    I am not the expert but I do not recall any past posts saying the O2 sensors or bad cat as the cause of low Prius MPG. For example,somewhere we have a low MPG checklist. Maybe O2 sensor is on there, but I do not recall it coming up.

    Normally we say first step is check 12v battery, for everything.

    I just filled up tonite and lost first pip right away. Got 5 gals in there with 2 pips showing less than 20F outside.

    ...and that is absolutely wrong.
    When it starts to fail, the cat converter can, and often does, have a dramatic impact on fuel mileage.

    Only when necessary.

    No you weren't. 5X20 is 100.
    If you really think you were getting 100 MPG, then we are discussing the wrong problem here. ;)

    Check out post 25.

    Her car needs to go into the shop, throwing parts at it is not the answer.
