Abstract: The invention relates to fuel oils comprising a larger proportion of middle distillates having a sulfur content of at most 350 ppm and an aromatics content of at most 22% by weight, and also a smaller proportion of at least one copolymer of ethylene and vinyl esters, said copolymer containing a) bivalent structural units derived from ethylene of the formula 1 nullCH2nullCH2nullnullnull(1) b) from 5 to 12 mol % of bivalent structural units of the formula 2 1 where R1 is saturated, branched C5-C18-alkyl, and c) from 4 to 13 mol % of bivalent structural units of the formula 3 2 and the sum of the molar proportions of structural units of the formulae 2 and 3 being between 12 and 16 mol %, to the corresponding polymers, and also to their use for improving the cold flow behavior of middle distillates having a sulfur content of at most 350 ppm and an aromatics content of at most 22% by weight.
