About half this trip was on the interstate and I was doing 75 mph gps confirmed (~76.5 mph speedo). Then the other half was at 70 mph gps, on 4 lane rural highways. I got 39.8 mpg on the way west. I haven't refilled from coming home yet (the whole fuel gauge is blinking as I went to lunch today), but I suspect it was less than 41 mpg.
