I track mileage with Fuely. I range between 17L/100KM (14USMPG) to 22L/100KM (10.5USMPG) when tracking with Fuely. Most of my driving is in the city and a lot of it is on fun twisty roads and I am usually in second gear at higher RPM.

Reset you MPG stats in the car and try another few tanks and see if you are still way out. I did have issues with failing front O2 sensors that had not set codes but dragged my mileage down quite a bit.

Cheers,
