Mileage Meter Calibration?
 We have enjoyed our hybrid for 2.5 years and consistently score 22.6 MPG. It doesn't seem to matter how we drive, or if we are towing our RV or not, always the same: 22.6 MPG. Can this be accurate? Of course this mileage is great when towing the RV, but the next tank, without the RV in tow, is EXACTLY the same. How could this be statistically possible? We reset the counter on every tank. Otherwise, we love the car.
