I have only had mine for little over a week. I have already taken it on a road trip, roughly 1,100 miles. Averaged 19mpg, not great. I was pushing it some to see what it would do. Several hours of city driving, and its not even broke in.
In my experience a turbo motor likes higher octane fuel...
Little over 1k miles for the trip. Badlands trim package. Figured out the first night I needed some ambient lighting. First vehicle I've had in a long time that didn't have it.
Bought mine last week. Already have took it to NYC. Wasn't sure I would come back with fenders, but she survived.
Very comfortable ride, averaged about 18.5 mpg on new engine.
