    "The fuel tank capacity is decreased at low ambient temperature. (decreased by about 5 L (1.3 gal., 1.1 Imp.gal.) at -10C (14F).)"

    I guess that puts that question to rest. When the temperature drops to freezing, your gas tank holds about a gallon less.

    a gallon- or more.

    99% of us will never get the whole 11.9 gallons in to begin with even in nice weather.

    it's a quirk, you get used to it.

    Hi All,

    Yea, I had a direct observation of this. Based on comments about 2006's running out of gas, I decided to fill up right after dropping down to one bar. The first time I did this the one bar showed about 3/4 s the way up to work at 20 F. The tank filled up with 8.2 gallons. The next time the tank dropped to 1 bar I was 3/4 s the way home from work, after a sunny day in the low 50's. The car was sitting out on the blacktop all day, too. The car took 9.3 gallons to fill up.

    My Car really is a 2006 Prius. Ignore the mistake in the header to the left.

    Here are a couple of question for you all...
    If you store your vehicle in a heated garage, and fill up within, say, two mins of leaving that heated garage...
    1. Is the tank going to accept the smaller amount or larger?
    2. If the larger/warm weather amount is possible, will some of the fuel be "pushed" out the filler tube overflow if you then drive in cold weather and tank "cools?"

    Just wondering.
