A fuel composition that while maintaining the excellent exhaust gas performance of Fischer Tropsch synthetic oil, realizes suppressing of mileage deterioration. There is provided a fuel composition of 45°C or higher flash point comprising a Fischer Tropsch synthetic oil containing 10 to 30 vol.%, based on the whole amount of the composition, of petroleum hydrocarbon mixture (A) having the properties of (1) 15°C density: 800 to 900 Kg/m3, (2) 10 vol.% distillation temperature (T10): 150°to 200°C, (3) 97 vol.% distillation temperature (T97): 270°C or below, (4) aromatic content: 40 to 70 vol.% and (5) sulfur content: 30 mass ppm or less. |
