Are you guys all serious? I just purchased my 2010 ES a few weeks ago (not CPO) w/ only 32k miles. No matter what I do i cannot get the thing to give me better than about 21mpg according to the display (not my own calculation).
I checked the service history for the car (thru lexus) and a 30k service was done on the car at the lexus dealership. Any ideas/suggestions on what sorts of things could be causing such low mpg?
