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.
