Abstract: Embodiments of the invention provide a method of inhibiting precipitation of biodiesel fuel components. The method includes providing a biodiesel fuel composition; providing a copolymer comprising at least first and second polymer units, said first polymer units derived from a carboxylic acid anhydride and said second polymer units derived from an olefin; and blending said copolymer with the biodiesel fuel to form a treated fuel composition. Alternatively, instead of the copolymer, a dialkylene glycol additive can be provided. Embodiments of the invention provide a method of reducing the cold soak filter blocking tendency of a biodiesel fuel composition.
