    Abstract: The invention provides a fuel oil composition comprising a fuel oil of animal or vegetable origin, in which a total of more than 6% by weight of palmitic acid methyl ester and stearic acid methyl ester are present, and, as an additive, A) at least one copolymer which contains 10-20 mol % of structural units of at least one vinyl ester and 80-90 mol % of structural units of ethylene, and B) at least one comb polymer containing structural units formed from B1) at least one olefin as monomer 1, which bears at least one C8-C18-alkyl radical on the olefinic double bond, and B2) at least one ethylenically unsaturated dicarboxylic acid as monomer 2, which bears at least one C8-C16-alkyl radical bonded via an amide and/or imide group, in which the parameter Q Q = ∑ i   w 1  i · n 1  i + ∑ j   w 2  j · n 2  j in which w1 is the molar proportion of the individual chain lengths n1 in the alkyl radicals of monomer 1, w2 is the molar proportion of the individual chain lengths n2 in the alkyl radicals of the amide and/or imide groups of monomer 2, n1 are the individual chain lengths in the alkyl radicals of monomer 1, n2 are the individual chain lengths in the alkyl radicals of the amide and/or imide groups of monomer 2, i is the serial variable for the chain lengths in the alkyl radicals of monomer 1, and j is the serial variable for the chain lengths in the alkyl radicals of the amide and/or imide groups of monomer 2, assumes values of from 23 to 27.

    Abstract: It has been discovered that less expensive, and in some cases synergistically effective anti-static additive blends may be added to hydrocarbon fuels to improve the conductivity thereof. The blend includes an anti-static amount of at least one hydrocarbon soluble copolymer of an alkylvinyl monomer and a cationic vinyl monomer and an anti-static amount of at least one hydrocarbon soluble polysulfone copolymer of at least one olefin and sulfur dioxide. Optional ingredients include polymeric polyamines and aryl sulfonic acids.
