I have a SE Sport with 17" wheels and I got 25 MPG the first few tanks. I now have 10,600 miles on it and I get 32 MPG on average and I don't drive very conservatively. I think you will see a difference as the mileage racks up and as the dual clutches bed in. Maybe at 2,000 miles you will see the 30 MPG mark depending on your driving style.
