<p>A gas oil composition which contains a low environmental load type gas oil base prepared by using, as the raw material, either an animal or vegetable oil or fat or hydrocarbons containing triglycerides resulting from an animal or vegetable oil or fat and which is excellent in life cycle CO2 emission characteristics, oxidation resistance and influence on members, specifically, a gas oil composition which is produced by blending 5 to 90vol% of a low environmental load type gas oil base prepared by subjecting an oil to be treated, which is obtained by mixing an animal or vegetable oil or fat and/or a component resulting from an animal or vegetable oil or fat with a sulfur-containing hydrocarbon compound in such amounts as to give a sulfur content of 1ppm to 2% by mass, to hydrotreating in the presence of hydrogen under prescribed conditions in two stages with 95 to 10vol% of a hydrotreated oil prepared from crude oil or the like and adding a predetermined amount of a low-temperature fluidity improver to the obtained blend and of which the 90% distillation temperature, flash point, cetane number, cold filter plugging point, sulfur content, oxygen content, triglyceride content, fatty acid alkyl ester content, total acid value, and acid value increase after oxidation resistance test fall within specific ranges respectively.</p> |
