Oil-soluble aliphatic copolymer having the property of a nucleator for wax crystallization e.g., ethylenevinyl acetate copolymers having a number average molecular weight within the range of 500-50,000, in combination with an oil-soluble derivative of an aromatic copolymer are useful in improving the cold flow properties of distillate hydrocarbon oils.
