Wow, my 5.0L in my signature gets about 15.5 to 16.0 in city driving, about 17.0 - 17.5 in mixed driving (agressive) and about 21 mpg in Expressway driving (passive). It also gets between 10.5 and 11.0 pulling my camper in the signature.
I'm very happy with the mileage, better than my 2010 F150 Screw 4WD 5.4L 3V w/6 speed auto, 2008 Sport Trac 4WD 4.6L 3V w/6 speed auto, 2005 Nissan Pathfinder 4WD 4.0 4V w/5 speed auto, 2004 Nissan Titan 4WD 5.6L 4V w/5 speed auto, and 2000 Nissan Xterra 4WD 3.1L w/4 speed auto. My 5.0L has better mpgs than any of the above trucks/SUVs.

Doing 62 mph on relatively flat highways I regularly record 24+ mpgs. S-Crew Eco w/SnugTop truck cap... I have 3.73 gears.
FYI, when on the turbos spool up, it because they are being told there is a need for TORQUE (not HP). 3.31 gears will not allow the engine to maintain anywhere near optimum torque range (rpm) on the freeway. I'm doing under 2,000 rpms on the freeway.
There is always the idea that you're driving more "fun" with the 3.73s as well. I just don't buy the bad mpg due to gears story.
It's all in how each of us drives our rigs!
