    Is that calculated by taking your distance traveled between fill-ups divided by the gallons pumped in or is that just off of a display? Displays are never accurate. I can understand a 5 speed diesel getting better mileage than a gas truck but not that high. I have a 99 4.8 auto, just got 16.5 mpg (actually calculated, not from a display) driving 75 mph on a hilly highway.
