I'm always surprised at the mileage people say they are getting. Mine's a 2008UK (85,000 Miles) and I always endeavour to drive in the optimum Prius way where possible. My MFD over a long period usually shows between 62 and 65 mpg which is considerably higher than some others are quoting. What's the general consensus as to the percentage of accuracy of the MFD readings? I should also add that it seems a bit better since the new cat and new 12v battery - although whether this has any bearing, I don't know.
