So I have a new to me 2003, F350 Dually with a 7.3L diesel.

My question is, does anyone use additives for the fuel? On our boat we use a fungicide to prevent growth here in the PNW. But that fuel sits for along periods of time. I burn through a tank of diesel in my truck about every 3 weeks. But I am also concerned about the injectors as I operate on roads instead of highways most of the time.

Thanks for the input.

 

i like archoil, and when i run out of that, and im waiting for more, i use diesel kleen.
