Abstract: Oil compositions comprising a lubricating oil, an amorphous ethylene-propylene copolymer viscosity index improver and a nalkylmethacrylate-containing polymeric pour depressant are substantially haze free if the number average molecular weight of the pour depressant is below about 120,000.
