    Abstract: 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

    Abstract: Liquid hydrocarbons containing minor amounts of surface active, higher alkyl trimethyl ammonium salts are surprisingly resistant to forming water in oil emulsions and microbiological degradation. Detergent range alkyl trimethyl ammonium chlorides of limited hydrocarbon solubility are especially useful as antihaze and/or antimicrobial agents for heating oils. The water solubility of the new oil additives unexpectedly facilitates their bactericidal effectiveness. Furthermore, antihaze activity of these additives is uniquely unaffected by polar oligomeric additives such as cold flow improvers and detergents also present in the oil products.
