An additive for improving the low temperature fluidity of a fuel oil is provided. A A) of ethylene, propene and at least one ethylenically least one terpolymer consisting of an unsaturated ester, however this terpolymer, i) C 1 ~C 3 at least one ethylenically unsaturated having an alkyl group Containing structural units derived from esters in a proportion of 6.0 to 12.0 mol%, ii) containing 0.5 to 4.0 methyl groups derived from propene per 100 aliphatic carbon atoms, iii) less than 8.0 methyl groups derived from chain ends per 100 CH 2 groups; and B1) a copolymer of ethylene and an ethylenically unsaturated compound, provided that the ethylenic unsaturation of this copolymer The content of the compound is at least 2 mol% higher than the content of the ethylenically unsaturated ester in the terpolymer as defined in A); B2 Comb polymers, additive mixture comprising; and B3) B1) and B2) and mixtures.
