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. |
