I am interested in 2011, 250-350
Gas and diesel fuel economy
Wanted real world numbers towing,city,highway 55mph 80mph
You get the idea
Also likes and dislikes on the new truck
I just test drove a gas and diesel but could not drive far enough to get an good average.
Any info would be good

 

because you don't have enough posts (25), you can't use the FTE search function, but you can use google and look only on FTE..

there are a number threads in the 2011 6.7L Ford Diesel - Ford Truck Enthusiasts Forums section on diesel mileage..

Sorry more interested in numbers on the 6.2 the diesel

 

The diesel is a 6.7L

 

he meant 'than the diesel'..

F350 4X4 XLT crew cab, 6.2L gas, 3.73 gears. Daily driver, occasional towing.

I'm getting 15-16 mpg average cruising empty at 70 mph highway (about 1800 rpms.) Around town, depending on the right foot, about 12-14 mpg.

If I back the speed down to 60-65, I often approach 17 mpg, again highway and empty.

I don't have any good figures for towing loaded, really haven't kept track.

4500 miles on the truck so far and running great.

 

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 ), 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? I have attached a photo of my machine below.

 

That is one NICE pickup

 

26 to 27 MPH average speed???

You need to find the pedal on the right hand side of the footwell...

 

Hummmm... yes, well the machine has been over that speed, as stated that is the "average" speed. To calculate; take a tank of fuel, add up the miles to run thru that tank of fuel, then take the time off the clock to run those miles and do the math, you get the "average" speed. Remember, all the time spent at red lights and in traffic does take it's toll on "average" speed. If you do that calculation I am sure you will be surprised at the number you come up with for your "average" speed per tank of fuel.

 

My BMW R1200RT motorcycle shows on the travel computer an average speed of 47 mph. I don't do much city riding on it, out here on Az I mostly run it at 70-80 mph out on the big roads. but just stop at a red light for 2 minutes and it knocks down the average a bunch.

 

Actually I've done this with my 6.0 for over 80,000 miles and it is right at 43 MPH...
Your MPG's will improve as your average speed increases...

 

I have 2400 miles on my 6.2 and it is pretty close to the same miles per tank as my 03 6.0L was. It averages in the low teens, but I am grossing 23,000 lbs 2-3 times a tank. On the hiway empty It will show 15 average on the dash.

 

Thank you Yes
