ABSTRACT:
This invention relates to synergistic antiwear compositions comprising an organomolybdenum complex and an organic sulfuir compound selected from 2,5-dimercapto-1, 3,4-thiadiazole derivatives, bisdithiocarbamate esters, metal dithiocarbamates, metal phosphorodithioates and phosphorodithioate esters. The organomolybdenum complex is a reaction product prepared by reacting 1 mole fatty oil, 1.0 to 2.5 moles diethanolamine and a molybdenum source.
Lubricating compositions containing the synergistic compositions possess good antiwear properties and improved oxidation stability.
