[Problem] To produce a biodiesel fuel modifying agent of biodiesel fuel (BDF) such as methyl-esterified fuel. [Means for Resolution] A biodiesel fuel modifying agent characterized by ozone treatment of vegetable oil such as sunflower oil, rapeseed oil and soybean oil is provided. By adding this biodiesel fuel modifying agent to biodiesel fuel (BDF), the pour point of the biodiesel fuel can be decreased significantly. Therefore, the present invention makes the biodiesel fuel amenable for use even in cold regions etc. In addition, by adding the biodiesel fuel modifying agent according to the present invention to the biodiesel fuel, engine performance of a diesel engine, particularly, torque and horsepower at revolutions of low speed can be improved.
