Abstract: Improved fuel compositions with decreased tendency to form deposits in the carburetor and on "early fuel evaporation" heating elements, inlet valves and the like contain a normally liquid fuel (usually a hydrocarbon fuel), a carboxylic acid ester of lubricating viscosity, and an oil-soluble nitrogen-containing dispersant. The dispersant is characterized by the presence therein of a substantially saturated hydrocarbon-based radical having at least about 50 carbon atoms, and it is preferably a carboxylic dispersant (e.g., the reaction product of a polyisobutenyl succinic acid-producing compound with a polyethylene polyamine) or a Mannich-type dispersant (e.g., the reaction product of an alkyl phenol with formaldehyde and a polyethylene polyamine).

Abstract: Described herein are associative polymers capable of controlling a physical and/or chemical property of non-polar compositions that can be used when the non-polar composition is in a flow, and related compositions, methods and systems. Associative polymers herein described have a non-polar backbone with a longest span having a molecular weight that remains substantially unchanged under the flow conditions and functional groups presented at ends of the non-polar backbone, with a number of the functional groups presented at the ends of the non-polar backbone formed by associative functional groups capable of undergoing an associative interaction with another associative functional group with an association constant (k) such that the strength of each associative interaction is less than the strength of a covalent bond between atoms and in particular less than the strength of a covalent bond between backbone atoms.
