ABSTRACT:
Normally liquid fuel compositions containing N-substituted morpholines of the formula ##STR1## wherein R' is a divalent organic radical of at least one to about 30 carbon atoms, R.sup.3 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 R.sup.3 is hydrogen.
