I've had mine a week. When I got it, it was 4 months old and had done 900 Miles. Computer said 35 MPG. I've only driven it from the house to work, 10 miles each way, 30 or 40 MPH through the villages with a small section of 60 limit. I reset the computer when I filled the tank the day after I got it. Now showing 45 MPG, I had to work quite hard to get there, still experimenting with whether 40 on the level should be 5th or 6th gear.
