Abstract:
A fuel composition for gasoline engines which keeps combustion chambers clean, does not contribute to octane requirement increase and even serves to decrease the octane requirements of an engine which has undergone octane requirement increase while operating on other fuel compositions. The fuel composition comprises a major amount of gasoline and at least 0. 4 weight percent of a hydrocarbyl poly(oxyalkylene) aminocarbamate.
