Abstract
Oil soluble combinations of (A) ethylene polymer or copolymer, (B) a second polymer having alkyl side chains of 6 to 30 carbon atoms, and derived from carboxylic acid esters and/or olefins, and (C) nitrogen compounds, such as amides, amine salts and ammonium salts, of carboxylic acids or anhydrides, are useful in improving the cold flow properties of distillate hydrocarbon fuel oils.
