Abstract
Gasoline compositions having improved driveability comprise gasoline containing a minor amount of a compound having the formula ##STR1## WHEREIN R.sub.f is a perfluorinated radical selected from the group consisting of aliphatic C.sub.n F.sub.2n + 1 and cycloaliphatic C.sub.n F.sub.2n - 1, n is an integer from 1 - 18, q is 0 or an integer from 1 to 18, R is hydrogen or an alkyl radical having from 1 to 12 carbon atoms, R.sub.1 is an alkylene bridging radical having from 2 to 12 carbon atoms, m is 1 or 2, and X is chlorine, hydroxyl, --OMe (where Me is a metal), or a residual moiety of an active hydrogen-containing organic compound.

A gasoline composition comprising a minor proportion of gasoline and from about 60 parts per million N/V of gasoline of compound having the formula:
- ##STR3## wherein R.sub.f is a perfluorinated radical selected from the group consisting of aliphatic C.sub.n F.sub.2n+1 and cycloaliphatic C.sub.n F.sub.2n-1, n is an integer from 1 - 18, q is 0 or an integer from 1 to 18, R is hydrogen or an alkyl radical having from 1 to 12 carbon atoms, R.sub.1 is an alkylene bridging radical having from 2 to 12 carbon atoms, m is 1 or 2, and X is chlorine, hydroxyl, --OMe where Me is a metal, or a residual moiety of an active hydrogen-containing organic compound.
