    • PROBLEM TO BE SOLVED: To provide a light oil composition which does not cause filter clogging at low temperature and satisfying practical performance and exhaust gas cleaning performance even when the light oil composition has a comparatively large deposition amount of wax at low temperature in areas and months where JIS No.2 light oil is desirably used with respect to a low sulfur light oil having ≤10 mass ppm sulfur content.
      SOLUTION: The light oil composition is produced by adding 10 to 1,000 mg/L low temperature fluidity enhancing agent to a mixed oil of a hydrogenated kerosene fraction refined from a crude oil and the like and a base material including a saturated hydrocarbon as a main component and has 750 to 850 kg/m
      3 density, ≤360°C 90% distillation temperature, ≥45°C flash point, a cetane value of 50 or more, ≤-5°C blockade point, ≥+5°C value of (a cloud point-the blockade point) and ≤10 mass ppm sulfur content.
