For me, the 11 with tow and 12.5 w/out tow (and empty tanks) are from miles driven divided by how much I put into the tank. Also, both numbers are ~99% freeway miles with no idle time on engine. And I try to keep it around 65 mph. Very rarely do I go faster than 70.
The 14.0 during a 3 hour trip was from the dash read-out (must have been going downhill the whole way or something.....)
And a tidbit on the DEF usage, I used 9.0 gallons over 3,400 miles. That's actual use, including idle time. Paid $2.69/gallon for the stuff at a Pilot station.
