General 6.7 Discussion (2011-2016)
How far are you guys going on a tank of DEF? I read that we should get 5000 +/- per tank. I have 6500 miles on my 13, it was full when I bought it, I have added 5 gal since and it tells me 500 miles to empty. If 5000 miles per tank is true, I am hemorrhaging fluid.
