ABSTRACT:
The invention relates to lube oil compositions containing a major amount of a lube oil and a minor amount of at least one compound containing a heterometallic tetranuclear preferably cubane, more preferably thiocubane core having 1 to 3 molybdenum atoms and the remainder Co, Cr, Cu, Ni, W, Mn, and Fe. Preferred is Cu. Thiocubane cores are also preferred and these typically have the formula M.sub.4-y Mo.sub.y S.sub.4 L.sub.n Q.sub.z, wherein y is 1 to 3, n is 2 to 6 and z is 0 to 4. Additive concentrates of the compounds as well as the method of making the compositions are disclosed.
