I look forward to getting 400-mile tanks again.
I did cut it pretty close yesterday, but there were still a few gallons left in the tank.
One of these days when I'm carrying a gas can I'll run it completely out to see where that line really is.
Like I said, it's the extreme high end. I wasn't going downhill, though -- it was mild rolling interstate at moderate speeds (65-70mph). Any significant change in speed, altitude or incline and that would not be a sustainable number. The key I've found is really making sure it kicks down --- with a hair too much throttle (or CC) it'll sit at 2100rpms versus 1750 or so. It's a "hidden kickdown" if that makes any sense. I found this would cost me 1-2 mpg.
Driving from AZ to WA last week, towing 6,000lbs, I got 13.5 mpg over 1800 miles. That's as good or better than most if not all full-size gas V8 pickups.
I agree, 400 mi tanks are the real prize.
