A €100 amount appearing after you use an Italian self-service fuel pump is usually a temporary card pre-authorisation, not a €100 petrol charge. The Italian petrol station card hold allows the payment terminal to approve your card before it knows how much fuel you will actually dispense. Once you finish refuelling, the station submits the real purchase amount and the unused part of the reservation is released.
This is why you can buy €37 of diesel and briefly see both a €100 pending amount and a €37 transaction in your banking app. The exact display, and how quickly the pending amount disappears, depends heavily on your bank or card issuer.
Why the Pump Reserves Money Before You Fill
At an attended petrol station, the cashier can charge you after the fuel has been dispensed. An unattended self-service pump works differently: it needs confirmation that your card can cover a reasonable maximum amount before enabling the dispenser.
The terminal therefore sends a request for a pre-autorizzazione, or pre-authorisation. Italian operator IP specifically warns customers that amounts of €99, €100 or €101 can appear temporarily after a card payment. Q8 likewise explains that self-service card transactions involve a temporary blocked amount and that the customer is ultimately charged only for the fuel actually purchased.
So €100 is not a national fixed fee. The reserved amount can depend on the station, payment system, card network and transaction setup.
What Actually Happens at a Self-Service Pump
The sequence normally looks like this:
- Park beside the correct dispenser and note its number.
- Go to the payment terminal, often labelled self, cassa automatica or accettatore.
- Insert or present your card as instructed and enter the PIN if requested.
- Select the pump number, sometimes shown as pompa or erogatore.
- The payment system requests a pre-authorisation from your bank.
- Once approved, the pump is enabled.
- Choose the correct fuel and fill the vehicle.
- Return the nozzle properly to its holder so the transaction can close.
- The station sends the amount actually dispensed for settlement.
If the temporary reservation was €100 and you pumped €42.60, the final purchase should be €42.60, not €100. Q8’s current payment FAQ confirms that when less fuel is dispensed than the pre-authorised amount, only the amount actually dispensed is charged. You can check the operator’s explanation on the official Q8 payment FAQ.
Why Your Banking App May Look as Though You Paid Twice
Banking apps do not all display pre-authorisations in the same way. You may see:
- a €100 transaction marked pending or authorisation;
- the real fuel purchase appearing separately;
- your available balance or available credit reduced by the reserved amount;
- the pending reservation disappearing later without showing a separate refund.
The last point causes particular confusion. A pre-authorisation is not usually refunded in the same way as a completed purchase. The reservation is simply released.
Q8 states that the pre-authorised amount is released after refuelling but that the time needed for the money to become available again can vary according to the customer’s financial institution. That means the pump may have completed its side of the transaction while your banking app still shows the reservation.
Debit Cards and Prepaid Cards Can Be More Inconvenient
With a credit card, the reservation normally reduces your available credit. With a debit or prepaid card, it can temporarily reduce money you can actually spend.
That matters if your travel account has a low balance. You might want only €25 of petrol but still need enough available funds for the pump’s larger pre-authorisation request. If the bank refuses that request, the pump can decline the card before you dispense anything.
This can be especially awkward near the end of a holiday, when the same account is also carrying hotel deposits, rental-car deposits or other pending transactions.
If the card is declined even though you can afford the fuel
Do not keep repeating the same payment indefinitely. Instead:
- try a different card with more available credit or balance;
- use an attended station and pay the cashier if one is open;
- use cash where the specific self-service terminal accepts it;
- check your banking app for security blocks or declined foreign transactions.
If you are travelling by rental car, it also helps to know your return fuel requirement before the final driving day. Italy on Foot’s car rental guide for Italy explains why checking the fuel policy at pickup and return matters.
What to Look for on the Screen
Useful Italian terms include:
- pre-autorizzazione / preautorizzazione: pre-authorisation;
- carta: card;
- bancomat: commonly used for debit-card payment;
- erogatore: fuel dispenser;
- pompa: pump;
- importo: amount;
- importo massimo: maximum amount;
- scontrino: receipt;
- annulla: cancel;
- self or fai da te: self-service;
- servito: attendant service.
Always check the pump number carefully before confirming payment. At forecourts where one central payment machine controls several dispensers, choosing the wrong erogatore can create a much more annoying problem than the temporary card reservation.
What If €100 Is Still Showing After You Have Left?
First check whether the transaction is marked pending rather than completed. Then look for a separate transaction matching the amount of fuel you actually bought.
If the €100 figure remains pending, the card issuer is normally the best first contact because release timing can be controlled by the bank after the station has completed the transaction. IP’s official FAQ describes €99, €100 and €101 entries as temporary pre-authorisations rather than real charges and recommends contacting the customer’s bank for clarification. The current information is available on the official IP FAQ.
Keep the fuel receipt until the reservation has disappeared. It gives you the station, date, transaction details and actual purchase amount if your bank needs evidence.
What If You Authorised the Card but No Fuel Came Out?
This is the situation where saving the receipt and identifying the station becomes particularly important.
A pre-authorisation can already have been requested before the dispenser fails, you select the wrong pump, or the transaction is interrupted. If no fuel was dispensed, do not assume the temporary amount on your phone is automatically a completed €100 purchase.
Check for:
- a printed scontrino from the payment machine;
- the pump or dispenser number;
- the station brand and location;
- the date and approximate time;
- whether your bank describes the amount as pending or completed.
Recovery procedures are operator-specific. For example, Q8 states that certain failed self-service deliveries generate a receipt that can be used in its reimbursement process. Other networks have their own assistance and refund systems. Follow the instructions printed at that particular station rather than assuming every Italian petrol company handles failures identically.
How to Avoid a Card Hold Causing Problems on a Road Trip
If temporarily losing access to around €100 would cause difficulty, use a credit card with comfortable available credit or choose an attended payment option when practical. Carry a second usable card rather than relying on one debit card for fuel, accommodation and rental-car deposits.
For a longer driving itinerary, you can also organize the rest of your Italy route so you are not depending on a single rural or late-night fuel stop just before returning the car.
Before driving away from a self-service station, return the nozzle completely, wait for the transaction to finish, and take the receipt when one is available. If your phone immediately announces a €100 payment after you bought much less fuel, check whether it says pending before treating it as an incorrect charge. In most cases, what looks alarming is simply the payment system reserving enough money to let the pump start.
