Davis, M E; Sung, R L

A clear stable motor fuel composition is described of the ''water-in-petroleum'' type microemulsion in which the average particle diameter of the dispersed phase is about 0.1 micron or smaller, the motor fuel composition comprising a mixture based on the final motor fuel composition of about 2.0 to 10.0 volume percent of an alcohol selected from the group consisting of methanol, ethanol, tertiary butyl alcohol, isopropanol, and mixtures thereof; about 0.10 to 0.50 weight percent water. About 0.10 to 3.0 weight percent of a nonionic adduct of aklylphenol and ethylene oxide surfactant has the structural Formula I, as follows: R(CH/sub 2/CH/sub 2/O)/sub x/H wherein: R is an alkylphenol group where the alkyl group has 9-24 carbon atoms; and x is an integer from 6-10.0; and the balance of the clear stable motor fuel composition comprises gasoline.
