Zusammenfassung:	PURPOSE: Lubricant compositions and methods of making them, are provided. CONSTITUTION: A lubricating oil composition, comprises: a major amount of an oil of lubricating viscosity to which is added a minor amount of an additive having the formula M4-y Moy S4 Ln Qz and mixtures thereof, wherein M is a metal selected from Cr, Mn, Fe, Co, Ni, Cu, and W, L is independently selected organic groups selected from dithiophosphates, thioxanthates, phosphates, dithiocarbamates, thiophosphates and xanthates, having a sufficient number of carbon atoms to render the additive soluble or dispersible in the oil, and Q is a neutral electron donating compound, y is 1 to 3, n is 2 to 6, and z is zero to 4, and the L provide a total charge sufficient to neutralize the charge on the M4-y Moy S4 core.
