Abstract: A lubricant composition is disclosed which comprises, a triglyceride oil lubricant and an oil soluble antimony compound as an antioxidant. Preferred antimony compounds are antimony dialkyldithiocarbamate and antimony dialkylphosphorodithioates.

Abstract: A lubricant composition is disclosed which comprises, a triglyceride oil lubricant and an oil soluble copper compound antioxidant. The oil soluble copper compounds are particularly effective antioxidants for triglycerides. The lubricant composition can include soluble zinc compounds which reduce wear and/or soluble antimony compounds which reduce wear and can function as adjuvant antioxidants reducing the amount of oil soluble copper required. Preferred zinc and antimony compounds are zinc dithiophosphate antiwear/antioxidant, and antimony dialkyldithiocarbamate antioxidant adjuvant.
