Is he a real diesel mechanic or did he sleep in the Holiday Inn Express last night?
The pre 99 PSD's were a totally different animal and unfortunately many of the practices that worked well on those trucks have leached into the 99 and up trucks. Our injectors are very sensitive to junk like this. The rumor about the new fuel not having enough lubricant is bogus, but if you are worried add some Powerservice to each tank, that is what I use, but don't be adding motor oil, tranny fluid, Kerosene or anything else that somebody tells you too. You trucks injectors will thank you for it!!
If you want smoke ask Jody for his smoke tune, you'll get smoke!!! I am running his 120 race and she smokes like a freight train!!
