PROBLEM TO BE SOLVED: To impart oxidation stability, storage stability, and thermal resistance stability to a bio-diesel fuel, to prevent the trouble caused by a gum-like substance formed by the oxidation polymerization of a fuel in an engine or a fuel tank, and to prevent the deterioration of automobile parts such as a fuel hose by using an antioxidant which can be easily and homogeneously mixed with a bio-diesel fuel being liquid at ordinary temperature and used in a cold district with less uncertainty. SOLUTION: A stabilized bio-diesel fuel is obtained by adding a specified quinoline-based or paraphenylenediamine-based compound to a bio-diesel fuel as an antioxidant. COPYRIGHT: (C)2009,JPO&INPIT
