Wow. I complain about paying $715 per year for two vehicles - my 06 Canyon and my wife's 10 Focus. Full coverage on both.
Summer 2015 was slightly warmer than the previous summer. The vacuum gauge plus wheel covers helped increase summer 2015 mileage to 38.5 MPG. Winter 2014-2015 was colder than normal, so average mileage dropped to 30.0 MPG.
