Abstract
An additive combination for distillate fuels and a fuel composition having improved cold flow properties. The additive combination is incorporated into a major proportion of distillate fuel and is comprised of an ethylene vinyl acetate isobutylene terpolymer in combination with one or more of a maleic anhydride .alpha.-olefin copolymer component, a polyimide component, and an alkyl phenol component each having one or more hydrocarbon substituents within specified carbon number ranges. Optionally, an ethylene vinyl acetate copolymer may also be incorporated as a component therein.
