ABSTRACT OF THE DISCLOSURE Improved additives/detergents for lubricant and fuel compositions are obtained by condensing a hydroxyalkyl or hydroxyaryl compound with an amine compound having the structural formula Image (I) wherein R is independently hydrogen or C17 hydrocarbyl: R' is hydrogen, alkyl or NH2R"(NR")y-, wherein y is a number in the range from 1 to about 6 and R" is an alkylene group of 1 to about 10 carbon atoms; Y represents N or O; X is an alkylene group; A is hydrocarbyl; Z is alkylene of 1 to about 10 carbon atoms, oxyalkylene of 1 to about 10 carbon atoms or a 5- or 6-membered heterocyclic ring containing at least one nitrogen atom; x is a number in the range from 1 to about 10; u is an integer greater than 1; and n is 0 or 1 dependent on m and q wherein q is 0 or 1 and m is 2 or 3. The condensates according to the present invention are produced by the acid catalyzed condensation of the amine reactant with the hydroxy reactant.
