    this is only my 2nd tank since owning the Prius. on screen, it averaged 55.8 and the fill up after was 9.4 gallons so 53 ish is actual MPG. however, i'm fed up with babying the gas pedal. i can't stand driving like an old man. i think i'll put up with a slight decrease in MPG in return for a "normal" driving habits. keep in mind, my previous two cars were STI and 04 M3. so it's a big change for me...

    on a side note, i just put in 91oct, i'm hoping 91 will give me better MPG, we'll see..

    i drive pretty normal without babying the throttle, and doing 75-80 on the freeway and still have no problem getting 51-52mpg. those tanks were my normal driving tests. now i'm gonna hit up eco mode and see what i get.
