"The composition of lubricating oil, additive concentrate for mixing with an oil viscosity of lubricant.The processes of lubrication of an internal combustion engine and for the preparation of a compound which has a core of Uncle - cubic, and use of an additive or additives.The invention relates to lubricating oil compositions comprising a major amount of an oil of lubricating viscosity and a smaller quantity of at least one compound containing a nu00facLeo tetranuclear heterometu00e1lico, preferably cubic, with greater preference uncle - cubic, with 1, 2 or 3 atoms of molybdenum, the others being atoms, Co, Cr, Cu, Ni, W, Mn, Zn or Fe.Preferably the ass, and connected in the same ligands capable of rendering the compound oil soluble or dispersible in oil.The lubricating oil formulated has improved properties of reduction of fiction and antiwear.
