4-25-2015. For anyone who is interested - I just posted an update on page 3 with my latest mpg after just refilling the DEF tank yesterday. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++...
I added 150 miles to the odo reading today and the gague is still just over 3/4. I have not added DEF since purchase. Dealer must have actually filled the tank.
