LUBRICATING OIL COMPOSITION CONTAINING SEDIMENT- REDUCING ADDITIVE

摘要

Lubricating oil compositions which contain polycarboxylic acid-glycol esters as friction modifiers in combination with hydrocarbon soluble alkenyl succinimide dispersants with reduced tendency toward formation of sediment upon storage through addition of small proportions of polyol or. polyol anhydride partial ester of a fatty acid or an ethoxylated fatty acid, amine or amide stabilizer. Glycerol oleates are preferred stabilizer additive.
