To "piggyback" on pizzaguy's feedback, I averaged 26.5 mpg over 596.8 miles during the ToD (Tail of the Dragon) event last weekend in the NC mountains. I averaged 27.6 mpg driving up & back, running speeds between 70 & 80 mph. I averaged 24.0 mpg in the mountains, using the AutoStick shifting capabilities, which isn't bad considering all the curves & "twisties" we drove on. If you want to see some longer term results for an AutoStick, see the attached file.
