Wow, how do you guys get such great mileage? My '01 has averaged 14.1 (hand-calc) over the seven years and 57K I've owned it. It's job in life is to go to home depot and towing my 4Runner to Moab, which means several tall passes and 75mph speed limits.

That doesn't sound right at all. I as well have a 2wd and have seen as high as 24. Lowest I have gotten was 14.5 pulling my 24'TT and boat at the same time @ 70mph.
The only 7.3-powered Excursion I'd heard of that achieved that kind of mpg was very highly modified to do so, and driven with an egg on the accelerator. What mods have you done to yours to get that kind of mpg (especially towing)? I'm sorry, but I find it highly irregular, and I'm sure even Ford would like to study yours if it is actually achieving that kind of efficiency.
16 to 17 freeway, 11-12 when towing. I'm running 315's. No Mods. How do you guys use your overdrive? I only kick into od when 55+. what should I do to improve the economy to the numbers I'm seeing on this thread?

I get 15-17 around town depending on hills and force on the right foot. 21-25 on the highway (same as above) 19ish towing my 25 foot boat. I have a chip, modified intake and exhaust.
Mine probably averages around 18-19 hwy, but I also run about 78mph across the state and had 285's for tires...
That's exactly what I am getting but with stock tires. If I can keep it under 70 I can break 20mpg.

01 7.3 4X4. Mods in sig. As it is, i average 14-15 mpg in daily driving. I just returned from a trip to Gatlinburg TN and recorded 18 mpg with varying speeds from 60-80 mph. Those are overhead lie-ometer readings. I dont bother with really recording it as I never seem to get the same amount in the tank due to foaming. For that matter, it is so much better than my last X with the V10 that I do not really care what the actual number is. Right now my fuel gauge is a little above half with 340 miles (not corrected for tire change). I am sure the overhead is optimistic. The Nittos seem to have taken a chunk out of the mileage in both increased size and rolling resistance, but they look and perform good.
