The gas station is supposed to release the authorization after the real payment clears when you stop the pump. So they should not pile up even if you do many visits in short period of time.

In Finland the has pump firsts ask you to choose how big an authorization you want to do when you enter your card to the slot. It will not allow you to pump more than that and the authorization is then replaced by real charge before you enter you car.

I think that's what the problem was in France specifically, the authorizations don't clear as you expect and then your credit card authorization limit gets hit and when you go somewhere else to get gas and use the same kind, it gets mysteriously declined.

I've only had this specific problem in France. Funny enough my American Express cards worked better than my Visa or Mastercard did.
