Asked by firewalker_john Feb 20, 2008 at 05:10 PM about the 2008 Ford F-250 Super Duty XLT Crew Cab LB 4WD

Question type: Maintenance & Repair

I have a 2008 6.4L Diesel and I’m having problems with the mileage being much less than my 2005 6.0L mileage. Im also having a lot of problem with warning lights coming on that the FORD tech line will NOT let the dealership fix since there is no fix available at this time. I am getting ready to fill Limo Law procedures. When they are completed im thinking of possibly of getting the very same F250 but in the 6.8L V10.  I am wanting to find out how other drivers are liking their 2008 V10's before I start my procedures.

One of the "tows" in our fleet has this engine, well I would NOT recommend it if gas is a issue with you, the one on our fleet barely gets 6-7MPG on a good day. A friend had one in his "personal" truck and can get 9MPG if he is good to it. The truck has LOTS of power, but when you need to "GO", you can watch the fuel gauge move. We have had a few "lights" come on, but we found out it was just a few "bad assembly" items (one was a vac hose the other was a bad wire). The diesel would be my choice, but for some reason our 6.6 Duramax (Chevrolet) get almost Twice the mileage that our Ford diesel (and the chev is bigger, heavier, and the diesel is bigger). You might find that the gas is a lot more work and expense than the diesel. But if you are having troubles/or you have given up on the truck, you might want to check out other "diesels". Best of luck, hope this helps.

I drive a 2001 F-250 SD XLT with a 6.8L V-10, it has around 143K miles on it and gets around 13 MPG on the highway and about 9 MPG city on a good day. I LOVE my truck, but the gas mileage is a killer, especially in and around the city, but it can take a beating that's for sure! Like a 60mph 360 degree spin across 4 lanes of traffic with a guardrail collision kind of beating.

The V10 might get better mileage unloaded, but once you start towing its going to be just as bad as the 6.4, and less fun. Call up Spartan and order their tune with the DPF delete. You'll be over 500rwhp and probably improve fuel mileage by AT LEAST 3mpg.

The Chevies are far lighter than any of the Ford 3/4 and 1 ton trucks. Ford super duties are the heaviest of the big three. The curb weight on my 06 extended cab is 7600. Crew cab chevies are lighter than that even.

I agree with Mike, call up Spartan and see what they can do for you. My dad's friend was having horrible fuel mileage but got the DPF delete and DashDAQ. They went on a trip to Dallas I believe and got 19-21 mpg on the highway. All with about 450-500 hp to the wheels too.

The 6.4 Power Stroke has a much longer break in period than tour previously owned 6.0 had. If you get up to about 50-75k miles on it you should see a substantial increase in fuel economy. As for the 6.8 it will get decent mileage until it is put under any kind of a tow then expect low teens.

I've heard the same thing about the 6.4 Power Stroke. I have the 6.8 in my 2008 F250 and from my experience "low teens" is a pipe dream, ESPECIALLY while towing. If I "baby" it I get 9-10 mpg mixed driving. On the highway if I maintain a reasonable speed I can get up to 12. While pulling my 6000lb camper my mileage drops to 7-8 mpg. Ouch. My brother gets 14-18 mpg with his Cummins Turbo Deisel, and it's not even fully broken in yet. Even with the higher cost of that engine, and the higher cost of deisel fuel I think he's way ahead of the game. *Sigh* Sometimes I wish I liked Dodge over Ford...

I have a 2001 F250 2WD w/ the V10. Best mileage to date was a flat interstate run with teh cruise locked in @ 65 MPH, pulled 15MPG with no load/empty. I now also have a 2002 F250 (just bought today) with the same engine and 123K+ on it. It has the Lariat package and therefore has the display showing the acquired overall MPG of the truck since new (early one, before they came out with the ability to reset the display around 2004/2005, had a 2005 version of this truck too at one time with 6.0-junk!) That said, the mileage displayed on the meter is the overall average for the entire 123K life, which is 11MPG. Take into consideration this was a work truck and towed a 7'x 14' box trailer almost it's entire life and that's not too bad in my opinion. I haven't had the truck long enough to check out what I can do with it but that's first on my agenda for it!

My Dad has a 2006 F-350. Is the warning light saying there is a TBC (Trailer Brake Control) fault. That was the problem with ours. Our local dealership said it was a module. of some sort that pertained to the towing package. I also know that the V10's were poor on mpgs because they were just a bad engine. thats my opinion. You don't have take this advice. Im only 14 so im not the smartest person in the world, but I know a little here and there. I think that drivers with 250's and V10's are not happy. i know one who wants to trade his in because it gets like ten mpg. So hopefully this helps.

I love my V10. I have owned two and have not had any issues however, the gas mileage is not the best. I average around 12 mpg mixed driving. The best I ever got was unloaded straight highway driving and I was able to get 14.5. These are hand calculated not going off of the lie-o-meter on the dash. Towing my 8000lbs campper I generally see around 8.5mpg. They are great trucks and maintenance is cheap compared to the diesels but you defenitely pay at the pump.

I have gotten another v10, this time it's a 99 F-250 Ext Cab Auto 4x4 Long Box. It is getting 14.5-15 mpg highway and about 10 mpg city. I love the V10 and will never get a V8 in the big truck again, it's great fun. And beside who buys a big truck for fuel economy? It only cost's me on average 100-120 dollars to fill up (Depending on the price of gas).

I have a 2009 F250 super duty crew cab 4x4 and was getting 12-14 mpg average driving and had a tune up done then lost all of my power. I don't know what happened and was trying to look for help from you all. It is a v10 6.8 anything you can do would be appreciated. I have about 64,000 miles on it and it seemed like when I got it back there was no power for towing. Thanks for the help

If your not geting a rough idle or any misses when running it i dont think I would link the loss of power to the tune up. Unless of course someone put some cheap plugs in it. There was a TSB for the catalytic converters/ Y-pipe on the v10. If you had one fail you would feel a serious loss in power. Easy way to check it crawl under the truck and tap on them. I you hear a rattle in the cats thats where the problem lies.
