Beschreibung
Zusammenfassung:	Novel gasoline compositions comprising gasoline and dissolved or dispersed therein small quantities of from about 0.5 to about 100 parts by weight of a driveability-enhancing fluorine-containing polymer per million parts of gasoline will, after carburetion in a multicylinder automobile engine, plate out a fluoropolymeric deposit on the interior surfaces of the intake manifold of the engine thereby establishing on the manifold metal surface a coating of low wettability by any hydrocarbon gasoline component, either aliphatic or aromatic, and significantly improving the driveability performance of the engine. The driveability-enhancing fluorine-containing polymers useful in the gasoline compositions of the invention are characterized in that they must (1) have a critical surface tension of
