i agree with the post about running rich. it is most notable when it is cold. one time there was a cloudy puff of smoke and a raw gas smell.
my 05 e450 with 3k mi probably averages around 9 mpg mixed driving with 4.56 gears @ 8k lbs.

Most of the miles put on between central MN and south west MO. Approx 1600 mile round trips.

I get 11.5-13 mpg in my 2005 F350 V10 auto. It only has 3100 miles. Maybe when summer is over I'll get more. Then the bugs hitting the windshield and creating a counterforce will be diminished. Love this NEW beast, and don't give a damn about mileage. If so, I would have bought either a bug deflector or a Mini Morris!!!!
It's funny but in March 2005 I created a new thread titled $3.00/ gallon gasoline. I guess it's here in spades.

05 V10 10mpg solo, 9 towing, never more, never less.
Mine does seem to be excessivly rich, the tailpipe is always very sooty and it also smells rich.
I need to pick up a Wideband A/F gauge for my other vehicle, maybe when I do pick it up I will try it on the truck.

E450 V10 powered motorhome pulling a Jeep Wrangler, grossed at around 18,000 lbs. This is an '04 with the Torqshift tranny and 4:56 gears, and a little over 4K miles on it.
Running easy, backroads, 60mph max, easy on the starts, feathering the throttle I get 8.4--8.8 mpg.
Running interstate, staying with some traffic, 65-70 mph I get 6.4 mpg.
I am amazed at how this thing pulls well down to around 1700 rpm.

Loaded fuel efficiency depends too much on load, road and BSEG effect.
There is five years of this question asked at least once a week here and up in the SuperDuty and PSD forums.
There are a small amount of trucks that get 8-11 average and a few that claim 15-17 average.
Trust me the three V10 versions all get about 12.5MPG lifetime average. Slightly less if the BSEG effect includes a slight drool.

Is there any indication that the 3Vversion mated with the 5speed and 4.10's get less than their 2V 4 speed 3.73 versions? If this is the case than all 05+'s will get less maileage than pre 05's no?
It would make sense to me that the 05+'s WILL get less mileage, lower rear end ratio combined with more HP=less fuel efficiency.

My 05 3vV10 4.30:1 is averaging 2mpg less then my 01 2v 310hp with 3.73:1... The 05 is about 1000lbs heavier with fuel and that with the 4.30s is where I feel the loss comes in... in either event a 2v v10 or 3vV10 are significantly more effecient than any 460CI in a 800lb lighter truck. I was lucky to get 10 and most of the mixed driving was at 8mpg EMPTY!

99-04 (not sure about tires)
3.73's with 245/75-16 tires is 1899 rpm at 65 mph
05+
4.10's with 265/70-17 tires is 2012 rpm at 65 mph
4.30's with 265/70-17 tires is 2110 rpm at 65 mph
4.10's with 275/70-18 tires is 1918 rpm at 65 mph
4.30's with 275/70-18 tires is 2012 rpm at 65 mph
if option was available
05+
3.73's with 265/70-17 tires is 1830 rpm at 65 mph
3.73's with 275/70-18 tires is 1745 rpm at 65 mph
All rpm are calculated assuming a transmission with a .71 OD ratio

Here are some itema to help you calibrate your good idea post above... it is mathimaticaly wrong
The 4R100 and 5R110 both have a final OD ratio of 0.71:1
I am not certain that the ZF 6 speed is the same OD ratio
I never check at 65 but rather use 70mph
My 05 5R110w with 4.30:1 and 275x70x18 32.6" tires is at 2225rpm @70mph
If I put the tach dead on 2250rpm I am at 72mph
so I suspect your 1757 @65 calculation is way low
My 2001 V10 4R100 with 3.73:1 turning 265x70x16 31.2" was 2025rpm at 70mph if my feeble memory isn't having a CRS moment(grin)
