ABSTRACT:
Oil compositions comprising a lubricating oil and an oil-soluble hydrocarbon polymeric viscosity index improver such as ethylene-propylene copolymers which contain an antihazing amount of an oil-soluble metal chelating compound having a nitrogen atom and a hydroxy group separated by 2 or 3 carbons and containing a total of 5 to 50 carbon atoms. The invention also relates to the process for preparing said compositions.
