Wife gets about 25/26 MPG around town
We have a worst-case scenario drive around our house (lots of speed bumps and stop signs/stop lights), so that is a realistic minimum. On a mostly highway mileage trip last year, we got about 33 MPG.
The vehicle has the 1.4 turbo with the dual dry clutch auto transmission.
We ONLY use premium octane gas, but I have not been able to find a gas station around me that uses dedicated hoses for the different grades, so I assume there is some mixing going-on?
