Over spring break in March, we went to Beavers Bend, Ok. That's was right at 1000 miles round trip. We were mostly on interstate hiways, so I decided to do some experimenting. I set it on 60 for about 50 miles, then 65, 70, and 75. I was watching the dash read-out the whole time to monitor the est. MPG. I find the computer to be right on with the hand calc mileage.
I found that there was only .5 MPG difference all the way across the board!! I found the engine to be most "happy" at about 72 MPH, so that's what I settled on for the rest of the trip.
BTW - my 5er weighs in loaded at 13,200, and I averaged 11.5 the whole trip.
