1.0 Ecoboost around 400-410 per tank (though doesn't include what's left in the tank when I fill up). According to my spreadsheet overall miles per tank would be around 480
I'm averaging around 40.8mpg atm, cars done just about 3200 miles...I reckon after a few thousand miles more it will start to rise. This weather doesn't help things! Bring on the summer!
