This patent describes a product of reaction useful for improving the low temperature characteristics of hydrocarbyl distillate fuels produced from the reaction of (1) an amide derivative of a branched chain monocarboxylic acid having at least one tertiary amine group, (2) an epoxide having from 2 to about 18 carbon atoms and (3) an additional carboxylic acid selected from branched chain monocarboxylic acids or linear monocarboxylic acids. The reactants are reacted in substantially stoichiometric or equimolar amounts at temperatures ranging from about 50/sup 0/ to about 175/sup 0/C under autogenous pressure in 0.5 to about 3 hours or more.
