    ^ I don't keep track. I figured I had more when the last bar starts blinking though! I'll have to be a little more careful. o_O

    Japanese fuel tanks start life as metric i.e.36 L, which is 9.5102 gallons, so you had a bigger margin than you thought! :)

    Have you used this pump before? Could be a faulty pump? I just filled up this weekend and the pump said I put in almost 9 gallons, and when I manually calculated the MPG, it said I only got 48 MPG ( I have never gotten this low mileage). My scangauge and trip meter calculation was 57-60 MPG. It was a pump I don't use regularly and I think it was faulty.

    I've used the pump before, but I don't track my mileage. (probably would be depressing given my "spirited" driving habits).
    hieronymous - thanks, that's really cool info

    Did you go past the first click? That's the major measuring point for the fuel tanks. The C will let you put in almost another gallon after the first click. I've seen 10.4 on some people's fuelly accounts before.

    nope that was at the first click. That's what I meant about not "topping it off". :)

    Cool, some people consider topping off to be when fuel is spilling out. Other people consider topping off to be the second click.

    i've run close to empty before and i got 9.8 or so.. and have seen friends fill up 9.6-9.7 gallons before the pump clicked.

    so i'm wary about the 9.5 gallon capacity rating. granted you should never run that close to empty in the first place, but stuff happens.

    And you also should NEVER go beyond the second click.......because overfilling can damage the vapor recovery system, resulting in an expensive repair.

    NO.
    Because I visit forums like this to learn from the mistakes that others make.
    And to relate the mistakes I make to try and help others.

    That is one that I learned from others; not one that I did personally.

    Kinda sounds like I offended you somehow. I'm just curious, I've read about this and never met anyone who experienced damage to their vehicle. That's why I asked.
    I can see how fuel might possibly leak down the evap line to the charcoal cannister.

    That's exactly what happens and once the canister is full of gas, there is no way to "fix" it short of replacement.
    Since you really aren't gaining anything by doing it in the first place, I don't understand why people do it at all.

    And sorry for the attitude. I've run across FAR too many people who think the only to know about anything is to experience it first hand.

    I've been reading about this so-called canister failure and in the 20 years of working on cars, I have only ever heard of 1 canister ever failing... fyi... it had nothing to do with over-filling the gas tank.

    In my experience the reason I did it in my old car was because it had a tank mileage range of 350 miles. If I didn't fill up the tank to the brim and only stopped at the first click I would only get 300 miles max. I filled that up ever 3 days vs every 4 days. Over time that adds up. That car went 180,000 miles and never had any issues with the fuel systems.

    Your mileage may vary.
    That can apply to a lot of things.

    Just because you have never seen it doesn't mean that it doesn't happen.
    And just because it happens to one person with a particular model vehicle doesn't mean that it will happen to all.

    Not many people put on the mileage that you do I suspect and for most getting in an extra gallon of gas
    won't make a significant difference to anything.

    I don't think it is worth the risk.
