Abstract
Motor fuel composition comprising a mixture of hydrocarbons in the gasoline boiling range containing in combination a minor amount of a substituted asparagine containing the formula: ##STR1## in which R and R' each represent a secondary or tertiary alkyl or alkylene radical having from about 7 to about 20 carbon atoms and a minor amount of a carbonic acid ester having the formula: R'O(CH.sub.2 CH.sub.2 O).sub.n OCO--(RO).sub.x --CO(OCH.sub.2 CH.sub.2).sub.n OR' in which R is a divalent aliphatic hydrocarbon radical, containing 2 to 10 carbon atoms, R' is hydrogen or an aliphatic hydrocarbon radical containing 2 to 18 carbon atoms, x has a value from 1 to 4 and n has a value from 0 to 4.

A motor fuel composition comprising a mixture of hydrocarbons in a gasoline boiling range containing from about 0.001 to 5.0 weight percent of a substituted asparagine having the formula:
- ##STR4## in which R and R' each represent a secondary or a tertiary alkyl or alkylene radical having from about 7 to 20 carbon atoms and from about 0.01 to 0.05 volume percent of a carbonic acid ester having the formula:
- R'O(CH.sub.2 CH.sub.2 O).sub.n OCO--(RO).sub.x --CO(OCH.sub.2 CH.sub.2).sub.n OR'
- in which R is a divalent aliphatic hydrocarbon radical containing 2 to 3 carbon atoms, R' is hydrogen or an aliphatic hydrocarbon radical containing 2 to 18 carbon atoms, x has a value from 1 to 4 and n has a value from 0 to 4.
