I took my new EcoBoost powered FX4 on a short, 200 mile road trip this past weekend. The route was probably 50% highway with speeds varying from 45 to 65 with the occasional hill. I ended up averaging 18.6 mpg based on the on board computer. I haven't gone through a full tank of gas yet to determine how accurate the computer is, though.

Just thought you guys would like a little more information on "real world" mpg numbers.

Thx for the info. I'd definitely like to see an ongoing Ecoboost Miles Per Gallon thread.

 

Nah, we should keep posting new threads every few days... no point in making on consolidated thread!

 

Yes I do like reading about the real world knowledge. I haven't really heard of anyone getting the 21mpg on here. But I haven't really heard of anyone with an ecoboost after break in period either. Keep us in the loop!

 

FWIW...There is another thread "Ecoboost Owner's Reports" where a lot of people are posting this kind of info -- you might want to check it out if you haven't already.

 

I consistently get 18.5 - 20 give or take a few points city/local
and 20 - 23 highway at 65 - 68mph. Hand calculated, the computer is always pretty close, within .1 to .5 mpg
supercab 4X2 18" wheels, 3.15 rears
Now don't expect the same out of a 4X4 crewcab, with a heavy foot behind the wheel! I will admit with fuel prices the way they are I work for these results! I don't care who beats me to the next light or stop sign, I will beep and wave when they stop for fuel!

 

This exactly matches what I've been getting in my identically-equipped unit. And it definitely "likes" to go around 65.

 

And it sure is a sweet truck to drive. Took mine from Fl to Pa and back, 1100 miles each way. Like traveling in a Lincoln and the worst mileage reading I seen on the dash meter was 18.2 pulling a 15 mile hill in the blue ridge mountains. Overall averaged between 21 and 23 depending on which leg of the trip.

 

First time update on mileage here.

3rd tank of gas so far...700+ miles so far

Town/highway 15.5mpg
Highway 18.0mp runnin 65mph

Also put in effect i'm running hills/mountains compared to the down south guys

Not what i had hoped for but still better than my old truck.

 

Exactly. What I've found the nicest is how utterly quiet the cab is even at highway speed. Even on multi-hour trips, I don't feel anywhere near as fatigued -- partly because I don't need to have the music on the stereo as loud to be heard over the road noise.

Ford definitely has gotten this one right.

 

Nice looking truck! I like the brown. I have 2011 lariat 4x4 4dr screw 6.5 bed ingot silver, I get 15 to 16 city around 20 highway but have gotten 23 on a short mile trip. A lot depends on how you drive it. I am really starting like this engine. It has the power when needed and the fuel economy when needed.

 

Thanks for all the info and updates folks. I'm liking what I'm reading so far.

Anybody got highway MPG numbers for driving 70-75mph?
I saw an article on AutoBlog.com today that they had hypermiled an Ecoboost and gotten up to 30mpg!

I don't see myself doing these sorts of things nor driving 65-70mph when the highway limit is 70 and most do 80. So to me 70-75 ratings would be what I'd like to see.

Thanks again!

 

75 from Dallas to Denver got 18.5 and just turned 5k miles. Was getting 14 in my old truck heading home in the morning will update when I get back.

 

The laws of physics are the laws of physics- they don't even bend for the highest paying advertiser. IMHO, we're reaching the peak in truck fuel economy with the EB technology. But in the end, it all still grinds down physics- to move 6,000 pounds, you need power. And power requires fuel. Plus the faster you go, the amount of power to overcome wind resistance needs to multiply by four IIRC. I'd believe 25mpg- and that's driving like your setting a world record of pissing off the most motorists in day. 30 needs to take a hike

 

My 5.0 is rated at 27mpg highway, so far my best hwy mpg has been 21 on a 150 mile straight/flat surface, windless, 65 degree day while doing 65mph religiously...
