ABSTRACT OF THE DISCLOSURE A lubricant composition comprises as essential in- gredients a sulfur compound and an oil-soluble molybdenum compound, obtained by reacting one or more of hexavalent molybdenum compounds selected from the group consisting of molybdenum polyoxide, molybdic acid and alkali salts thereof, or a compound prepared by reaction of such a molybdenum com- pound and a reducing agent, wih an amino compound represented by the general formula: Image wherein R1, R2 and R3 which may be identical or different each individually represent a hydrogen atom or a hydrocarbon group having 1 to 30 carbon atoms. The lubricant additives comprising the novel molybdenum-amine complex and the sulfur- containing compound in combination exhibit excellent anti- oxidation, anti-wear and friction-reducing effects and are particularly excellent from the viewpoint of reduced metal corrosion.
