    Was a warm day, one bar left, 11.3 gals filled up. Just one top-off and gas overflowed. Never was any burp and gas stayed at top of the neck. Has this happened to anyone else?
    (Usual fill-up is 9.5 gals)

    Faulty pump nozzle, or the nozzle was not inserted far enough into the car's fill pipe. (BTW: don't top off. Topping off greatly increases emissions of unburned hydrocarbons which contribute to smog.)

    I had a gas spill on my 2nd fillup.

    From one non-flashing bar, the pump kicked off at around 8 gallons, and I kept it going to around 11.2. Then I noticed there was gas squirting out around the nozzle.

    I pulled the nozzle out and out came this torrent of gas. Whoops.

    On the flip side, I managed 600 miles on that tank... but for #3, I hit 9.2, topped up to 9.6, and left it at that.

    I used to get no more than 15 into my Accord's 17.1, so eh, whatever. :)

    I've read somwhere on this site that it's not recommend to Top off. Does it harm the car in anyway? I usually never top off and I stop when I hear the pump click. What are your thoughts?

    There's a quote from John's Stuff that says it better than I could:

    The Bladder Question.
    You cannot squeeze gas into a tank with a bladder. Doing that causes pressure, so when you remove the pump it relieves the pressure and the gas squirts out. Also note that you are defeating the emissions system by overfilling. Besides the obvious spill on the ground, the not-so-obvious is that you filled the charcoal canister within full of gas. That makes the capture of evaporates the bladder couldn't prevent impossible, since it is now totally saturated with gas. So, don't ever top off after the pump automatically stops. Just put it on the slowest setting and let it determine where full is. And remember, there is always the possibility that you will pick a pump with a broken sensor. So keep an eye on how much is pumped. If it goes beyond what you were expecting (yet another benefit of the Multi-Display), just stop the pump yourself.

    Yes, I've had the same problem. I was filling up slowly when it happened. It is a new 2007 and it was only my third fillup. Anybody have any ideas how to prevent this? I do not want to ruin the paint.

    The only way I know is to fill at the slowest rate, stand by the tank, and don't top off when the pump shuts off.
