A composition comprising at least one fuel that is a diesel fuel, a biodiesel fuel, or combinations thereof and less than 100ppm, less than 50ppm (or less than 25ppm, less than 10ppm, 1 to 7ppm, or 5 to 7ppm) of an alkylene-coupled C10 to C60 (or C10 to C40, C14 to C32 or C24 to C28) alkylphenol; 25 to 500ppm (or 50 to 500ppm, or 150 to 450ppm or 250 to 450ppm, or 250 to 400ppm) of a terpolymer; and 5 to 90ppm, (or 10 to 70ppm, to 60ppm, or 10 to 55ppm) of hydrocarbyl-substituted amine detergent having at least one tertiary amino group. Methods of reducing the cold filter plugging point ("CFPP") of a fuel, said method comprising adding the following components: less than 100ppm, less than 50ppm (or less than 25ppm; less than 10ppm, 1 to 7ppm, or 5 to 7ppm) of an alkylene-coupled C10 to C60 (or C10 to C40, C14 to C32 or C24 to C28) alkylphenol; 25 to 500ppm (or 50 to 500ppm, or 150 to 450ppm or 250 to 450ppm, or 250 to 400ppm) of a terpolymer; and 5 to 90ppm, (or 10 to 70ppm, to 60ppm, or 10 to 55ppm) of hydrocarbyl-substituted amine detergent having at least one tertiary amino group. Uses of a fuel additive composition to reduce the cold filter plugging point ("CFPP") of a fuel, wherein the fuel additive composition comprises: 0.2 to 3wt% of an alkylene-coupled C10 to C60 (or C10 to C40, C14 to C32 or C24 to C28) alkylphenol; 10 to 50wt% of a terpolymer; and 2 to 10wt% of hydrocarbyl-substituted amine detergent having at least one tertiary amino group; and an optional solvent. |
