    Im lookin at f-250s. They say the V10 will get @ 15 mpg. The 5.4lt V8 @ 17 mpg any truth to that? Im leaning toward the 5.4 but the best deal I've found is on a V10. Im looking at 2000 thru 2003 year models, anyone have any experience with these models good or bad?

    Towing, that V10 will get better mileage. Take that for what it's worth.

    I would guess that if you drive a lot and tow a lot the extra money that you would have to pay per month for a diesel would be less then the extra that you are going to spend in fuel. Just my 2 cents.

    I have a 2003 F-250 XL model (basic work truck), with the 5.4. I have a cap on the back, with a shelf for more space. I pull a 6.5X12 Big-Tex, single axle, with a w/b and two hand mowers, plus a few other items (all power equipment is on the shelf under the cap, secure and dry). I work solo, with about 40 customers, doing primarily mowing. All travel is local neighborhoods. I bought in Aug 2003, and now have about 9,400 miles -- so not many miles, just stop/go and short hauls. Rarely am I driving over 40 mph.

    I get about 9 mpg, and I drive very easy.

    I'm disappointed in the milage. It is much less than my old F-150, 4.2L in-line six, with manual transmission -- making the same haul, same routes, etc. It managed about 15 mpg.

    I get 12.5mpg average running empty with my F350 4x4 w/V10 and 3.73's. Have gotten as high as 16mpg, but that was open highway @ 65-70mph. Towing a 5000# to 7000# enclosed trailer, no worse than 10mpg.

    I had a 2 wheel drive 04 F250 with the 5.4 and 3.73's, got 16 empty but towing it dropped to 10-12. Now I have a 4 wheel drive 05 F-350 with 4.10's and I get 12 empty and 10 towing. I love the V-10 ,it has so much more power than the 5.4 and towing it does as good on gas as the 5.4. I would not go back to the 5.4 now that I have the V-10. So if you are going to be towing a lot, get the V-10, if it is just going to be for transportation then maybe the 5.4 would be better ,but again you will love the power of the 10.

    I can't believe that V10 would get good mileage, our F250 with 460 get 7mpg towing our lawn trailer around the city. We switched to our van with 350 and it get about 9mpg. Usually you can't get mileage info on the F250 so where are the numbers coming from? We are buying F150 in the future then we know what the mileage will be, or at least close to it.

    Hey ya'll thanks for the input. I think i've decided on an 8cyl. I dont tow heavy loads that often. I have a 150 gal spray rig in my f-150 4x4 now. That weighs @ 1600 lbs full, an f-250 5.4 should get the job done. I sometimes pull a bobcat for snow removal but it doesn't snow often enough to worry about. Now if I can just find a deal on an f-250 I'll in business.

    V10, you should be able to pick one up for nearly nothing.
    Single didget fuel mileage, Period...

    Sooner - Before you buy that F250, check the real payload numbers. If the GVW is 8800 and the empty truck weighs almost 7000, you're going to be overweight with that tank and a couple of people on board. The truck will handle it, but don't get stopped or have an accident.
    I wanted a V10 when I bought my F350 in 2000, but all those motors were going into Excursions. Mine is a 4x4 supercab longbed 5.4 with 4.10 gears and a stick shift. It has plenty of power without a trailer, and carries 3500 lbs. (or more). Biggest loads I've towed were a Bobcat 331 excavator and an overloaded dump trailer scaled at 14,000 lbs. Went down the road fine, never overheated. Also many thousands of miles pulling an 18-foot 7700-lb. box down the highway. No problems.
    Mileage ranges from 9-10 towing at 70 up and down hills to 16 running empty. Usually 11-13 mpg because I've got a heavy foot. I've heard the V10 is about 1 mpg less across the board, but with more power.
    Diesels are great until you have to fix 'em. In 85,000 hard miles I've spent $200 on a new serp belt. My buddy has a diesel, he runs all local short trips, and I know he has over 10 grand in repairs in 65,000 miles. Nothing major, just injectors and pumps and glow plugs and starters, etc.
    Good luck with your purchase. You'll be fine if you do your homework. GB
