Ok, for those non-believers, here is a pic of my odo and gas gauge. This was with about 80% highway. The first half of the tank, my speed ranged from 70 to 80MPH. It was mostly hovering around the 74-75MPH area. The last tank, I kept the speed to 68-70MPH. Haven't filled it up yet, but I'm guessing it will be 16-16.5 gallons. At this pace, I could hit 400 miles no problem.
