A gas oil composition which contains an environmentally friendly gas oil base produced from, as raw materials, an animal/vegetable fat and triglyceride-containing hydrocarbons which are an ingredient derived from an animal/vegetable fat. It is excellent in life-cycle CO2 emission characteristics, fuel efficiency, and oxidative stability and in member stability. The gas oil composition contains: 5-50 mass% saturated chain hydrocarbons produced by contacting an animal/vegetable fat and/or a feed oil comprising an ingredient derived from an animal/vegetable fat with a given porous inorganic oxide and a catalyst containing one or more metals selected among the elements in Groups 6A and 8 of the periodic table and deposited on the porous inorganic oxide, under the conditions of a hydrogen pressure of 2-13 MPa, liquid space velocity of 0.1-3.0 h-1, hydrogen/oil ratio of 150-1,500 NL/L, and reaction temperature of 150-480°C; and 5-30 mass% catalytically-cracked gas oil base obtained by hydrotreating a gas oil fraction obtained with a catalytic cracking apparatus. The composition has a cetane number of 54 or larger and an aromatic content of 17 vol.% or higher. |
