The 7.1 MPG sounds like what I was getting, My display always showed from around that to the mid 9's. I never once filled up where I averaged over 9MPG on a tank. While i expected my mileage to be low as it was 99% town and city driving I never expected this low. I did not drive the thing that hard and am very surprised seeing people here getting much higher in city. Funny thing is I traded in my little 2 seater for a big V8 Lexus GX470 SUV and am now averaging 14MPG in city
