NOVELTY - Making biofuel blend involves blending petroleum distillate feedstock (F1) with selected amount of fatty acid alkyl ester-containing biofuels (B1); determining blend properties e.g. cloud point, low temperature flow; comparing blend properties with corresponding reference properties; and if blend properties correlate with reference properties within acceptable tolerance, then blending (F1) with selected amount of (B1), or if blend properties do not correlate with reference properties within acceptable tolerance, varying amount, composition, and/or number of (B1) and repeating above steps.    USE - For making a biofuel blend, particularly biodiesel blend (claimed).    ADVANTAGE - The method produces biofuel blends which has synergistic properties such as cloud point, conductivity, low temperature flow, cold filter plugging point, ignition quality, iodine value, and modified Rancimat value.    DETAILED DESCRIPTION - Making a biofuel blend, involves: either (a) blending a sample of a petroleum distillate feedstock (F1) with a selected volumetric percentage of at least two fatty acid alkyl ester-containing biofuels (B1); (b) determining at least one blend property selected from cloud point, low temperature flow, cold filter plugging point, oxidative stability, cetane number, ignition quality, and conductivity; (c) comparing at least one blend property with corresponding reference properties; and (d) (1) if at least one blend property correlate with the corresponding reference properties within an acceptable tolerance, blending the feedstock (F1) with the selected volumetric percentage of at least two biofuels (B1), or (2) if at least one blend properties do not correlate with the corresponding reference properties within the acceptable tolerance, varying the selected volumetric percentage, composition, and/or number of biofuels (B1) and repeating steps (a) to (c) until at least one blend properties correlate with the corresponding reference properties within the acceptable tolerance; or blending a petroleum distillate (75-85 vol.%) with fatty acid alkyl ester-containing biofuels (5-15 vol.%). An INDEPENDENT CLAIM is included for a biofuel blend comprising a petroleum distillate (75-85 vol.%) and fatty acid alkyl ester-containing biofuels (5-15 vol.%).
