F250 6.7 tow mpg

poofam · 03-09-2016, 08:57 PM

Well my friends I need your help, I am in charge of getting equipment at work and our crew trucks are currently f250 6.2 gas pulling 10,000 lb v nose trailers. We are looking at the 2016 f250 crew cab 6.7 dully and I would like to get some REAL WORLD DATA on mpg pulling 10,000 lb +- trailer/5er. I know there are people like me who write down every time you get fuel and calculate True MPG, we have a few f450 6.0 (still running if you can believe that!) so I know about the difference between the too. I just need to convince the suits (skirt in my case) with data that 6.7 is the way to go. All I need is f??, trailer weight and mpg (lie-o-meter or true) we run mostly east coast so flat/hilly terrain. Thank you all in advance for your help !

Towing 10k Diesel is the way to go. Sorry can`t help you out mpg thou.

poofam · 03-09-2016, 09:26 PM

That's what I think also

davel1971 · 03-09-2016, 09:32 PM

gas will do it, but diesel will get about 4 MPG better doing it, and will do it at much lower RPM, much less shifting, and an exhaust brake for the down hill.

I don't believe the F250 is available as a dually.

Got one on the lot

An interesting thing about the newer diesels is that it seems that trailer size doesn't make much difference.
I can put my tandem utility trailer with a Kubota tractor at 6000 lbs behind me, or I can more than double that weight with my fifth wheel (which is like pulling a parachute) and I get 11.5-12 mpg with either one.

I doubt you will ever justify the diesel based on fuel mileage, even though the diesel will get almost twice the mpg, unless....you intend to drive them for several hundred thousand miles...even then, with the additional maintenance cost...

Were it based purely on the numbers, I probably would have saved the $8500 and bought the gas engine. But, whether I'm driving solo, or towing 13,000 lbs of trailer, the diesel doesn't seem to labor at all, and the dang thing will still accelerate going uphill while moving 22,000 lbs. I guess I still have a little testosterone left, because that's hard to not enjoy.
But I'm afraid you're going to be hard pressed to justify the diesel for a 10,000 lb load.

you might want to look again. Nobody has ever made a 3/4 ton dually

poofam · 03-09-2016, 09:55 PM

I do stand corrected it is a 350 xlt

Correct, which is why I asked the question about engine and model year. But, there have been a few garage conversions done over the years.

I get between 10.5 -12 mpg towing 36ft 9,000 lb travel trailer

Wind appears to be biggest factor in that range.

I have a 2012 6.7 F350 Crew cab

When not towing average 16 all around and 19-20 highway

It tows effortlessly

poofam · 03-09-2016, 10:06 PM

Someone posted on another forum a co that sells the kits with fenders. 4:23 am will be here soon thanks all, keep posting and good night ��

I think I can help. I own an F450 v10 gas, set up with flat bed and the bed is equipped as a stake body. We remove the sides 99 percent of the time. The truck is rated at 14,500 gross weight rating and 28,200 gross combined. Flat lander in Illinois. Day in day out it runs out empty and returns loaded or vice versa. We tow either a 24 foot flat trailer or a 20 foot enclosed.
Real world MPG 6.8 empty, 5.0 to 5.1 loaded. Mix of interstate, highway and city. Usually does not matter. If I had to do it all over again, diesel, diesel, diesel diesel. Did I mention diesel.
The worst part of the whole thing, 44 gallon gas tank. Yes boys and girls you start looking for fuel at 150 miles or so. We fuel EVERY day sometimes twice. So on top of crappy mileage, I get to pay the driver over an hour a day to pump fuel. In the first two months of owning it we ran the tank dry twice. The driver did not believe the lie o meter. Guess what it was spot on.

If you need help convincing the boss, send me a message. I would be more than happy to give a pep talk on not what to do. The reason this happened is we had a ford F450 6.0 liter. After spending 38k in repairs, injectors, charge air cooler, turbo, injector controller etc, to nurse that POS to 130k miles my business partner threw a fit and demanded we buy a gas truck. I gave in. Next time I will just fire the partner and buy a diesel.

You need to also consider yearly mileage and how long you will keep them. I face the same arguments pro and con as a fleet manager for our county every year. (900 on road units and lots of data)
The maintenance cost is substantially higher and you will need to put about 20,000 miles a year on them just to make it worth the effort. You will also have a substantial hit in maintenance cost around the 6-7 year mark when everything falls out of warranty and all the fuel and emission items start their downward spiral. (read engineered failure)

Nope.
Never a factory 3/4 dually.

I would say we put about 30,000 a year on the current 250s and keep all trucks till the wheels fall off. We have 3 f150s with 400,000 + mi and looking to replace them now. We have 34 vehicles in the fleet mix of trucks and suv's

ferguson65 · 03-10-2016, 06:10 AM

I put about 2000 miles on this year towing our trailer, claimed dry weight is 9500, never scaled it, but I'm sure its probably 12k ish loaded. Mid profile trailer, 12'4". I get anywhere from 10 to 12 depending on terrain and wind. That's hand calculated, lie o meter is usually fairly close though. Some highway and some 2 lane roads, keep the cruise set to 66 on the highway.

What do you get not towing?
