I managed 40.2 MPG using every last gram of patience I had following tractor trailers on one of my drives home for 120 miles from Sacramento, CA to the San Jose area in my 5-speed manual XV Crosstrek...
Do you have a Lineartronic CVT or manual transmission? I would imagine probably the CVT since it is far more capable of high MPG.
