<p>A gas oil according to the present invention comprises a gas oil fraction, and has a sulfur content not higher than 0.05 wt%, and either or both of (1) a content of bicyclic and higher aromatic hydrocarbons in a range of from 3.5 wt% to 15 wt%, bicyclic and higher aromatic hydrocarbons having at least one side-chain C3-11 alkyl group amounting to at least 80 wt% of said first-mentioned bicyclic and higher aromatic hydrocarbons, and (2) a content of nitrogen-containing heterocyclic compounds in a range of from 80 ppm to 500 ppm, nitrogen-containing heterocyclic compounds having at least one side-chain alkyl group accounting for at least 90 wt% of said first-mentioned nitrogen-containing heterocyclic compounds. The gas oil according to the present invention, as a diesel fuel, can impart anti-wearing properties by simply adjusting its components without the need for incorporation of an additive such as an anti-wearing agent. It does not cause wearing of a fuel injection pump, has excellent storage stability and can be furnished as an economical gas oil. It can also be furnished as a gas oil suited for use especially in cold districts.</p> |
