A fuel additive that maintains optimum nozzle performance. Diesel fuel additive packages, diesel fuels containing the additives, and methods of operating an engine on the diesel fuels and additives. The fuel additives include: the reaction product of (a) a hydrocarbyl-substituted dicarboxylic acid or anhydride and (b) an amine compound of the formula, or a salt thereof, wherein R is selected from hydrogen and a hydrocarbyl group comprising from about 1 to about 15 carbon atoms , R 1 is selected from hydrogen and hydrocarbyl groups comprising about 1 to about 20 carbon atoms. The reaction product contains at least one aminotriazole group. Component (2) of the additive is a hydrocarbyl succinimide dispersant. The additives also include: (3) C 2 -C 10 alkyl alcohols; and (4) optional lubricant additives. In the additive, the weight ratio of component (1) to component (2) in the fuel ranges from about 1:3 to about 1:5. |
