I had to go to Lowe's Depot on Saturday, maybe 20 miles each way. On the way in I took the "small highway" as I call it to the kids. There was very little traffic and I worked it, got 74 and change mpg for the trip.
On the way back I was more pressed for time and it was a hot day, so I took the "big highway," ran it up to 65 and hit the cruise, then said what the hell and turned on the AC. I got 37 mpg for the return run.
