A polymeric fuel additive, a method of making the additive, and a fuel containing the additive are disclosed. The additive is prepared by isothermally mixing an ethoxylated alcohol and an amide, wherein the ethoxylated alcohol comprises at least about 75 weight percent of at least one linear, straight-chain alcohol having a hydrocarbon chain length of about nine to about fifteen carbon atoms, and wherein the amide is formed by reacting an alcohol amine with an equimolar amount of an alkyl ester of a fatty acid or derivative. The alcohol/amide product is isothermally mixed with a substantially equimolar amount of an ethoxylated fatty acid having a hydrocarbon chain length of about nine to about fifteen carbon atoms to produce the polymeric additive. The inventive method is carried out with gentle mixing so as to avoid molecular degradation of the additive.
