Filled the DEF for the 1st time today. Took 4.2 gallons. Mileage was 5400. According to the calculator, that equates to just under 1300 miles per gallon. Dash info center said I had 470 miles left on ...
DEF seems like a very minor issue and expense. I do like having an actual gauge so I always know where I'm at vs waiting for a warning light to pop up unexpectedly.
