<p>An additive for a gas oil having a sulfur content of not more than 0.2 % by weight, characterized by comprising a compound having a hydrocarbon radical with 10 to 22 carbon atoms, an amide group, and an amide group with a hydroxyl group located on a carbon atom at the β-position relative to the nitrogen atom of the amide group; a gas oil composition containing the gas oil additive; and a method for reducing the abrasion of a fuel injection pump or cleaning a fuel injection nozzle by using this composition. The use of this composition can advantageously reduce the abrasion of a fuel pump in a system using a gas oil having a sulfur content of not more thant 0.2 % by weight, particularly 0.05 % by weight, and being likely to cause the abrasion of the pump, and, at the same time, can offer the effect of cleaning an injection nozzle of a diesel engine.</p> |
