40 Gallons? Do you have a special tank in there or aftermarket one? Factory tank is 35 gallons from all data I can see. 37.5 for some.

From the Lie-0-meter i drove from Baltimore, Md to Berkley Spring, WV. about 140miles and a few mountains, i got a average of 14.7mpg. Not towing just a 4-wheeler in the bed. 3:73 gears, did find when on some side roads heading up the mountains had to lock out 5th and 6th gear to stop the tranny from shifting, maintaining 190 degrees on the tranny.

14K miles on my 6.2, 3:73 gears. 14.8 is the average I have been getting for a while. no towing, 70% highway miles at 75mph. 30% around town. I guess that will be it.

That mileage is not bad IMO. I'm getting about the same. The best I've got is 16 mpg 100% highway driving. It's still much better than my old stock 6.4 and my old V10. I'm happy.

6.2L gassers.. how has your MPG changed now?

It has been almost a year since this thread was started about the Ford 6.2L gasser.
I was just wondering has any of you noticed any changes now that yo have added a few more miles?

What kind of mileage you getting now with broke-in engine?
I have attached a picture of an F-250 that looks like the one being built for me. Supercab, Lariat, 3.73, 8ft bed, 5th wheel prep, sprayed bedliner, Color is Royal Red and Adobe.


Thanks

I am up to 27K miles on mine now and there has been no change at all from the first month I drove it. The milage will run between 14-15MPG average, not towing, 60% Highway and 40% town. If you run around 50MPH for extended times it will go up to about 17MPG max and when strictly around town around 13.5MPG. I reset my Trip B meter and have let it run for the last 8000 miles and it shows 14.7 MPG average.
I have no complaints other than the transmission is a bit quirky at times even after I have had the TSB to correct rough shifting, that made a huge improvement, but it still acts up every once in a while with a shift that feels a little rough. Nothing to bad though and I dont let it freak me out like it used too. I enjoy driving it and still get compliments daily.

NJ to LA 1,350 miles? Did you take a short cut I don't know about.
Anyway that is great MPG mileage. I hope mine get at least that .


Anyone have any secrets on Break-in?
I know you shouldn't pull heavy loads until after 1,000 miles.
Start driving different speeds and not long runs at the same speed.
I also heard some change oil at 1,000 miles then every 5,000 miles.

What do you think?

When I first got mine I wanted to change the oil before 7500 miles and I called two Ford dealers and they both said its a waste of money. They said wait and change it every 7500 miles as Ford recommends as they know more than I about the new 6.2.
I have had no problems and its nice saving the money so I am sticking with the Ford recommended service intervals.

I have a 2011 f 250 with the about 6100 miles on it. When I first got it we got 11mpg after about 3000 miles it started getting better and in country driving we get 13.5. x-way is around 15. Towing our 16000 pound 5th wheel we get 7.5 which really sucks

1st Trip pulling 5th wheel

Overview
Just got back from a 700 mile trip pulling a 5th wheel trailer and wanted to update you on the performance and mpg on my new 2011 F-250 6.2L. Truck had just went over 1,000 miles before trip. Trailer 10,000 lbs

Truck - 2011 F-250, 6.2L, LB, SC 2x4, 3.73 rear

Details
This trip was mostly on Interstate highways and I ranged speed from 55 mph to 70 mph.
I kept transmission in D and did not manually select or remove any gears.
The trip was from Phoenix Arizona to San Diego California and back.
Most of the trip was level except for the climb at Palm Springs westbound.
Westbound I had a headwind of 8-10 mph which hurt mileage.
In Arizona I drove 65 -70mph and in California 55-61 mph.
AC was always on for the entire trip.
My 30ft 5th wheel weighs 10,000.
Most of the trip I stayed at 61mph and 1600 rpms which was the sweet spot for the Engine & Trans.
All of my fuel was 87 octane with 10% ethanol which I didnít like but that what was available.
Outside air temp ranged from 65 to 90 degrees.
When filling with fuel I pumped until the automatic nozzle clicked off and I went up to the next full dollar amount. This makes all fill-ups consistently close in being the same.

My observations.
Transmission took at least 5 miles to get up to 165-175 degrees.
Transmission temperature ranged between 184 Ė 199 degrees.
Engine had plenty of power and torque in all speed ranges.
Transmission did not miss any gears and was very smooth shifting.
The exhaust sound is good at cruising and downshifting sounds great!
Pass a few trucks pulling trailers, Dodge Cummins, Ford F-150 and even an F-250 Powerstroke.
Engine response was very quick when I needed it.
Mileage westbound with headwind was 8.7 mpg. (Hand calculated)
Mileage eastbound was 9.3 and 9.4 mpg on two fillips. (Hand calculated)
When hitting the headwind the truck liked 5th gear but quickly changed to 6th when wind decresed.

My thoughts and conclusion
I converted from a F-250 6.0L Powerstroke diesel to the 6.2L gasser.
Iím very happy and have been pleasantly surprised in the performance of the engine and transmission.
I hope with time and miles my pulling mpg may raise and reach 10mpg which I think is possible.
The continental tires were good and quiet on the highways.
Hopefully this will give you a better idea of the performance of the 6.2L gas engine.
In the next month I will drive 3,000 miles pulling this trailer. I will update you after the trip.
