The engine is actually growing on me each day. In the beginning I was really babying the thing with slow acceleration and such. Now that I have 2K plus miles I am starting to push it a lot harder. Still no towing, but I do mash the gas pretty hard and it has some good power. When driving over 25mph if you step on it, it has good pickup speed in and out of traffic. From a dead stop it's about what you would expect from a Super Duty, but like I said once you get in 2nd or 3rd gear, you can really feel the power when accelerating. Hope this helps.

OK Dudes, here's the 411 on what I have seen so far on my machine. First, I took delivery of my 2011 F-250 SD on 18 June. It is in Lariat Super Cab FX4 trim, 6.2 gasser, 4.30 gears in the rear end. This is my 5th "truck", first Super Duty. All numbers are from actual miles driven and fuel uploaded. I always fill, refilling after passing the 1/4 point on the fuel gauge with 87 octane Shell gasoline. I have refueled the machine 4 times so far. I use the machine mostly local, have towed a 3,600 pound boat twice, (175 total towing miles http://www.blueovalforums.com/forums...ault/shift.gif ), towing only after the first 1,000 miles. When I ordered the truck I went with the 4.30's instead of the 3.73's because by my calculations, on the type of driving I would be using the machine for that the fuel mileage would not be that much different than with the 3.73's and the towing would be better. I do not drive for hours on limited access highways at a steady cruise speed. In that case the 3.73's would show there merit.

The average speed calculation comes from the engine run clock and the miles driven between fueling. I do not let the engine idle anymore than necessary and get underway within 30 -60 seconds from start up. I drive in a consistent manner and do not zoom away from stop lights, as I see my share of them. Besides, only a fool would drive like a cowboy in a 6,500+ curb weight machine.The average speed is an interesting number because it shows just how slow actual point to point driving in a non-limited access road environment is.

So far I am very impressed with the new 6.2 engine, it's very smooth and powerful. I don't think that the guys with the 3.73 final drive are doing much better with their average fuel mileage.

To Date: 1,632.9 miles on the clock

1st tank of fuel:
engine clock: 12:54:00
miles: 354.4
average speed: 27.47 m.p.h.
fuel milage: 12.51 m.p.g.

2nd tank of fuel:
engine clock: 13:08:50
miles: 348.2
average speed: 26.48 m.p.h.
fuel milage: 12.23 m.p.g.

3rd tank of fuel:
engine clock: 10:19:10
miles: 282.3
average speed: 27.35 m.p.h.
fuel milage: 12.16 m.p.g.

4th tank of fuel:
engine clock: 10:18:50
miles: 284.7
average speed: 27.59 m.p.h.
fuel milage: 12.39 m.p.g.

The numbers are derived from a spreadsheet I keep, my the trip computer looks pretty accurate, calling out 12.2 -12.5 miles per gallon. What final drive do you guys have in your machines? http://www.blueovalforums.com/forums...ult/shades.gif I have attached a photo of my machine below.

Good Info. I've got the 3:73 gears and have 5500 miles. I have done no towing and a lot of interstate driving. I have been getting about 2-3 mpg better than the mileage you have posted.
Still love everything about my truck!

Pops90GT 08-03-2010 08:37 AM

Your truck is sharp looking, is it sterling gray. I am waiting for my 250 Lariat again, the first one the dealer ordered came in with the wrong color and seats. Thanks

Fuel milage update, real world use, 6.2 gasser.

When I ordered the truck I went with the 4.30's instead of the 3.73's because by my calculations, on the type of driving I would be using the machine for that the fuel mileage would not be that much different than with the 3.73's and the towing would be better.

So far I am very impressed with the new 6.2 engine, it's very smooth and powerful.

To Date: 2,965.7 miles on the clock

6th tank of fuel:
(Best mileage on a tank so far, finally had some open road use.)
engine clock: 09:30:00
miles: 348.2
average speed: 36.65 m.p.h.
fuel milage: 14.1 m.p.g.

7th tank of fuel:
(Towed my boat for 175 miles of this tank, or 55.22%)
engine clock: 12:18:52
miles: 316.9
average speed: 36.65 m.p.h.
fuel milage: 12.46 m.p.g.

8th tank of fuel:
engine clock: 12:15:10
miles: 372.2
average speed: 30.38 m.p.h.
fuel milage: 13.23 m.p.g.

I am really glad I ordered the 4.30's, I don't see the 3.73 guys doing any better in fuel mileage and this thing has great low end grunt. If I spent all my time on the interstate the 3.73's would look better. But I can't say enough about how great this thing is.

I just turned 1000 miles recently. I've noticed mileage increase as the break in continues. I do a lot of city driving with a little hwy driving. My last tank was 13.2 mpg & the tank before that was 14 mpg. I've done some towing this morning for about 60 miles and I'll post a good write up on that soon.

385HP 09-11-2010 04:39 AM

Before I purchaced my 2011 Super Duty I never expected good gas mileage, I bought my truck for a purpose, not for great gas mileage.
Look at the mini pickups like the Ford Ranger, Dodge Dakota, they don't get much better gas mileage than the full size pickups, but they can't haul or tow the loads like the full size trucks.
Be satisfied that you own a Super Duty knowing you can do more with it than owning a mini pickup, also your 2011 Super Duty, gas is flex fuel, you can get E85 for 10 cents less per gallon.
You can make money with your Super Duty, plowing snow, hauling, towing a 5th wheel trailer (5th wheel trailers are getting more and more popular where some trucking firms will hire you to haul large volume, lighter loads, If I owned a 5th wheel trailer I can get a hauling job tommorrow hauling windows and insulation) " 85 cents per mile "
thinking about owning a 5th wheel trailer, but I have a full time job with lots of OT, if I didn't have a full time job I would own one.

All good points, yes this machine is NOT a Toyota Prius (Thank God!) and fuel mileage is not why you buy one. But I do think that for this machine to get 12 -14 mpg's under normal use is a plus for the 6.2 gasser. Machines like this use to get 8 -10 mpg's, with less power. I'm just saying. :banger:

I agree....mine gets just shy of the mileage I got with by 2006 6.0 that i just traded.

MonteCarlo31 09-16-2010 08:35 PM

Very interesting reviews here...I've been lurking and am having a tough time not going with the 6.2. I've been truely soured by the past Ford diesel and even more so when I built a spread sheet that broke down mileage costs. The new diesels just have too much to go wrong to make me want to try them. I'm thinking I might just go with a 6.2L F-350 this time around.

I've got a 66 mile a day commute (33 or so each way) and of that 28 miles of it is highway. I'm wondering if, with 4.30 gears I could pull down 14/15 mpg.

It seems very possible since my commute is pretty flat with about a 20' change in altitude the entire trip and usually stays at 70 mph and under.

Any thoughts? I'm currently getting 14.5 to 15 mpg w/ the a/c on in my Z71 CC/SB w/ 285 BFG ATs and 3.42 (yeah yeah they are TOO tall) gears.

As stated, I have only had my machine for a shade over 3,000 miles. (I have the 4.30 rear set) I have seen 14.1 on a tank, and I would not really call it "highway" driving on that tank full. I am sure you will see 14+, 15? maybe. I am happy with the 4.30's

I think you can pull 14 to 15 mpgs out of a tank with 4.30's since most of your miles will be hwy miles. With that much highway driving you will possibly be able to pull 15 -16 mpgs with 3.73's. I'm going out of town this weekend and most of my miles will be hwy miles. I'll report on my mileage from that trip to give you more feedback to work off of. :thumbsup:

Thanks, I'm very interested to see what you'll get on the highway. 90% of my driving is the highway, 3% is probably back roads and 7% is off road / 4 wheel drive.

I'm guessing that with a nice bed cover (to keep equipment safe and dry) I should get 14-15 when I switch to the BF Goodrich ATs.
