I don't think anyone here bought theirs for good mpg. I've seen 7.5-8.0 mpg in a full tank of all-city driving, and heavy on the loud pedal. Worth It!
Best I've ever seen with mine is all-freeway at 70-75 mph for an entire 245 mile tank. That got me a bit over 17mpg. All flat terrain.
The best interim mpg (over a 50 mile stretch of freeway) was 18.8 mpg. But that's with optimal conditions and speeds.
Of course, we can cheat the numbers by the usual tricks, but what I've posted here are all real-world driving situations. No long downhills.
All while in performance mode, too. No Eco or cruise control use. Just how I regularly have it.
