I just made a ~700 mile round trip this weekend. For the first half of the trip, I had my cruise set at 78 (actually about 74mph). I ended up getting about 32mpg. On the way back I kept it at 71-72mph (actually about 67mph). I got 34mpg that time. I have gotten even better than that, but there were way too many construction zones that I had to keep slowing down for and then speeding back up. :madfawk:
