i always shut my car off, but then again i shut it off anytime i'm setting still for any legnth of time putting fuel in and burning fuel at the save time doesn't make a ton os sence to me. just my oppinions.
i didnt' read all the posts before me but theroitacally (thats spelled wrong isnt' it) it is possible for a spark to light the gas fumes from the pump. posible from the fuel pump or the chance of a electrical short, 1 in a million chance but COULD happen. but that could happen anywhere. i don't see any big probem with leaving a car running while filling it up, somethign could happen from leavign the car running, but its just as likely that you will have some static electricity built up in your clothes and that will spark some fumes and cause an explosion.
