Abstract
A motor fuel composition comprising gasoline and benzyl polyamine of the formula ##EQU1## where Z is an alkyl- and hydroxy-substituted benzyl group wherein the alkyl group has 50-1000 carbon atoms and at least 60% of said alkyl group is para to the hydroxyl group, n is 2 to 3, R is hydrogen or Z, and the sum of a and b is 0 to 5, said polyamine being present in an amount sufficient to provide carburetor detergency. Also disclosed is a concentrated solution of said polyamine in a hydrocarbon solvent.
