3.5 EB, 4WD FX4, just went over 10k on the odo, getting 20.9 mpg, 90% hwy, 10% city

 

Your response does nothing but underscore what I was pointing out in my post. Are you intelligent enough to understand that?

To the OP. I'm getting about 19 MPG on my 3.5L EB as measured by the lie-o-meter.

 

3.5 Eco 3.55s 4wd 93 Octane all the time 15.5 city. I drive it like I stole it in sport mode all the time. I couldn't be happier. I will be tuning soon hope that helps the fun factor. I could care less about gas mileage. I could have gotten a Prius for that.

 

I'm getting 25-26 highway mpg at 55-60mph and about 18-19 city. I'm really happy with it so far. I read a post earlier from a wise sage who said, "You either get Eco or Boost, but not both."

3.5 EcoBoost, 3.31 gearing, 4x4, S'crew, Lariat, 502A, higher-mpg Blue Jeans color

 

How are 3.5 with the 373 doing on mpg?

 

The window sticker on the 2015 F-150 and the window sticker on the 2013 i had is a little different then the 2011 F-150 Window sticker was.The 2011 F-150 Window sticker i have for the 3.5L Eco Boost 4X4 Super Cab was 15 city[expected range for most drivers 12 to 18 mpg] and 21 highway[expected range for most drivers 17 to 25 mpg].So i guess with the 2011-2014 trucks if you get over 12 mpg city you can't really say it's false advertisement.So i guess what i'm trying to say is you have to read the fine print.
