As was stated earlier, one DEF option is to use the big-truck pumps at a truck stop. The fuel pumps probably won't work too well for you because of their outlet size and the high speed but the DEF pump should work. I never had any problems putting DEF into the big truck since the early (2011) days when DEF pumps were still rare and we had to carry our own. Truck stop DEF has a high usage rate so should be pretty good. For those of you "LUCKY" enough to need DEF, the DEF pump nozzles are pretty small so they should work for you and the fluid should be cheaper. Luckily my Dodge/Cummins is a 1994. I don't know of quality differences in various DEF brands but the basic Urea/DIWater is basically the same.
