All of them that I use, Sunoco, Citgo, Mobil, and Texaco. I have never
typed an amount into a pump, and if it isn't pay at the pump, I don't
stop. I just swipe the card, push "credit" and fill up.

Right, for aviation fuel you usually get to choose your pre-auth amount
at the pump but not for cars. For credit cards they often only hold $1,
however, I believe the original post was talking about ATM cards. When
I run my ATM at the auto gas station, they require a minimum of $30
account balance or the pump will not turn on.
