Abstract
Polymerizable (that is, e.g., monomeric) polyfluorinated compounds, when added to a lubricant or to a liquid hydrocarbon fuel, as for example gasoline, will cause a reduction in fuel consumption. Reduced fuel consumption may also be realized for long periods from pistons and/or cylinder walls so coated with one or more of the polymerizable compounds.
Claims10
A method for decreasing fuel consumption in an internal combustion engine by adding to the lubricating oil or liquid hydrocarbon fuel used therein a sufficient amount of a polymerizable polyfluoro monomer compound of the formula ##STR4## wherein R is a C.sub.3 to C.sub.17 aliphatic hydrocarbon group containing from 5 to 35 fluoride groups, R' is hydrogen or a C.sub.1 -C.sub.3 hydrocarbyl group and R" is hydrogen or a C.sub.1 -C.sub.18 hydrocarbyl group and polymerizing said monomer during engine operation to form an amount of a polymer thereof to effect a reduction in fuel consumption of said engine.
