I would guess that increase to 22mpg would be under ideal condiotions. The increase would be about 2mpg from what they average now.... I would think Ford can do that.

that did not come out right...Although I have seen 20MPg we have never averaged 20mpg solo. We have averaged 18mpg solo..example westbound on the ohio and ind tpk and northbound on the fla tpk at 63/65 mph.If Ford has such a reflash a 2MPG increase would be good.

I would be thrilled to get mine up to 10mpg. Not gonna even expect to get the 12mpg my 6.0 did.
BTW,, my other truck was 2 WD, this one is 4WD, with the same 4.10 ratio. Should the 4x4 cost in fuel mileage? And if so how much?

, oops, I mean
Mallie
, it appears your truck is a job 1 build. For the job 2 and 3 trucks, Ford put a bigger air dam on the 4wd trucks to help with aerodynamics. Some guys have swapped to the new air dam and have seen 1 or more better mpg. To answer your question, 4wd adds a significant amount of weight and
height
to a truck, so there is a mileage hit for sure. If you have the stomach to void your warranty, the true mileage gains come from ditching that
My truck is a job 1 truck. If you are doing 10mpg solo on interstates or turnpikes at 63/65 mph there are serious problems with the truck or your driving habits. We also find it hard to beleive that a longer air dam will add any significant mpg. We are not happy that our Ford truck gets the worst MPG of the big three but it is not as bad as some experience here.

Mallie's truck has an enclosed service body on it that sticks up above the cab, so he will get worse mileage than a regular pick up. As for the air dam, ask yourself why Ford went to the trouble to change it. It sure isn't for looks!

I have the same truck & have averaged 16 to 16.5 solo. 2 grand on the RPM's , which is 63 MPH . Same terrain flat here in ohio.
I really don't know what my would get with the PU bed because it was drove straight to my shop from the dealer and swoped for my service bed. Total weight is 12,000. But I do have exact comparrison to the 6.0 that I replaced. Just seems like a loss from 12 to 8.3 should not be, espesically after all the hype about the 6.4 meeting all the low sulfer with more power and the same or better fuel millage. Someone forgot to tell the customer the truth.
Mallie I was trying to see the picts of your truck and see how close the enclosed body is to mine. Mine's an F550 4x4 with 4.30's at about 12-12.5K and I'm getting a solid 8-9 at best. You are lucky that you could get someone to drop your body on a F350. I couldn't get anyone to even consider it so ended up with the F550 because it was cheaper than the F450's.
Thanks for posting what you were getting on the 6.0. Since it seems that I got the same BS on milage you did and can't seem to find any rear options better than the 4.30's, I've sereiously begun to think about yanking the 6.4 and trying to find what it would take to drop the 6.0 in it and do away with all this BS stuck on the truck. Going from 15-19mpg to 8-9mpg is costing me about $10K extra in fuel this year alone.
I have a job3 F450 with 4.30s and it gets 15to16 mpg on the highway set at 1800 to 2000 rpms or 64 mph but with a trailer and pushing the wind not so good down to 8 or less set at 59
There's no way a program or reflash without removing the dpf is going to increase mileage.
On the contrary. Detroit Diesel has announced a reflash to improve fuel economy on their Series 60 engines. It promises up to 5% improvement. Our own testing showed their engines to give excellent fuel economy between regens, but they needed to regen every 250 miles. What they've done to improve the average fuel economy is run the engine on a high NOx/low soot model and increase the time between regens. This is how we do it as well as Cummins. We happen to be the current fuel economy leader for EPA 07 heavy heavy duty diesel engines. It can be done, question is,,, will it?
DSW,, what business are you in? My service bed is a Reading , just 8 foot long, 66 inches high and the truck fully loaded is 12k. The 350 carries it well. I think the 4.10 is the best ratio for our load.
I have a crane at my shop so I do my own bed changes with some help. I really can’t tell any difference in this 08 and the 05. But our business is in this lake area where access can be very steep gravel drives and some very bad dirt roads (mud in the winter). The 4x4 has been a real blessing. Just wish I had got it in the 05 with the 6.0. Never had any trouble with it. Course no trouble with this one except having to spend too much time pump side.

I happen to believe Ford has no choice but to find some improvement in the fuel economy or loose the lions share of the small truck business. There is too much at stake to not bet the farm on a solution.
In conservative terms, I think we all know it will never be what it was before.
