I absolutely recommend an additive, todays fuel is garbage no matter where it comes from. There is significantly less lubricity than older fuels. The ultra low sulfur diesel in my opinion is suspect enough that when i forgot to add the additive in fill-ups, about the next tank I notice how it doesnt run as smooth. For $3 extra each fill up, I know that my fuel pump and injectors are better off with then without. Cheap preventative measure. I use Schaeffers diesel treat and have used diesel kleen. Stanadyne im sure is good too, do your research.
