Abstract

Abstract Fuel induction systems of internal combustion engines are cleaned by operating the engine on a gasoline containing a detergent amount of the condensation product of phenol and preferably a high molecular weight alkylphenol, an aldehyde and an amine having a H-N< group. Effectiveness is improved by inclusion of a mineral polyolefin having an average molecular weight of from about 300-2000. The condensation product is also effective in other distillate fuels.
