Pertaining to a gas oil additive for gas oil having ansulfur content of 0.2% by weight or less, characterized innthat the gas oil additive contains a compound containing anhydrocarbon group having 10 to 22 carbon atoms, amidengroup, and hydroxyl group on a carbon atom in β-positionnto nitrogen atom of the amide group; a gas oil compositionncontaining the gas oil additive; and a method of reducingnwear in a fuel injection pump or deterging a fuelninjection nozzle, each comprising using the gas oilncomposition. By using the gas oil composition of thenpresent invention, there can be exhibited effects innreducing wear of fuel pumps in a system using a gas oilnlikely to cause wear in fuel pumps, the gas oil having ansulfur content of 0.2% by weight or less, particularlyn0.05% by weight or less, and detergency effects of anninjection nozzle of diesel engines. |
