The reaction products of hydrocarbyl-substituted amines with certain polyfunctional coupling agents, find use as detergents in distillate fuel compositions. The hydrocarbyl group is normally derived from natural sources or polyolefins of from about 420 to 10,000 average molecular weight. The polyfunctional coupling agents are certain polyhalides, polycarboxylic acids, and organic polyisocyanates.
