I just checked fords site. You can still get the heavy duty payload package is what they call it.

Depending on what you get the truck configured as it has a payload rating between low 2000 and low 3000 lbs. You can get it with the 5.0 v8 or 3.5 ecoboost engines.

Very high probability you have to order a truck to get it.

Bump. Thinking about ordering a 7.3 gasser, anyone have any MPG #’s to update this thread with.


Or real world experiences, good or bad.

From Fuely, a website many use to calculate and track fuel mileage.

The overall average is just under 11 mpg. There appear to be two peaks in the data I would assume its due to either the different rear ends available or those who mainly just drive them and those who tow with them.

I was at that sight before I posted my question earlier. When I put the 7.3 into the filter, only 3 bars pop up, so some of those are probably diesel numbers. So fricking torn on this and can’t find enough real world mileage to make up my mind. There has got to be a more consistent source somewhere.


When filtered the 7.3 is averaging about 10-11mpg, the 6.7 is 14-15mpg, I wish they numbers were broken down into towing and non-towing. The diesel is $8k upgrade cost over the 7.3, but you also get a longer warranty on the diesel. Higher maintenance cost though.

Grout, there’s some YouTube guys posting MPG’s on their 7.3 gassers, but I’d sure like to talk to someone that owns one also. I’m thinking the 10-12 is pretty close, might be a little better.

I thought the 12-14 mpg was bad on my 6.2l.

My B.I.L. has a 2021 F-250 CC long bed 4x4, platinum he loves it say it's got gobs of power, and passes everything but a gas station. 10-11 mpg unloaded!

Grrr, I’ve been reading everything from 9-15mpg. I’d be happy with anything over 13mpg, but I’d be pizzed at anything under 12.

Not sure what ratio his axle is, I would guess 3.73 but could be 4.11??

From what I recall of your Ford diesel you dont get any better than low teens in it, I wouldnt expect to get the same mileage in a gas. That said If you are getting 13-14 mpg in your diesel and 10-12 in the gas, I think you would be saving money with the gas.

12 in the diesel I only bought it (diesel) originally because the service advisor said it would get 17+.

There was a thread somewhere that mentioned websites that buy vehicles, any of you guys know one? It might have been over on BBC though.

My '20 model F250 with the 10sp trans get 20-21 on the highway, 15ish around town, and 12-13 towing my bay boat over 70mph. That's 2-3mpg's better then my '13 F250 did.

With my truck luck, I would be the guy that gets 13-14 and cursing the truck.

You even reported low teens mpg out of your 5.9 cummins didn't you?

I don't know what it is about your use that is different than so many others, but I've been around here a long time as have you and I always remember you posting up some pretty low fuel mileage numbers. My dad has a late model cummins, he averages over 20 mpg commuting and 14-15 towing a 5000 pound 24-foot center console. Do you idle a lot? Floorboard it at every stop? Loaded all the time? Do you routinely check your fuel mileage?

A little higher then normal but this was leaving South Padre Island a few weeks ago. Running at sea level on flat ground for close to 100 miles after filling up.
