Fuel induction system of internal combustion engines are cleansed 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, especially when using a large amount of the detergent composition or when using the detergent composition with water intolerant gasolines, by inclusion of demulsifier containing an aryl sulfonate, a polyether glycol, and an oxyalkylated phenol formaldehyde resin. The concentrates of this invention also include one or more alcohols of about 4 to about 10 carbon atoms, an aromatic solvent, and a corrosion inhibitor. This invention also comprises gasolines containing these concentrates; the concentrate being present in a small amount that confers carburetor detergency properties to the gasoline.
