The invention provides a fuel oil composition comprising a fuel oil of animal or vegetable origin and an additive comprising A) at least one copolymer of ethylene and 8 - 21 mol% of at least one acrylic or vinyl ester having a C1-C8-alkyl radical and B) at least one comb polymer containing structural units having C8-C16-alkyl 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 R = m1 . ~ w1i . n1i + m2 .cndot. ~ w2j . n2j +....... + mg . ~ w gp . n gp is the molar average 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 n1j, n1j..n2i, n2j...n gp are the chain lengths of the alkyl radicals i,j, .... p of the monomers B) 1 to g.
