Abstract: The invention relates to the use of a mixture comprising (A) 5 to 95 wt % of at least one oil-soluble polar nitrogen compound that can interact with paraffin crystals in middle distillate fuels in the cold, and (B) 5 to 95 wt % of at least one oil-soluble aliphatic compound having alkyl or alkenyl chain having at least 8 carbon atoms that can be obtained from aliphatic mono or dicarboxylic acids having 4 to 300 carbon atoms or derivatives thereof having mono or polyamines or having alcohols for reducing the cloud point in middle distillate fuels that have a CP value of -8.0°C or lower before the addition of additives by at least 1.5°C compared to the middle distillate fuel without additives at a dosing of the mixture from 50 to 300 wt ppm, with simultaneous non-deterioration of the response characteristic for reducing the cold filter plugging point upon addition of cold flow improvers.

Abstract: The use of a mixture comprising (A) 5 to 95% by weight of at least one oil-soluble polar nitrogen compound which can interact with paraffin crystals in middle distillate fuels under cold conditions, and (B) 5 to 95% by weight of at least one oil-soluble aliphatic compound with an alkyl or alkenyl chain having at least 8 carbon atoms, obtainable from aliphatic mono-or dicarboxylic acids having 4 to 300 carbon atoms or derivatives thereof with mono-or polyamines or with alcohols, for lowering the cloud point in middle distillate fuels which, before the addition of additives, have a CP of -8.0°C or lower by at least 1.5°C compared to the unadditized middle distillate fuel at a dosage of the mixture of 50 to 300 ppm by weight, with no simultaneous deterioration in the response behavior for the lowering of the cold filter plugging point on addition of cold flow improvers.
