FIELD: petrochemical industry. ^ SUBSTANCE: invention refers to oil processing and petrochemical industry, particularly to a dispersing additive (a paraffin dispersant) improving operational characteristics of middle oil distillates (diesel fuels, stove fuels and others) at low temperatures, and it refers to a fuel composition containing dispersing additive. There is described a dispersing additive to a fuel on a hydrocarbon base, formed with middle oil distillates and representing the product of interaction of C16-C70 olefinating anhydride and aliphatic amino alcohol of a general formula: XN[(CH2)nOH]2, where X is hydrogen or C1-C5 aliphatic radical, and n is an integral number from 2 to 5 in kind of 40-70% solution in a hydrocarbon solvent. There is also described a fuel composition, containing a middle oil distillate, stripped within a temperature range of 150-450°C, a depressant at an amount of from 0.01 to 0.10 mas.% and an above described dispersing agent at an amount of 0.01-0.10 mas.% from the amount a middle oil distillate. ^ EFFECT: improvement of dispersive stability of paraffin hydrocarbons in a fuel at its storage under low temperature. ^ 3 cl, 2 tbl
