My brother ordered a '99 F-350 4x4 DFW with the 4.10s and the 7.3 with automatic and it never got more than 11 or 12 mpg. Ran great but it burned a lot of diesel, I tried to get him to get 3.73s because he really didn't pull much. My Ram 3500 diesel I have now has 3.42s! Hardley ever gets much past 1800 rpms and still pulls better than anything I've ever owned.
I always got the wow look when the 7.3 diesel automatic guys asked me my milage was!
With the 6 speed manual, I typically got 18mpg avg empty!
I do not think I burned 3 tanks of fuel in the last 2 years now.
If I remember right, mine runs just under 2100rpm @ 70mph

That's pretty good for a Ford. I had an '01 Dodge with a 5.9 diesel 3/4 ton 4x4 with a 6spd that actually got in the 20's. Biggest mistake ever was getting rid of it! Probably be worth more than I paid for it now 15 years later.
I'll will not sell mine! She'll be 21 around Easter this year!
When I croak someone will probably send it to Barrett Jacksons! Lol
Hang onto it for sure! My friend said he saw an '03 Dodge diesel with low miles on it and they wanted $75,000 for it! Just incredible what people are trying to get out these trucks that are 20 years old.
