxy. Each A is independently an electron donating group. The electron donating group (1) has an atom having at least one lone pair of electrons that is bonded directly to the aromatic ring, (2) is an aryl or alkyl group, or (3) is a hydrogen atom.

摘要： Provided are a lubricating engine oil and a method of improving nitrile seal compatibility with a lubricating oil in an engine lubricated with such lubricating oil. The method includes using as the lubricating oil a formulated oil comprising a lubricating oil base stock as a major component and one or more additives selected from the group consisting of (i) a sulfone, sulfolane, or derivative thereof; (ii) a borate ester, boron amide, or mixtures thereof; (iii) a sulfurized olefin; (iv) a thiadiazole or derivative thereof; and (v) a succinic anhydride or derivative thereof, as a minor component. Nitrile seal compatibility is improved as compared to nitrile seal compatibility achieved using a lubricating oil containing a minor component other than the one or more additives.
