ABSTRACT OF THE DISCLOSURE The invention described herein relates to a multi- functional additive composition suitable for addition to distillate hydrocarbon fuels the major proportion of which distils within the gasoline distillation range, which additive composition comprises a mixture of (1) about 20 to about 250 parts by weight of a tertiary alkyl primary amino having a branched backbone and a total of 6 to 24 carbon atoms; and (2) about 100 to 650 parts by weight of an adipic acid ester comprising a Cl-C20 alkyl/alkyl phenoxy (alkyl of C4 to C9) polyethoxyethanol (containing 1 to 20 moles of ethylene oxide) ester of adipic acid. If desired, there may also be included in this composition from 5 to 100 parts by weight of a surface active alkyl ammonium carboxylate salt - ethoxylated alkyl phenol ester of trimex or dimex acid. These compositions of matter are useful in substantially reducing or even eliminating deposits which would otherwise form in the intake valves and ports and combustion chamber of an internal combustion engine, and in the carburetor.
