Do you guys use any kind of additives in your fuel for the 6.7's? I use tranny fluid & 2 cycle oil in my 7.3. I've been weighing my options and considering a 15 350 drw. I've also read a lot of threads about radiators on these trucks. What's the big issue with these things? And if I decide to get one what do you guys recommend doing?
