When breaking in, how low does the fuel economy start?
I test drove a new 5.0 several times (same truck) and it was getting between 6 and 8 mpg, with about 30 miles on the truck. This truck didn't seem to have much oomph. It was pretty closer to my current 4.6 2V F150. I really felt that there was something wrong with this particular truck and didn't buy it. I'd like to hear from you 5.0 owners regarding where the mpg's started and how quickly it got better.

5.0 SCREW 3.73 with 3,900 miles avg 14.9 over the life of the truck about 60/40 city/highway. Cruising hwy at 65 I get a consistent 18.5-18.9 mpg. City is more like 13-14.

My 2011 5.0 4x4 STX gets a tad better mileage than my previous 2010 4.6 2-valve 4x2 STX did, so, even with more weight ... still get better mileage.
On the 2010 - 3.73 rearend gears are the same, no tow package, 4-speed automatic ... no other differences between the two trucks that I can think of ... except for my K&N CAI and Superchips 91 octane 'performance tune', I noticed no difference in gas mileage with these last two non-stock items.

I have 900 miles on mine right now. I have about 450 miles (2 weeks worth) on this tank. For this tank, I am averaging 18.6 with most of it rural driving at about 60mph coupled with some town driving. You really have to take everyones experiences with a grain of salt, because the conditions vary widely. You have to expect significant differences when comparing driving in hilly terrain with a lot of stop and go, or much big city driving to driving on flat ground with little stopping.
I can tell you that under the same conditions my old 2000 F150 with a 5.4 and a 3.73 rear end got 15.5-16MPG. The new 5.0 is MUCH more powerful than the old 5.4 and a fair bit more powerful than my current 2010 Chevy work truck with the 5.3. BTW all vehicles were/are 4x4's
When my truck is fully warmed up with the cruise set on about 58 and driving on flat ground, I get about 24 mpg.........but that is not real world, day to day mileage. It is purely optimum conditions.
I don't know what to expect after about 10K miles, but I would guess about a 1mpg increase.

FX4, 3.73s, 20s, camper shell...I average about 18.0mpg driving back and forth to work (hwy, interstate, pky overpasses, two lane roads, one mtn)...bought the truck with 500 miles on it and it got that mileage from day one...I have a very steady foot once I'm up to cruising speed but I like to hear the 5.0 when accelerating. I have driven it like granny would a few times and got 19mpg. Damn good for ~6,350lbs (truck, shell, gas, me) in my opinion...
