Looking at buying a used Superduty here eventually. Can't afford a Diesel. Does anyone know what the average MPG for the 5.4 and the V10? I had a buddy that had a 99' CrewCab 4x4 with a V10 and he was getting about 9 MPG. Anyone doing better than this with a V10? Is there any upgrades without spending thousands to get better gas mileage?

to make a long story short must depend on truck and driver

I get 13mpg with a 2V 5.4L
You will get maybe a little less with a V10 Empty
If you are hauling a lot you may get little better milage with a V10.
Get what you want and what you need.
Gas milage is going to suck no matter what. Rememebr we don't by superduties for gas mileage.
If you do a lot of hauling also think about getting a truck with 4.10 gears insted of 3.73's.

There are a few ways of looking at this, but the short answer is don't get a Super Duty if your main concern is fuel mileage.
Longer answer is, my fuel consumption didn't go up from my last truck, which was a 1995 F-150 Super Cab 4x4 with a 302 V-8, automatic and 3.55 gears. My old truck was rated at 6500 pounds towing, but anything over 4000 pounds felt unsafe. My new truck is rated at 9200 pounds for towing and feels great at that limit.
Mine gets about 16 MPG for mostly highway driving. You may or may not be able to use that figure, as this is a 3V 5.4. (See sig) 2V engines may get better mileage. A few guys think this is true, but I don't know if a long term study has been done. I've seen 5.4 owners claim to get anywhere from 9 to 19 MPG. I've made it to 18 myself, with a long, straight flat road and a 40 MPH tail wind, but that was not typical.
As for the V-10s, I've seen figures from 7 to 18 MPG.
Instead of purchasing based on MPG, you should look at what you want to do with this truck and select your drivetrain accordingly.

I get an average of 13.5 MPG. "99 F250 Superduty, 5.4, 4x4 reg. cab, 4.10 gears. As others have stated, you need to keep the truck well tuned, and be easy with the throttle to get the best MPG. These trucks are made to WORK!

hhmmm... I get about 15-16 in town and 17-19 highway (better if I keep the speed at 70 or less) out of my 7.3. They can be found reasonable if you don't mind slightly higher miles. I got mine with 60k on the clock for ~21k back in January. Others have gotten 7.3s for between 10 & 15k with over 100k on them, but that's not a lot for the 7.3s by any means. I guess it depends what you mean by "can't afford a diesel". I can't afford a new diesel either!!

I guess if you want a diesel and good MPG save up and get one, its what I did. I used to have a little ricer, but it was pretty much useless in winter and I couldn't haul anything. If you want a gas motor I would go with a V10, over the 5.4L, even the MPG is a little less when empty. But depending on what your hauling maybe you don't need a superduty.
