Hope I’m not derailing the thread, but I have a question about DEF fluid itself. I bought a new 2019 f350 6.7. I haven’t driven it much in the last year, 3000 miles or so. Does the DEF fluid go bad? I have a full tank of the stuff, 7 gallons, and would hate to have a problem on the road with wonky DEF fluid. Been thinking about doing away ith the emissions stuff, too, but the truck runs great as is.
