So far with my truck and no mods, I get 16.5 driving slow in town and 23 driving on the highway with the cruise set at 68.

 

I swear, with the way I drive, in town, I'm getting 10 mpg at the best in my 2002 5.4L. I haven't done any calculations to find out for sure, but today I drove approx 20 miles and I think the needle moved less than when I drive 2 miles through town.

 

I'm with you FX4offroad...I have a 2002 4.6 and in town I get around 11-12, and I drive very conservatively.

 

Steady on the go pedal, 2013 ecoboost screw xlt with 3.31 gears and 6.5' bed 4x4. Not bad for the first couple thousand miles I think.

 

Picked up my new Super Crew EB with 3.55 today. On the way home I only got 15 MPG with cruise set anywhere from 75 to 78 mph. Display showed 16.1 mpg. This was 300 miles of pure hwy mileage. Some people are posting up really good numbers and thought I would get better myself. Oh well, I hope the numbers go up as it breaks in.

 

A long-time Toyota buyer here, and just bought my first American-badged vehicle in 7 years.

Drove to San Diego to pick up my "new" 2010 F-150 FX4 Supercrew 4x4. It's got a 6" Pro Comp lift kit and 35" Toyo tires...on the drive back to Yuma I was expecting about 13-14 MPG and at one point was at 10.9! When I drove it to Phoenix yesterday I did some "tests"...at 75 mph on the speedometer (which was actually 81 mph) I got 10.6, at 70 I got 12 mpg, at 65 ( got 13.5 and at 60 I got 16.5.

I'm new to this forum and have read with interest some of you long-time Ford owners' solutions to getting better gas mileage...just seems counterintuitive to buy a beast like this and then have to hypermile to get remotely acceptable gas mileage.

I sold my '09 Tundra 4x4 Crewmax Rock Warrior in April because of the crappy gas mileage, and it turns out it was better than my new F-150!

Now what?

 

Engine break-in rules haven't changed. Vary your speed and don't use cruise control to set the motor at top end for the first 500 miles. You probably should be taking it over 60-65 much yet.

On another note, mileage improved for me (and many others on here) once the engine was broken in. You'll get better mileage if you keep it below 70 in any case.

Cheers,

 

Drop the lift, drive slower, and put passenger tires on it. Your mileage will improve dramatically! Otherwise, be happy driving around a pretty bada** modified truck that gets horrible mileage.

 

 

I enjoy thus truck more all the time. I bought it in late November and I'm in the Midwest. If mileage gets better with warm weather, can't wait for spring! Here's what it had @ 2k and 3k miles.
