Abstract: An additive mixture as component of compositions of mineral oil as the main component and trace portions of an additive mixture contains the additive components a) ethylene-vinylester copolymers with molecular mass weight averages from 3000 to 50000 and an ethylene proportion of 50 to 90 mass %, and b) mixed esters of glycerine in which 50 to 80 mol % of the hydroxy groups are esterified with unsaturated C12-C40 monocarboxylic acids and 20 to 50 mol % of the hydroxy groups are esterified with partially imidated and/or partially esterified maleic anhydride copolymers, and/or c) partially and/or completely imidated copolymers consisting of maleic anhydride and α-methylstyrene with molecular mass number averages from 1500 to 15000 and at least one terminal group based on dimeric α-methyl styrene, and/or d) wax compositions based on natural starting materials of type d1) wax-like oligomeric esters based on glyceryl monostearate and dimeric acid and/or d2) wax esters with vaseline-like consistency, based on at least two different straight-chain and/or branched C14-C36-alcohols and dimeric acid whereby the content of the additive mixture in the mineral oil is 0.005 to 1 mass % and the mass proportion of the additive components a/b or a/c or a/d is in the range from 10:90 to 90:10, respectively. The mineral oil compositions are suitable as flowable media to be transported at low temperatures and as mineral oil fuels with high lubricity and flowability.
