ABSTRACT:
This invention relates to oil soluble additives particularly useful in lubricating oil compositions, and to concentrates or lubricating compositions containing these additives. The additives are various metal salts of mono- or dicarboxylic acids, anhydrides, esters, etc., which have been substituted with a high molecular weight hydrocarbon group, and derivatives thereof. The high molecular weight hydrocarbon group has a number average-molecular weight (M.sub.n) of greater than about 900. The metal salt additives are especially useful in combination with certain grafted ethylene-olefin copolymers or copolymers of 4-vinyl pyridine and esters of aliphatic mono-, di- or polycarboxylic acids as viscosifying agents.
