I live in Southwest Michigan, it also is not to hilly and I mostly drive country roads with few stops and the interstate when ever I can. And even in the summer I still never hit the mid 30's mpgs. I had a 2011 Feista for a year before I upgraded to the focus and took a little hit for doing it to. I drove the Fiesta like a go-cart/stockcar. And I never seen under 31 mpgs with it and even at 80 mph I still got 40 to 44 mpgs on the trips up north. I don't drive the focus as crazy as I did the Fiesta. That should make up the difference in size and weight difference. the fuel mileage estimites on the window stickers were only 1 mpg difference. It would stand to reason I would at least be close to the same with the same driving mix. I guess I will need to do some checks on the car myself. I think I got a 1/2 bad injector but not bad enough to throw a light on the dash. But I am not quite sure how to test for that and Ford is not willing to help anymore till I get a code to show up. Just really frustrated that they don't do more. They could have at least pulled the plugs and inspected them for sign of problems. I worked for Firestone and pep boys for over 12 years but I'm scared to look at anything, cause they would probly blame everthing on me. Well I talked enough.
Just curious... do you usually set the car on cruise and, if so, how fast?
My best mileage has been on two long highway trips.
#1 - all highway, cruise at 65 MPH, possibly slight tailwind, premium 93 octane, 45.0 MPG over 486 miles
#2 - highway and country roads, cruise between 55-65 MPH, not sure on winds, premium 93 octane, 41.8 MPG over 492 miles
