- 2015 Mustang GT
I say you might be seeing it but you are not getting it! Calculate by hand a few tank fulls. My Mustang GT overstates an average of 1.1 MPG per tank full. My 2015 Ford Escape overstates 2.2MPG per tank full. The MKZ overstates 1.7 MPG per tank full. These are all average's over several thousand miles.I regularly see 28+ mpg on all highway trips at 75 mph cruise. Yesterday it touched 30.0 (indicated) before I had to turn off. GT with 3.31 axle. I'd expect 26ish for a PP GT.
Everybody I know that has calculated their mileage compared to the computer has come up with a lower average.
My C6 Corvette was off by 1.7 mpg over a 7200 mile span.
