Real world mpg on Ford F250 Gasser

We're having a change of heart - we were looking at going with a diesel, but the upfront cost is gagging us. Anyone out there driving a later model F250 and can give us gas mpg both towing and not? Our AS is a 25 footer and we don't exceed 60 mph when pulling her. Thanks in advance.

The rule of thumb is to deduct 30% from the highway figure. This works whether a 1965 or 2015 gasser. Can be forty, but not quite likely.

Sorry I cannot comment on the F250. Other than to say the extra 8-10 grand is only the beginning as the fuel is about 30% more than standard gas. I can confirm we (averaged) 13.5 mpg with our f150 eco-boost on a trip of about 10,000 miles. This mileage was a combination of mountain and prairie driving pulling our 28'.

Rollster, sent you a private message on a used F250 Diesel, it was my truck and is at a dealer now. I sent you the link - NEVER a bit of trouble with her and I think it only has about 12,000 miles on it.

Good Luck

My Excursion gets 8-9 MPG towing and that is usually running 65-70 MPH. You might get 10 out of it, if you drive like grandpa or someone with a handicap tag. It has a V10 and a 4:30 axel. It was cheap to buy and is cheap to maintain. No more 15 quart oil changes, fuel filters, coolant additives, DEF fluid, expensive fuel, and that is if nothing breaks. Just a minor out of warrantee repair will cost more than I paid for my Excursion. It has the same basic running gear as the 2000 era pickups. The engine and the axle ratio will affect mileage.

Are you looking at newer V8 250s, or older V10 250s, or both?

If you're thinking about the V10, there's a forum member called pappy19 who is a big proponent of those (to put it mildly!) Send him a PM if you want to find out why he likes them so much.

Carol I had a 2014 GMC Sierra 5.3l gas and switched to a 2015 Sierra 2500 Diesel. Fuel has been about 25% more expensive but my mileage while towing has run 26-28% better and around town has been about 5% less. I keep good records. So the fuel delta is minimal. Only reason for me doing the diesel was I live in Colorado and lots of mountain driving. Just simply pulls better and the diesel brake on the downhills really helps control the speed.

If you are flat lander primarily the gas would be fine. Diesel purchase is higher, you have the cost of DEF (exhaust) fluid at about $24/5,000 miles. Oil changes will be more because of more oil and filter cost is higher.

Hi from AZ. . . My '08 F250 4 door FX4 with the V10 got about 10 mpg. Didn't mind that when pulling my Safari 25 across country, but ALSO got that taking me solo to the land of orange aprons (aka HD) Talked to lots of people about improved mileage ideas & they all said 'yeah 10 mpg, that's what they get' Great towing truck though, if I could have afforded a separate daily driver, I'd have kept it. ........regards, Craig

I have a 2008 F-250 with the V-10 (6.8) and have 150,000 miles on it. I average about 11 mpg solo and towing our AS, I average 8.5 mpg. Never a moments trouble, $19.95 oil changes and $10 fuel filters. I Seafoam the tank every 10k for another $15 to keep the injectors clean.

The newer Ford V-8 (6.2) has been a trouble free engine as well. The newer trucks all have the Ford Torqueshift transmission that has been bullet proof for many years. Ford took the best qualities of the Allison and improved the internal parts to make their new tranny. A good used V-10 from 2005+ is hard to find. Also finding a well equipped new V-8 is equally difficult. I ordered mine from the Ford factory equipped the way I wanted it built. You might also look at a lease instead of a purchase as you will save a lot of money that way. At the end of the lease you can buy the truck or give it back to Ford.

Two cents on an f150 pulling a 25'.

@65---12 mpg avg two years
@70---11 mpg avg (I creeped up to traffic speed with MS2 truck tires on occasional stretches now)

Reg v8 4.6 3V for comparison

Here is something else to keep in mind. In Toledo, Ohio at a circle K yesterday regular gas was $2.74 and diesel was $3.93, and that's just the cost of fuel. We average 10.5 towing with a F250 6.8 V10 with a 4:10 rear end gear. Our trailer weights in at 6020 lbs.

Diesel is only 95 cents a gal higher here.

F 250 gas mileage

I know you asked about Fords. However, you might look at the Ram 6.4 gas engine. So far very favorable owner reviews. It gets about 10 towing and maybe a lucky 15 or so solo. As a comparison my Ram Cummins gets 20 solo at a steady 65 mph hand calculated and 13 towing 8000 pounds. And where we live diesel is not that much more than gas. The Cummins is a real workhorse if you are thinking diesel. The 6.4 gas has cylinder deactivation to save on fuel when the engine is not working hard. The 6.4 is worth a look!!!

My '11 F-250 with the 6.2L gas engine has slurped 9 to 11 mpg towing a sailboat where boat and trailer and stuff (including anchors, chains, one cat ,,,) weighs ~8,000 pounds and I drive ~55 mph. The boat probably has a lot less wind resistance than a travel trailer. The truck is an extended cab short bed and weighs (I guess) ~6,500 dry, and measured 7,000 with my wife, myself, and 35 gallons of gas. The truck is white (high in titanium dioxide) and that of course helps.

Around town, not towing, I can average >14 mpg since I have few hills and get into and out of town by interstate at, again, 55 mph. Accelerating or climbing with 7,000 pounds is costly. Traveling cross country (not towing) I've never had a tankful at 19 mpg but 17 isn't hard (at 60 mph) and 18 is doable.
