First time since I bought it......a nice little highway run of about 100 miles.

With 600 miles on the odometer I averaged 22 mpg at 65mph by the fuel screen.

My '09, with all the same rear end, 4x4 etc... Never got above 19mpg on it's meter.

The 5.0 is a big improvement in performance as well. I am very happy.

 

Very cool!

 

Not bad at all man... very nice

 

Nice!

 

Thanks for the update, Brian. That's a 15.7% increase over your best mileage on the 09 and 22% over the 18mpg the 09 was rated for. If that increase carries over to EB we could see 23 to 26 on EB 4x4. There is no way I would buy a 2010 with one of the old engines right now.

 

and are you only going by the lie-o-meter or are you doing physical hand calculations?? these are usually 2 diferent numbers unfortunately.

 

Took my screw 4x4 5.0 w/3:55 on first road trip last week. It was 300 mi. round trip & had about 900 mi. on her. Running w/cruise set @ 72 mph averaged 18.7. If you drop down to 67 mph it goes up 2 mpg. I figured mileage by hand although truck computer seems to be right on the money now.

 

and this is in TX so no winter fuel.... Just remember for guys up norht where we lose 2-3mpg Nov-March..

 

Really? The mpg reading in my Mustang is very accurate at the end of every tank whenever I fill up, usually within .1 of my hand calculations. I get 21+ mpg in my GT consistently. The one in my wifes Acura is also almost dead on as well.

 

X2 on that.

 

When I checked mine it was off .2 mpg. In fact hand calulated showed I got .2 better than truck computer.First tank I got 18.0 hand calc. with mixed driving. I am on my second tank now and truck is showing for a week of driving 17.2 with all city/metro driving.Thats a lot of starts and stops.I think the truck computer is fairly accurate.It was on my 09 also.Sometimes a little more and sometimes a little less but it averaged out close.Unless you fill up at the same location and same pump and same temperatures everytime checking by hand can be off some also.If you fill up at the end of a warm day the remainig fuel in the tank is expanded and it will not take as much to fill it up giving good MPGs.Fill up on a cold morning and remaing gas in tank is shrunkin so it will take more to fill it up giving poor MPGs.Most gasoline storage tanks are buried underground not seeing these temp changes so that volume will not change much.You need to check mileage several times in a row to get a good average doing hand calculations.A one time pick out of 10 is not a very accurate average.

 

I have checked computer vs hand several times.Extremely close to right on every time. I'll go by computer from now on. I can say for sure my mileage & performance has improved vs '09 5.4.

 

Maybe they fixed the computer readings on the 2011. The 09-10 trucks are never right. Usually a 2-5mpg difference from what I have read. I see about 2-3 mpg difference on mine. The Miles to empty is way off too.

 

yes it gets great mpg from the comp fuel meter havent filled mine up yet but im very pleased so far 190 on my odometer

 

FORDMOCO just ran a commercial on FOX's NFC Wildcard game that stated the new ECOboost engine is rated at 22MPG's HWY.
