The invention provides a fuel oil composition F) comprising F1) a fuel oil of mineral origin and F2) a fuel oil of vegetable and/or animal origin, and, as a cold additive, t he constituents A) at least one copolymer composed of ethylene and 8-21 mol% of at least o ne acrylic or vinyl ester having a C1-C18-alkyl radical and B) at least one comb polymer containing structural units having C8-C16-alk yl radicals, the structural units being selected from C8-C16-alkyl (meth)acrylates, C8-C16-alkyl vinyl esters, C8-C16-alkyl vinyl ethers, C8-C16- alkyl(meth)acrylamides, C8-C16-alkyl allyl ethers and C8-C16-diketenes, where the sum R (see above formula) of the molar averages of the carbon chain length distributions in the alkyl radicals of the monomers B) is from 11.0 to 14.0, where m1, m2, ... m g are the molar fractions of the abovementioned monomers B) in the polymer, and the sum of the molar fractions m1 to m g = 1, w1i, w1j..w2i, w2j...w gp are the proportions by weight of the individual chain lengths i, j, p of the alkyl radicals of the different monomers B) 1 to g, and n1i, n1j..n2i, n2j...n gp are the chain lengths of the alkyl radicals i, j, .... p of the monomers B) 1 to g.
