Most over the long road traveling with our Escape (2014 2L AWD) is into the Great Plains states. F L A T lands.
Since owning my new 2014 I've noted that cold weather driving my long distance mileage drops from 27/28 MPG to 21/22 MPG when temps are below 40 degrees. My speed is generally within 5 MPH of the posted limit. Using 87 octane year round. The drop in mileage is always noticeable in cold weather. And yes below 20 degrees it drops off even more.
