Well I hope that is it....It can't get much worse..600 miles on the truck so far...So you're saying after a few thousand miles it should be up to a solid 16 mpg?? 
Thanks for the response, I was somewhat disheartened when I read another poster saying he got 21+mpg on the tank of fuel he had leaving the dealership....

I have personally gotten more than 21 mpg out of an ecoboost but I am also a conservative driver. I am curious what mileage I will get after 5k being how even on an unbroken in motor I was getting great mileage.
I have seen post after post of people in your same position that didn't have good mileage until they had a few thousand miles on it. Magic number seems to be between 3000 and 6000 with the avg being close to 5000 hence why I used that number for you as a reference of when it should get better.
Don't fret you got an awesome truck there.

I have the 3.73 LS w/ the base engine.
With your engine's torque, I just can't think of a better ratio.

Hey folks, I'm new to the site here, I found it after buying my new 2011 SCrew Lariat with the ecoboost engine about a week ago up here in northern Minnesota. I went on the net to see what others might be saying / experiencing with their new trucks. I bought mine and took it home about ten days ago. I love the truck, it drives great, and has tons of power. There is only one small problem though::: I have gone through two tanks of fuel, putting on mostly highway miles, and my mpg is 15.5!! This better not continue at that rate or I will be very pissed.... Is there a break-in period needed for the better gas mileage? My dealer assures me that that is the problem. I checked as well to make sure that the parking brake was not on.. (I'm only slightly joking..) I love everything else about the truck, but if this keeps up I will not be happy... Anyone in the market for a slighly used ecoboost??????

It is not only the engine which is very tight and has increased friction, it is also the trans, the axles, the differentials, etc, which need that run-in period, to 'smooth-off' all the rough edges so to speak. On my 5.4 I started to notice a change after the first engine oil change (the break-in oil) and then the most after about 5,000 miles of driving including one long road trip, at freeway speeds, down to SoCal. I would also do some manual (actual gallons and actual miles) mileage checks, independent of the vehicle mileage computer. Also, I have found that conservative driving makes a big difference too, for the purposes of MPG checks. One brief test of the 'performance', on a long steep grade, will send the MPG into the basement.
I am sure you will be just fine! I cannot wait to experience this engine in my next F150. Everything I have heard or read, is nothing but positive; I just wish this motor had been available in Oh-9. But Oh-well, that's how they sell more trucks; leak the neat-stuff out, a little at a time, year after year.

my friend ordered one w/ 3.13 rear diff ratio.
Does it have better MPG w/ 3.13 rear diff ratio or only makes little difference.
and someone here said he got delayed boost w/ lower rear diff gear ratio. it that true?
What I though is that if you got lower gear ratio you should get better MPG.
guys pls give me some ideas.
