FIELD: liquid fuel production. SUBSTANCE: invention relates to liquid fuel compositions and more specifically to those compositions prone to form paraffin at low temperatures. Composition based on mixture of biofuel and mineral fuel is distinguished by supplementarily having one or more additives modifying paraffin crystals and/or lowering flow temperature of fuels, additives being selected from the group including: oil-soluble copolymer of ethylene; comb-shaped polymer; polar nitrogen compound; compound in which at least one largely linear alkyl group is linked to nonpolymer organic residue to form at least one linear atomic chain including carbon atoms of mentioned alkyl groups and one or more non- terminal oxygen atoms. Additive concentrate is also described. EFFECT: increased usefulness of compositions. 18 cl, 5 tbl, 4 ex
