Normally liquid fuel compositions containing N-substituted morpholines of the formula <IMAGE> wherein R' is a divalent organic radical of at least one to about 30 carbon atoms, R3 is a hydrogen atom or a hydrocarbyl, a hydroxy-substituted hydrocarbyl or a hydroxy hydrocarbyleneoxy-substituted hydrocarbyl radical of at least one carbon atom and R'' is a monovalent hydrocarbon radical of at least thirty carbon atoms, exhibit improved carburetor detergency and anti-icing properties. These fuels also inhibit deposit formation in the intake systems of internal combustion engines. Particularly preferred are gasolines containing morpholines wherein R' is 1,3-propylene, or poly(ethyleneoxy), R'' is a hydrocarbyl group of at least about forty carbon atoms and R3 is hydrogen. |
