Smile 2011 fuel economy gas and diesel

Ok guys. How about some real world reports on fuel economy.


I am hearing that ALL manufacturers diesel engines are producing lousy fuel economy. (ie. neighbors Duracrap is providing him with 10-12 mpg empty or loaded).

I don't care that Ford states an 18% increase in fuel economy. What I care about is real world, observed fuel economy.

So guys, What kind of numbers are your 6.7 PowerStrokes providing?


How about the new 6.2 gasser? What are you guys with the 6.2 gas seeing as far as fuel economy goes? 18mpg? 8mpg?

From what I have read, the 6.2 is seeing mid to upper teens and the 6.7 is seeing high teens to low twentys.

Test drove a 6.2L today and the computer said ~18 when the speed was in the low 60s. This was about 7,000 feet above sea level so there was little oxygen but little wind resistance either.

I remember back in 04 and I was looking at new trucks.I already had owned 3 F250's and new honest mpg's.I was letting the salesman think I was ready to buy and asked him about milage.He said alot of reports were in the 18 mpg range.I said WOW that is great.Then I hit him with where do I sign and by the way if I do not get 18 mpg I want a clause put on my sales slip that I can return it if I do not get that kind of mileage.He then said well I have heard that kind of economy but cannot verify it. Funny how stories can change when they are called on it.

Just a heads up on the dash meters - they can be off. Hand calculate your mileage to really know what it is. I've seen 17.5 out of my 6.4L, hand calculated, with the meter showing in the 16's. I've also seen the meter read higher and my hand calculated less. You never know what that meter is going to tell you.

I tend to get a little less than these guys w/ 6.2 - Straight highway running 75 - about 14 - when in town or ranch roads it pulls down 10.5 - 12.. Towing heavy - 8-9

I knew that using the reset button to make a device designed for long term averages to obtain short term averages was questionable. Not many choices on a test drive. As long as we don't know how the measurements are made and averaged the possibility of a poor single measurement (outlier) messing up the results exists.

The meter was plausible if not correct. On a downhill I saw it hit 27. Not significant but it is suggestive that the sampling isn't infrequent. BTW computing the MPG by hand has a sampling rate on the order of 1 per e.g. 300 miles!

Don't forget to read the whole story then if it's the 6.7. If someone is getting high teens to low 20's then their driving on highway running 55 to 65 mph MAX! I've been on several road trips over 500 miles each way and that's the only way I got close to 19.5 mpg.

The last trip was only 200 miles and I babied it at 65 mph for the first 100 miles, and only got 18.4 mpg.

I run that trip several times a year. I run at 75 always did always will as long as the conditions will allow. I also have a retrax bed cover. I got 20.8. Please don't tell me what speed I drive at. Your mileage may be affected by being a 1 ton and cutting your front valance down in size allowing more air under your truck. I am likely a better driver than you as well.

My 6.7 gets around 16 in town, unloaded. With an enclosed trailer in tow running long interstate runs I get between 11 and 13. I run whatever the speed limit is, plus 2 to 5 mph.
