PROBLEM TO BE SOLVED: To provide a fuel oil composition excellent in low-temperature performance without performing test production for evaluating whether low-temperature performance is excellent or not by tentatively blending different fuel oil base materials. SOLUTION: The fuel oil composition is provided of which a P value, represented by formula 1, of the fuel oil composition predicted after blending two or more different fuel oil base materials is in the range of -3 to 3, and a low-temperature fluidity index S represented by formula 2 is 1.3 or more. S=-0.211×nC12+0.56×nC13-0.137×nC14+0.177×nC15+0.244×nC16+0.083×nC17-0.117×nC18-0.09×nC19+0.409×nC20-0.645×nC21+ 0.537×nC22-1.159×nC23-1.168×nC24+0.32×nC25+6.482×nC26-5.555×nC27-0.00356×(forth moment)+0.00643×Mw-0.841 (formula 2).
