    Abstract: Mineral oil compositions with trace portions of additives contain as additive a comb polymer containing ester linkages, either based on a) ethylene-vinylester copolymers modified by hydroxy groups or glycidyl groups with molecular mass weight averages from 3000 to 50000 and an ethylene portion of 50 to 90 mass %, and b) partially imidated and/or partially esterified maleic anhydride copolymers, wherein in the comb polymer based on a) and b) the modified ethylene-vinylester copolymer component is connected by means of ester linkages to the partially imidated and/or partially esterified maleic anhydride copolymer component, or a comb polymer containing ester linkages based on c) ethylene-vinylester copolymers modified by acid and/or acid anhydride groups with molecular mass weight averages from 3000 to 50000 and an ethylene portion of 50 to 90 mass %, and d) polyalcohols partially esterified with C12-C40-monocarboxylic acids wherein in the comb polymer based on c) and d) the ethylene-vinylester copolymer component modified by acid and/or acid anhydride groups is connected by means of ester linkages with the polyalcohol component partially esterified with C12-C40-monocarboxylic acids. 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.

    Abstract: The present invention provides an additive for improving the lubricity of fuel oils having a maximum sulfur content of 0.035% by weight. The additive comprises A) at least one partial ester composed of a di- or polyhydric alcohol and unsaturated and optionally also saturated fatty acids whose carbon chain lengths are between 8 and 30 carbon atoms, at least 60% of the fatty acid radicals containing at least one double bond, and B) at least one alkylphenol-aldehyde resin, obtainable by the condensation of (i) at least one alkylphenol having at least one C6-C24-alkyl or C6-C24-alkenyl radical and (ii) at least one aldehyde or ketone, to a degree of condensation of between 2 and 50 alkylphenol units.
