I don't own an Outback, but Fuelly says that based on over 5 million miles of driving, the MPG most people are getting in the 2.5 CVT is 25.21 MPG, which is about what you are getting. EPA rating is 24 MPG combined. Did you do any recent maintenance or are you running winter gas? Weather is a factor, too. Did you change your commute? Sitting with the car on kills gas mileage on cars that don't have the auto start-stop feature.
