    Abstract: The disclosure describes reaction products useful as multipurpose fuel and motor oil additives which are reaction products of about equal molar portions of (1) an intermediate product produced by the condensation reaction between about equal molar portions of a compound selected from the group consisting of an alkenyl substituted succinic acid, an alkenyl substituted succinic anhydride and an alkenyl substituted succinimide or metal salt thereof, said compound having an average molecular weight from about 350 to about 1,000, and a second compound selected from the group consisting of ammonia gas, ammonium hydroxide and hydrazine, and (2) a third compound selected from the group consisting of basic metal compounds, compounds with displaceable halogens, acid halides, alkylene oxides, acid anhydrides, thio anhydrides, triethyl phosphite, boric acid and acrylonitrile. The intermediate product was itself found to be useful as a fuel and motor oil additive.
