A fuel additive concentrate comprises a friction modifier selected from the group consisting of an alkoxylated fatty amine, a fatty acid or derivative thereof, and mixture thereof; an alcohol; and a compatibilizer selected from the group consisting of a low molecular weight carboxylic acid or anhydride or derivative there of, glycol ether, alkylated phenol, and a mixtures thereof wherein the fuel additive concentrate remains fluid at −80 C or lower wherein the solvent has enough aromatic content to permit the fuel additive concentrate to be a fluid at minus 80 C. A fuel composition comprises fuel and the fuel additive concentrate. A method of operating a gasoline internal combustion engine comprises fueling the engine with the fuel composition and is effective in reducing fuel consumption.

A gasoline additive concentrate composition comprises a solvent, an alkoxylated fatty amine, and a partial ester having at least one free hydroxyl group and formed by reacting at least one fatty carboxylic acid and at least one polyhydric alcohol. A fuel composition comprises gasoline and the gasoline additive concentrate composition. A method of operating a gasoline internal combustion engine comprises fueling the engine with the fuel composition and is effective in reducing fuel consumption.

A concentrate composition contains (A) a fatty carboxylic acid based composition selected from (1) a fatty monocarboxylic acid, (2) an ester of (A)(1), (3) an amide of (A)(1), (4) an amine salt of (A)(1), and (5) a mixture thereof, and (B) a low temperature stability improving amount of a composition comprising one or more low temperature stability improving compositions. A fuel composition contains a major amount of a fuel and a minor amount of the concentrate composition. A method to improve the lubricity of a fuel composition containing a fuel comprises adding a lubricity improving amount of the concentrate composition to the fuel. The low temperature stability improving composition (B) is very effective in maintaining clarity, homogeneity and fluidity of a concentrate composition containing a fatty carboxylic acid based composition at low temperatures.
