Last weekend my wife drove out of state for the day and I forgot to take the Yakima roof rack off the top we use for bikes. When she got back I looked at the dash and saw 32.4 MPG. Last month we took a vacation of the same distance and on the way home, 380 miles, we averaged 47 MPG on mostly old 2 lane hwy at 60 MPH. I usually get 41-45MPG on a tank for 60% suburban driving according to the computer. I've got about 6000 miles on it since June 6th.
