Can you remind me what harm is done to a car when the gas tank is overfilled?
I remember once hearing a Car Talk caller who had problems due to overfilling, and so I have been careful to buy only the amount of gas I judge I need by my gas gauge, and not let station attendants "top it off".
My husband tells me this is ridiculous. But yesterday he pumped gas for me and actually let the tank overflow because the pump's stop-mechanism wasn't working. He says that no harm will be done if it happens only once, but I don't believe him.
My husband says he overfills the tank on his truck often, and it does no harm. But his truck has $0 resale value, while my car is pretty valuable. Who is right, and what remedial care do I need for my car after the overfilling?
