Abstract

1. Fuel composition with improved flow at low temperatures, consisting of heating fuels or engine fuels with a boiling range of above 453 K and of ethylene copolymers, characterized in that the fuel composition contains 0.001 to 0.5 % by weight of an ethylene copolymer having a number-average means molecular weight of 500 to 5,000, preferably 1,000 to 3,500, and a comonomer content of 25 to 60 % by weight, which copolymer has 3 to 10 long-chain branches per 10**4 C atoms.
