Dealer will most likely say it's normal or give it some more miles. I doubt they will even spend the time to plug into ecu for a diagnostic test, unless u have a cel light on. IMO u should give it some more mileage, at least 1500 miles, to see if the mpg improves. Also, try running it on the hwy at less than 70mph for a good stretch at moderate throttle, you should see at least low 20's mpg on pure hwy conditions. My best was about 25mpg
