My answer is OFF. Drove 160 miles to family at the other end of the state, cruise control off most of the way, averaging 75mph for half the trip and 80+ for the other half, (with other miscellaneous speeds including triple digits, lol.) Saw 25.2mpg from this. Coming back, I had cruise set to 74-75 for 95% of the drive and I got 24.1mpg. It was me and a couple bags in the car, and the way down yesterday was pretty windy. Tonight on the way back, not so much.
