For those who haven’t read the whole thread, the gauge is a joke. Hand fill the tank yourself until you hear the DEF coming up the filler neck and your range will be substantially closer to expected. You should also reduce (sometimes increase, but let’s be real, most of us have added weight with mods and love putting the skinny pedal on the floor) the expected range by the same percentage as your average hand-calculated mpg compared to the EPA average...burn more fuel, spray more cat piss at the exhaust.
