    Abstract: A composition comprising at least one fuel that is a diesel fuel, a biodiesel fuel, or combinations thereof and less than 100 ppm, less than 50 ppm (or less than 25 ppm, less than 10 ppm, 1 to 7 ppm, or 5 to 7 ppm) of an alkylene-coupled C10 to C60 (or C10 to C40, C14 to C32 or C24 to C28) alkylphenol; 25 to 500 ppm (or 50 to 500 ppm, or 150 to 450 ppm or 250 to 450 ppm, or 250 to 400 ppm) of a terpolymer; and 5 to 90 ppm, (or 10 to 70 ppm, to 60 ppm, or 10 to 55 ppm) 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 100 ppm, less than 50 ppm (or less than 25 ppm; less than 10 ppm, 1 to 7 ppm, or 5 to 7 ppm) of an alkylene-coupled C10 to C60 (or C10 to C40, C14 to C32 or C24 to C28) alkylphenol; 25 to 500 ppm (or 50 to 500 ppm, or 150 to 450 ppm or 250 to 450 ppm, or 250 to 400 ppm) of a terpolymer; and 5 to 90 ppm, (or 10 to 70 ppm, to 60 ppm, or 10 to 55 ppm) 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 3 wt % of an alkylene-coupled C10 to C60 (or C10 to C40, C14 to C32 or C24 to C28) alkylphenol; 10 to 50 wt % of a terpolymer; and 2 to 10 wt % of hydrocarbyl-substituted amine detergent having at least one tertiary amino group; and an optional solvent.
