Having a 5 gal DEF tank to begin with was pure stupidity. DEF sells mostly in 2.5 gal quantities. Even if you run it near perfect empty, you always have left over to stick in your garage and wait a few weeks to add in. (If you like topping off your tanks - which I do)
So isn't 7.5 gal the same issue with 2.5 gal quantities?
