摘要： A lubricating oil composition is provided comprising a major amount of an oil of lubricating viscosity and a minor amount of at least one trinuclear molybdenum compound. Preferably, the trinuclear molybdenum compound is selected from those compounds having the formula Mo3SkL4Qz and mixtures thereof in which L is a ligand having organo groups with a sufficient number of carbon atoms to render the compound soluble in the oil, k varies from 4 through 7, Q is selected from the group of compounds having lone pair electrons including water, amines, alcohols, phosphines, and ethers, and z ranges from 0 to 5. In general, the organo groups of the mono-anionic ligands will be the same although they may be different, and they preferably are selected from alkyl, aryl, substituted aryl, and ether groups. For example, when L is a dialkyldithiocarbamate or a dialkyldithiophosphate, the alkyl groups will have from about 1 to 30 carbon atoms.
