I have honesty got 14mpg with my 93 460 ZF with 3.55 gears empty, That was 70+mph in the summer. Normally mixed driving is about 10-12mpg. Been looking at getting a diesel but the price of diesel is higher and added maintence probably a break even deal. A guy I work with has a 99 super duty with the zf6speed. He says he gets 19-20mpg unloaded. I am looking at a 85 f250 with 6.9l this afternoon for $2500 the owner said it got around 16mpg 18 was the best.

Well, I had a 7.3L naturally aspirated IDI with a 5 speed Long bed Extended Cab 4X4. I got, depending how it was driven, 16 to 20 around town. That is NOT city driving. I have a 6,0L now, and summer I get 20-21. Winter is down near 17. If you are getting on it, you will get lousy milage. Drive it easy, and it will reward you.

I have a 94 F250 4x4 super cab long bed with a IDI TD, E40D, 4.10 gears 235/85/16 tires at 80psi. The truck had 122k miles at the start of the trip and a bit over 123k at the end. I drove it back from FL and tested the mileage. Here is what I got...the truck was basically empty...one motorcycle in the bed and pulling a jet ski on a trailer.

Cruise Control set at 70mph (about 2250rpm) --> 13mpg

Cruise Control set at 60mph (about 2000rpm) --> 16.5mpg

Cruise Control set at 55mph (about 1800rpm) --> 21.3mpg

All of the above figures are indicated (as opposed to GPS confirmed etc) and were obtained in very similar moderately hilly conditions on the same day and were tested for more than 100 miles.
