Anyone else have an issue with gas mileage? I have a 2010 WRX with 2500 miles. I get 15 MPG driving very light footed around town, 20 highway, driving 65, even less at 70. Engine rev’s high (3000 RPM at 70), lack of a 6th gear. Is there any way to tune (or de-tune) the engine to be more efficient?
My previous car (Civic SI got over 30 MPG).
