I run my 14 premium city only, and if im lucky I get 18mpg. I don't even ride it hard. but yeah I've never done Highway driving yet in my 3 months owning it, so idk how high my mpg could get. when i got gas today, I had 16mpg lol that's so bad.

most of my driving is blacktop @60mph, and alittle town, but I've learned to use the gearbox more when I'm driving 60 or less, not much fun but sure helps on the mpg.BTW, I don't beat on it , but I do go thru 1-3 hard 2 times a month LOL-- CHOP
My mileage has improved to 28.3 after installing an Airaid tube & K&N drop-in filter. I know after I tune it it may even get better but I am changing the oil 1st. I'll report back afterwards.

I was told it was a NO TUNE CAI HA, now after talking with a couple Mustang guys, they told me you have to tune after CAI install with the newer Mustang 3.7
So reporting back in on this ancient thread. Car's never done better than ~22 MPG on 90% driving, and that's sort of the high water mark... At 100,000, I think it's "broken in." Mostly what I'm getting from this thread is that engine vary widely on their fuel efficiency and I got one on the lower end of the scale.
