Landing at Los Angeles for car hire often means moving quickly through the pick-up process, especially at busy times. Fuel is one of the most common areas where customers feel unsure, because the online booking may include a prepaid fuel product, while the rental desk may still talk through fuel choices and present a contract with additional line items. The key point is that the desk can offer an option, but you do not have to accept a second fuel product if you already prepaid online.
This guide explains when a desk fuel offer is legitimate, when it becomes a duplicated add-on, and how to confirm the fuel terms in writing before you sign. It also shows what to look for on the rental agreement, so you can stop a prepaid fuel purchase turning into two separate fuel charges.

Why a fuel option can still appear at the desk
Even if you prepaid fuel online, the desk agent may still talk about fuel. This happens for a few practical reasons:
Different products have similar names. “Prepaid fuel”, “fuel purchase option”, and “prepay and refund” can mean different things depending on supplier and location. A desk offer might be a different product to what you already bought, or it might duplicate it.
The desk must confirm what is on the agreement. The rental contract is the document that controls what you are paying at pick-up. Agents often review fuel, insurance, deposits, and return conditions with every customer, whether or not items were prepaid.
Local systems do not always import third-party prepayments neatly. When you arrange car hire through a broker or travel site, some items appear on the voucher rather than the supplier’s own system. That does not automatically mean you should pay again, but it does mean you need to reconcile voucher versus contract.
Fuel policy can be tied to how the car is returned. If your online prepaid fuel assumes you will return the vehicle empty, but the supplier location requires “return full”, the desk may push an alternative. This is rare, but it is exactly why written confirmation matters.
Understand the most common fuel policies
To spot duplication, you need to recognise what each fuel policy looks like in plain language on a contract:
Full to Full. You collect the car with a full tank and return it full. If you return it less than full, you pay for missing fuel plus a service fee. There is no reason to pay for fuel upfront under this policy unless you choose an optional add-on.
Prepaid Fuel (Full to Empty). You pay for a full tank at pick-up and can return the car with any amount left, usually with no refund for unused fuel. If you already paid online for this, the contract should show it as included or already paid, not as a fresh charge.
Prepay and Refund. You pay for a full tank upfront, then receive a refund for unused fuel when you return. Some desks call this “prepaid fuel with refund”. This can be confused with full to empty.
Return Empty / Fuel Purchase Option. Similar to full to empty, and often non-refundable. Wording varies, so focus on whether it states “refund for unused fuel” or “no refund”.
Refuelling Service Charge. This is not a fuel option you want to buy twice. It applies if you bring the car back short of fuel on a full-to-full agreement, and it is typically expensive.
At Los Angeles pick-up, the important task is to match what you prepaid with the exact policy on the agreement in front of you.
How duplicated fuel add-ons usually happen
Duplicate fuel charges tend to come from one of these scenarios:
1) Prepaid fuel on voucher, fuel purchase on contract. Your voucher states “prepaid fuel included”, but the desk prints a contract line such as “FPO” or “Fuel Purchase Option” with a dollar amount. If you sign, you may pay twice, once online and once at the counter.
2) A fuel option is bundled into a “package”. Sometimes the desk offers an upgrade bundle that includes fuel, toll products, or roadside assistance. You might accept the package for one element and not notice it also adds a fuel purchase.
3) The agent changes the fuel plan to resolve a return-time constraint. If you have an early return flight and the agent suggests it is “easier” to buy a tank now, make sure it replaces, not adds to, what you already paid for.
4) A hold or estimated fuel amount looks like a charge. Some agreements show a fuel amount as an “estimated” item for deposit calculation. That should not be collected as an extra paid product, but it can look similar. Ask the agent to clarify whether it is a paid item or an estimate.
What to check on the contract before you sign
Use a simple cross-check between three documents: your booking confirmation, your voucher, and the rental agreement on the counter.
Step 1: Find your prepaid fuel proof. Look for wording such as “prepaid fuel”, “fuel included”, “fuel option paid”, or a separate fuel line item that is marked paid. Keep screenshots available, because airport connectivity can be patchy.
Step 2: Locate the fuel section on the rental agreement. Most contracts have a dedicated “Fuel” box or a list of optional products. Search for abbreviations like “FPO”, “FUEL”, “PREPAID”, “FULL TANK”, or “REFUEL”.
Step 3: Confirm the policy and the payment status. You want the agreement to show either full-to-full with no prepaid fuel charge, or a prepaid fuel option that is clearly included and not recharged. If there is a price next to a fuel product, ask whether it is being charged today.
Step 4: Watch for two fuel lines. The clearest red flag is two separate references, for example “Prepaid Fuel” plus “Fuel Purchase Option”, or a fuel package plus a refuelling product. If both appear, pause and ask for a revised contract.

How to ask for fuel terms in writing, without conflict
Desk conversations move fast, and verbal assurances are hard to rely on later. A calm request for written confirmation is normal and often welcomed. Use clear, factual wording such as:
“My booking includes prepaid fuel. Can you please show that on the agreement as already paid, with no additional fuel purchase?”
“Before I sign, can you print or mark the contract to confirm the fuel policy is full-to-full?”
“If you are changing the fuel plan, can you confirm what happens to my online prepaid fuel, and where that is recorded?”
The aim is not to debate the desk agent. It is to ensure the signed document matches what you intend to pay.
If the desk insists the prepaid fuel cannot be honoured
Most of the time, it is simply a contract correction. If you are told the prepaid fuel is not valid or “not in the system”, do the following before accepting any new charge:
Ask which fuel policy applies if you do nothing. If the default is full-to-full, you may prefer to proceed on that basis and avoid paying for fuel twice.
Ask whether the desk can remove the online prepaid fuel from the booking. If they want to sell you a fuel plan locally, clarify whether your earlier payment will be refunded, and how, and on what timeline. If they cannot explain the refund route, do not assume it will happen automatically.
Request a revised contract that clearly lists only one fuel product. You want a single, unambiguous fuel arrangement. If you accept a new plan, your paperwork should reflect that the earlier product is not being charged again.
Keep copies. Take photos of the final agreement and any desk notes. If there is a dispute, documentation matters more than memory.
Common contract wording that signals a duplicate fuel add-on
Look carefully if you see any of these patterns:
“Fuel Service” plus “Prepaid Fuel”. Fuel service might be legitimate if it is only a penalty for returning short, but if it is being sold as an upfront product alongside prepaid fuel, ask why.
“Full Tank” with a price, when your voucher already shows fuel paid. This often indicates you are being charged again.
“Optional Products Accepted” includes fuel-related codes. Some contracts list accepted add-ons in a compact code list. Ask the agent to decode any fuel-related abbreviations.
“Customer agrees to purchase a full tank at pick-up”. If you already prepaid online, it should instead state that the full tank purchase is included or prepaid, not newly agreed at the counter.
Why this matters more in Los Angeles
Los Angeles traffic, long distances, and the likelihood of driving on multi-lane freeways can lead to higher fuel consumption than visitors expect, particularly with larger vehicles. That makes fuel products more expensive, and it can make duplicated fuel line items more painful. It also increases the temptation to accept “convenience” add-ons when you are tired after a flight. Taking two minutes to reconcile fuel terms before signing can prevent a much longer customer service issue later.
What to do after pick-up if you notice a duplicate later
If you only spot the issue once you have left the desk, act quickly:
Check your paperwork immediately. Compare the signed agreement with your voucher. Identify the exact line item and amount.
Contact the rental provider as soon as possible. The earlier you raise it, the easier it can be to correct, particularly before the rental closes.
Keep evidence of the online prepaid fuel. Save the confirmation email, voucher, and payment receipt. If the online product was sold by a third party, note that as well.
On return, ask for the closing receipt. Confirm the fuel charges and policy on the final receipt before you leave the return area.
FAQ
Q: If I prepaid fuel online, can the Los Angeles desk still sell me fuel?
A: They can offer a fuel product, but you can refuse it. If you already prepaid, ensure the contract shows only one fuel option and that it is marked as included or already paid.
Q: How do I know whether the fuel option on the contract is a duplicate?
A: Compare your voucher fuel wording with the agreement line items. If the contract adds a priced “Fuel Purchase Option”, “Prepaid Fuel”, or similar on top of a prepaid voucher, ask for it to be removed.
Q: What written confirmation should I request before signing?
A: Ask the agent to show, on the printed agreement, the fuel policy (for example full-to-full) and whether any prepaid fuel is included, with no additional fuel purchase charges.
Q: Does full-to-full ever require paying for fuel at the counter?
A: No. Under full-to-full you should not pay upfront for a tank. You only pay extra if you return the vehicle with less fuel than you collected, typically at a higher rate plus a service fee.
Q: What if I signed and later realise I paid twice for fuel?
A: Gather your voucher, signed contract, and receipts, then contact the provider promptly. Ask for a review of duplicate fuel items, and keep copies of all documents in case of follow-up.
