Abstract:
A lubricating composition comprising an oil of lubricating viscosity and about 0.1 to 10.0 percent by weight of a synergistic anti wear composition consisting of(a) an organomolybdenum complex prepared by reacting about 1 mole fatty oil, about 1.0 to 2.5 moles diethanolamine and a molybdenum source sufficient to yield about 0.1 to 12.0 percent of molybdenum based on the weight of the complex and (b) a dithiocarbamate of the formula wherein R4 and R5 represent alkyl groups having 1 to 8 carbon atoms, M is zinc, and n is the valence of M, and wherein the ratio of the molybdenum complex to the dithiocarbamate is about 1:2 to about 5:1.
