Filling the tank...

    I've had my 2005 for a couple weeks now, and tried to fill up the other day. It kept tripping the nozzle shut off, when I knew the tank wasn't full (it added about 7 gallons when the guage was on the last bar). I tried to "top it off", but I'd only get a couple cents worth of gas each time before the nozzle shut off. Kind of irritating.

    After driving about 25 miles(post-fillup), the gas guage dropped to 1 bar from full, so I know it didn't fill.

    What's the trick to "filling" the tank?

    TIA.

    Try searching on "bladder" or "tank" in PriusChat. This subject has been extensively discussed for month after month. Some of the comments will no doubt be informative for you.

    This is a well known peculiarity of the Prius caused by the fuel tank bladder.

    Thanks Charles! I tried searching on GAS and Tank, but no luck. I figured it must have been discussed already.

    What are the temps in your area like?
    I've only had mine two weeks now, and I have filled it up once, was down 6bars and was able to put in 7.64gal. It was about 80 degrees F here when I did that. From my understanding the bladder is somewhat sensitive to temp, not wanting to expand as much in cooler weather.

    The bladder is pretty sensitive to temperatures. In warm weather it is fairly pliable and will expand to its full capacity pretty easily. In the winter it tends to not want to expand and as such makes filling the car up a bit difficult.

    Try filling the vehicle more slowly to allow time for the bladder to expand with the additional volume of fuel you are pouring in.

    Yup, it's getting cold out. Don't worry about it.

    I have filled up about 4 times. and find that if you fill up slowly, there will be no problem. I have averaged about 54 MPG, and the computer agrees with figuring the mileage manualy

    Despite all the information on here - I'm still struggling with this. It's cold here in MN and I rarely can get the tank full. Lots of time, the last bar disappears within a couple of miles. So I share your pain!

    Dude join the club, you are likely to be way colder that I am, even if we do have snow right now (run and hide run and hide). OK we get just a little phrenic when there is one inch of snow around here. Yeah, Yeah, Yeah I know that is not much, but remember we use the God method of snow removal. That is God put it there and God will take it away. More the half the people around here can't drive in any snow at all.
