PROBLEM TO BE SOLVED: To enhance storage stability and at the same time, to prevent various troubles in a fuel tank, a fuel hose and an engine caused by oxidation deterioration during use by imparting oxidation stability to a bio-diesel fuel. SOLUTION: A stabilized bio-diesel fuel contains 100-2,000 ppm of a compound represented by formula (1) and 100-2,000 ppm of a compound represented by formula (2), so that the total amount of the compounds is at least 300 ppm or more. In the formula (1), R<SB>1</SB>represents a tertiary butyl group and R<SB>2</SB>represents 1C-4C alkyl group. In the formula (2), R<SB>3</SB>represents a 1C-8C alkyl group or a phenyl group, and R<SB>4</SB>represents 1C-6C alkyl group. COPYRIGHT: (C)2011,JPO&INPIT
