Quick Summary:

Picking up a car hire in New York and nipping into New Jersey can feel straightforward until you stop for fuel. Suddenly there is an attendant at your window, you are not allowed to touch the pump, and the card reader does not behave like the pay-at-pump terminals you might expect. For UK visitors, the good news is that it is easy once you know the script, the payment quirks, and a couple of practical steps to avoid misfuelling and card authorisation surprises.
If your trip includes Newark Airport, it helps to plan ahead because many travellers refuel close to return time. If you are comparing options around the airport area, these Hola Car Rentals pages give you an overview of New Jersey and Newark pick-up points: car hire at Newark Airport (EWR) and car hire in Newark (EWR).
Why you cannot pump your own fuel in New Jersey
New Jersey is the notable exception in the US where self-service at petrol stations is not the norm. State law requires fuel to be dispensed by a station employee in almost all circumstances. That is why you will see “Full Service” signage and why the attendant may wave you back if you step out to reach for the nozzle.
For a visitor, the practical impact is simple. Pull up, stop with your fuel cap aligned to the pump, stay in the car unless asked otherwise, and communicate what you need through the open window. It can feel awkward the first time, but it is routine for locals and attendants are used to out-of-state plates and rental cars.
What to say at the pump, a simple script
In New Jersey you are effectively ordering fuel, not operating a machine. Most interactions take less than 20 seconds.
Step 1, tell them the grade: Say “Regular, please” unless your car hire agreement or fuel flap indicates otherwise. In the US, regular is typically 87 octane and is fine for most standard petrol cars.
Step 2, tell them how much: You have two common options. If paying cash, say a fixed amount, for example “Twenty dollars, regular.” If paying by card, say “Fill it up, regular, paying by card,” or request a specific amount if you want to control spend.
Step 3, confirm payment method: Hand over your card when asked, or pass cash. The attendant will usually return your card and provide a receipt. If you want a receipt for expenses, ask “Can I get a receipt, please?” before they walk away.
Step 4, know your cap location: Many UK drivers are used to a consistent fuel cap side, but US models vary. Check the little arrow next to the fuel icon on the dashboard, it points to the side with the cap. That helps you pull in cleanly without needing to reverse and re-queue.
Which payment methods work best for UK visitors
Payment at New Jersey petrol stations is generally easy, but it differs from UK pay-at-pump in ways that can surprise travellers using a car hire across state lines.
Credit cards: A credit card is usually the smoothest option. The attendant may take it to the terminal, or there may be a handheld device. You might be asked for billing ZIP code when paying at a pump in other states, but in New Jersey the attendant-run terminal often avoids that prompt.
Debit cards: Debit can work, but you may be asked to enter a PIN, and some terminals are fussier with foreign cards. If a terminal requests a ZIP code and you do not have one, a common workaround is to try “00000”. It does not always work, so having a backup card is wise.
Cash: Cash is widely accepted and can be the simplest way to avoid authorisation holds. If paying cash, you typically prepay an amount. If the pump stops short of the amount, you may be given change. If it hits the amount and the tank is not full, you can add more.
Mobile wallets: Apple Pay and Google Pay acceptance varies by station. Do not rely on it as your only method, especially if you are refuelling close to a return deadline.
If Newark is your return point, planning fuel stops becomes part of the logistics. These pages can help you orient around suppliers and vehicle types near EWR: Hertz car rental at Newark (EWR) and Avis car hire at Newark (EWR).
Avoiding misfuelling, petrol vs diesel in US terms
Misfuelling is one of the easiest ways to turn a simple refuel into a costly delay. It is also more likely when you are tired, driving an unfamiliar car hire, and reading unfamiliar labels.
Know the wording: In the US, petrol is labelled “gas” or “gasoline”. Diesel is usually clearly labelled “Diesel” on the pump and often has a green handle, but handle colours are not a guarantee everywhere.
Know your car: Most New York car hire vehicles are petrol. Diesel cars exist, but are less common than in the UK. Before you leave the pick-up location, check the fuel type printed on the rental paperwork, the fuel cap, or inside the filler door. If it says “Unleaded only”, it is petrol.
Watch the attendant, politely: You do not need to hover, but it is fine to keep an eye on the nozzle they select. If you realise they reached for diesel and you need petrol, speak up immediately, “Sorry, regular unleaded please.” Attendants prefer a quick correction before dispensing begins.
Do not confuse grades: “Regular” is the default for most cars. “Mid-grade” and “Premium” cost more and are unnecessary unless the car specifically requires it. If your vehicle requires premium, it is usually stated clearly near the fuel filler and in the car’s manual notes.
Authorisation holds and why your card total looks wrong
Even when the final fuel cost is modest, your banking app may show a larger temporary amount. This is not unique to New Jersey, but it is worth understanding so it does not look like double charging.
What is happening: When you pay by card, stations may place a pre-authorisation hold to ensure funds are available. The hold can be significantly higher than the amount dispensed. After the transaction settles, the hold drops off and only the real fuel total remains.
How long it lasts: Holds can clear quickly or take a few days, depending on the station and your card issuer. If you are travelling with a tight budget, this can reduce available balance temporarily.
How to reduce surprises: Use a credit card rather than a debit card if possible, because holds affect your current account balance more directly. If you want to cap spend and avoid a large hold altogether, pay cash for a set amount.
Practical tips for a smooth stop, especially on a return-day drive
Choose a quieter moment: Stations near highways and airport corridors can be busy. If you are returning a car hire to Newark, refuel earlier than you think you need to, so you are not queueing under time pressure.
Open the fuel door before they arrive: Some cars have a lever, button, or central locking interaction. If you can, pop the fuel door as you roll to a stop, so the attendant is not waiting while you figure it out.
Know your fuel policy: Many rentals are “full to full”, meaning you collect with a full tank and return full. Keep the receipt in case there is any dispute about level at return.
Ask for the amount before you tap: If the attendant is processing on a handheld, you can ask, “What is the total?” before you confirm. It is normal to check.
Tipping: Tipping fuel attendants is not required in New Jersey. Some locals tip a dollar or two for exceptional help, but it is not expected for routine refuelling.
What changes when you cross back into New York
Once you drive back into New York State, self-service is common and you will often pump your own fuel, pay at the pump, and deal with the ZIP code prompt more often. That difference can feel abrupt on the same trip. If you are continuing into other states, expect self-service to be the default almost everywhere else.
If your itinerary includes both New York and New Jersey, it can help to decide where you would rather refuel. Some drivers prefer New Jersey because full-service is convenient, others prefer self-service because it gives them direct control of the nozzle and payment terminal.
FAQ
Why is New Jersey attendant-only for petrol? New Jersey law generally requires fuel to be dispensed by station employees. It is a long-standing rule, so self-service is not the usual option.
What should I say to the attendant with a car hire? Say the grade and the amount, for example “Regular, fill it up, paying by card,” or “Regular, twenty dollars cash.”
Will my UK card work at a New Jersey petrol station? Most UK credit cards work well. Debit cards can work but may request a PIN or fail on some terminals, so carry a backup payment method.
Why does my banking app show a bigger fuel charge? It is often a temporary pre-authorisation hold. The final posted amount should match the fuel dispensed once the transaction settles.
How can I avoid putting the wrong fuel in? Confirm the car’s fuel type on the fuel flap or paperwork, then request “regular unleaded” unless premium is required. Watch the nozzle choice before pumping starts.
