    Abstract: Provided is a mixture containing: (a) a polar oil-soluble nitrogen compounds which is capable of sufficiently dispersing paraffin crystals precipitated out under cold conditions in a fuel and is a reaction product formed from reacting a poly(C2- to C20-carboxylic acid), which has at least one tertiary amino group, with a primary or secondary amine; (b) an oil-soluble acid amide reaction product formed from reacting a polyamide, which has from 2 to 1000 carbon atoms, with a C8- to C30-fatty acid or fatty acid-like compound, which has a free carboxyl group; and (c) an oil-soluble reaction product formed from reacting an α,β-dicarboxylic acid, which has from 4 to 300 carbon atoms, or a derivatives thereof, with a primary alkylamine, wherein the sum of components (a) to (c) constitute 100 wt. % of the mixture. The mixture is suitable as a paraffin dispersant in fuels, especially those having a biodiesel content.
