Mine says the same.
I feel like a noob, I've been trying to get my gas mileage for 800 or so miles says 27.2 on 830 miles haha. I just took a 20.2 mile adventure to the dealership, 35.2 mpg driving city wise on main roads there hardly stopping for lights, no a/c. On my way back had a/c on and hit nearly every light and still managed 34.3 averaging 40 mph there and back. I can't wait to go on a 2 hour drive to my dads to put it to the test!
