I was averaging around 80 mph using mid grade. If I was lucky I could get 350 miles to each tank. Traffic was cruising around 75 so I needed to be a step ahead. I just got my exhaust done the day before also. I went with a flowmaster 40 series with 4"tips 45 degrees from the bumper. A little cabin drone, but I like that. I didn't have a base line to go off of, but I still thought I would get better than that. lol Awe well, what can you say....its 381 hp that still gets better gpm's than my Sierra did!!
Doing 80mph I got 17.3mpg. in my 400 mile round trip. Doing 60mph I got 22.5 on a 360 mile trip.
