So, if Speeder's Excursion only got 17 on the road, then it was a) a 7.3 engine rather than the 6.0, b) had some mechanical issues, c) was driven by a lead foot and/or no one ever bothered to teach Speeder the fine art of driving to enhance fuel mileage, something that most people never learn. Another example of "tell me what you can't do, don't tell me what I can't do"!

Or maybe you just don't know how to accurately hand measure fuel consumption. That would be a much more likely scenario. Don't feel bad, a lot of people make this mistake on the internet.
As I stated above, Ive never owned an Excursion but have had several Power Stroke PU trucks, all 4x4s and 7.3 as well as 6.0. I found exactly zero difference in fuel mileage between the 2 engines and both were running 100%, showroom new compression with all latest dealer software, etc. As for the "fine art of driving to enhance fuel mileage...", there isn't one. Anyone w half a brain realizes that being smooth and avoiding excessive braking and accelerating results in better fuel mileage. I've calculated my mileage over thousands of miles, towing and empty including hours on the interstate w cruise control on at legal speeds. I always cancel the cruise for hill climbs, especially at altitude or anytime the engine is boosting up and under load. I drive for fuel mileage but do not hypermile, which I know how to do, btw.
