AVIS rental from LAX - cannot decline gas prepayment option

Question

We travelled to LA last month and rented from AVIS for a week. When we got to the counter, they had the vehicle we had rented and started the rental agreement. We declined insurance coverage and that was fine. However, although we declined the gas prepayment option, we were told there was no option to decline and we had to agree but if we brought the car back with a full tank of gas, the charge would be removed.

When we returned the car, there was a long line of returned cars and no one to check us in. We were told to leave the keys in the car and would receive the confirmation by email. After trying to find someone, we left for our flight. We got an email that they had charged the entire amount including the gas tank charge. My husband called the next day and they asked us to send supporting documentation. Luckily we had saved the gas receipts and taken a picture of the dashbaord with the gas tank full when we returned the car. After about a week we called again and they reimbursed us for the additional amount.

So my advice is insist on declining the gas prepayment option. If not possible, save gas receipts and take a picture of the dashboard if no one is there when you return. It is a hassle but apparently it is not unusual.

Answer

When renting a car from AVIS at LAX (or other major airports), it is important to be aware of the gas prepayment option. Many customers have reported that the system may automatically include this option, and counter staff can sometimes tell you that it cannot be declined at the time of rental. However, you should be able to avoid being charged if you return the vehicle with a full tank of gas.

Here are some key points and practical advice based on experience:

Check the rental agreement carefully: Even if the counter agent says the gas option cannot be declined, confirm on the agreement whether the prepayment is listed as optional.
Refuse or document: If possible, insist on declining the gas prepayment. If you cannot decline, make note of it, and take photographs of the dashboard showing a full tank when picking up and returning the car.
Save receipts: Keep all gas receipts from fuel you purchased. This can serve as proof if the charge is mistakenly applied.
Returning the car: If there is a long line or no attendant, park the car in the designated area, take a photo of the fuel gauge, and leave the keys as instructed.
Follow up: Check your credit card or bank statement for the gas charge. If charged incorrectly, call AVIS immediately, provide your documentation (receipts, dashboard photos), and request a refund. Persistence is often needed.

Additional tips:

Use a phone or camera to capture a clear image of the fuel gauge at both pick-up and drop-off.
If using a full-to-full policy, make sure to refill the tank completely at the same type of fuel specified in the rental agreement.
Document the return location and date/time in case of disputes.
Consider taking a quick video when returning the car if no staff are present, showing the full fuel gauge.

While this process can be a bit of a hassle, it is common for airport rentals. Being proactive and keeping clear evidence helps ensure you are only charged for what you actually use, avoiding unnecessary prepayment charges.
