    I have a quesiton for those driving the new Prius, or even the older Prius models. Do you ever compare your gas fill ups to your mpg on the dash computer? I was supposed to be getting around 47.5 (mixed driving and new car under 800 miles) and when I gassed up again, I found my true mpg was closer to 44.5.<br/><br/>This is not an uncommon finding for me as I have gotten similar computer based mpg that don't match up to reality.<br/><br/>Any comments from other drivers? I have also heard mpg improves the more you drive and the closer you get to the first 10K on the car.

    My calculated vs displayed mpg has settled in on a 7.5% error. I'd assume it's a purposeful tweak by Toyota: just enough that they can have more positive press, not so much that everybody's doing this: :rolleyes:

    It's irritating, you get used to it.

    We have lots of threads on this. Yes, the dash display is 'optimistic'.

    There may be a bit of improvement as the fresh tires wear in. Other than that, nearly all improvement will be from "better adjust of the nut behind the wheel", i.e. improvements in driver technique.

    There are numerous posting about how to get better MPG. My favorites are over at CleanMPG.com, where I started before PriusChat. Here is one:
    Beating the EPA - The Why’s and How to Hypermile | CleanMPG

    Others have different favorites here on PriusChat, some listed in their signatures. I can point to only a few:

    I get EPA MPG spot on for a v wagon. I use no special technique beyond moderation. I do use ECO mode for throttle input response and Auto for HVAC. I calculate the MPG over many tanks (see below) using fuelly.com to allow for variations in driving conditions, pump nozzle shut off, etc.

    Moderation to me means generally doing the speed limit, quick driver response at a stop light but not trying to beat anyone, cruise control on the highway.

    They post in a Prius v forum, yet claim to have a Japanese domestic Prius c. That does seem odd. i seriously doubt there even is a Touring version of the c in Japan. There is not one in the US.

    They refer to the new Prius but neither the v or the c have seen a new generation since their 2012 introduction. You almost think they are referring to the Liftback.

    They are completely unaware that the Gen 3 computer tends to be over 5% off. (Gen 2 was not that bad, nor is my v)

    And to answer the OP, I use Fuelly.com to second guess my onboard computer, they are about 1 MPG different.

    It is also strange there are 7 days between registering & first posting.

    Many post on the same day they register. You can lurk without registering. I know I did.

    That isn't strange at all. A few don't even post in their first year.
