Avis Fuel Policy 2026: Refueling Fees Explained
Avis offers three fuel options, each with its own pricing trap. The default refueling charge is about $9 to $10 per gallon, EZ-Fuel is a flat $15-$25 fee that looks like a bargain but rarely is, and prepaid fuel (FSO) leaves money on the table if you return with any gas left. This page breaks down all three with real numbers so you know which option actually saves money.
Avis's three fuel options
Avis presents these at the counter and sometimes on the booking screen. The agent's incentive is to sell you an option other than return-full:
| Option | What it means | Cost if not used perfectly |
|---|---|---|
| Return full (default) | Get the car full, return it full. You fuel up yourself. | $9-$10/gal refueling charge if below full |
| EZ-Fuel (flat fee) | Pay a flat fee (typically $15-$25) regardless of fuel level returned. | Only cheap if you return nearly empty |
| Fuel Service Option (FSO) | Prepay for one full tank at pickup at near-retail rates. | $1-$16 of unused fuel you paid for |
The math: all three options compared
A Nissan Altima rental with a 16.2-gallon tank, returned half-empty, at a typical 2026 US gas price of $3.65/gallon:
But EZ-Fuel still means you used 8 gallons of gas the rental company paid for and you didn't reimburse. Avis factors this into the flat fee — it's not free. The comparison only holds if you literally don't drive the car.
4.05 gal of unused fuel lost = $14.38 wasted
Avis Preferred: does loyalty affect fuel policy?
No. Avis Preferred (free tier), Preferred Plus, and President's Club offer free upgrades, skip-the-counter, and Avis Inspector priority — but fuel policies apply equally. The per-gallon refueling rate, EZ-Fuel fee, and FSO pricing are all unchanged by status.
Avis vs. Budget: same parent, slightly different policies
Avis and Budget are both owned by Avis Budget Group, so the fuel structure is nearly identical. Budget typically offers fewer EZ-Fuel locations but charges $0.25-$0.50 less per gallon on the refueling service rate. The Fuel Service Option pricing is near-identical across the two brands at the same airport.

How to avoid Avis's refueling fee
- Photograph the fuel gauge at pickup. Proves your starting fuel level in case of dispute.
- Decline EZ-Fuel and FSO unless you have a specific reason to choose them (very short rental, heavy driving, or returning empty).
- Find a gas station 3-5 miles from the return location. Airport-adjacent stations charge 20-50¢ more per gallon.
- Keep the gas receipt — required evidence if Avis later disputes your fuel level on return.
- Photograph the fuel gauge after filling, with timestamp. Proves the car was full at the moment of return.
- Wait for a return receipt that shows fuel level as full before you leave the lot.

Frequently asked questions
How much does Avis charge for refueling?
Approximately $9 to $10 per gallon for the refueling service charge, applied when you return below starting fuel level. Rate varies slightly by location. Roughly three times the retail pump price.
What is Avis EZ-Fuel?
A flat refueling fee (typically $15-$25) available at some Avis locations. You pay the flat rate regardless of how empty you return the tank. Cheaper than per-gallon refueling if you return very empty, but almost always more expensive than self-fill.
What is the Avis Fuel Service Option (FSO)?
FSO lets you prepay for one full tank at pickup at a rate typically just below local retail pump prices. No refueling charge regardless of return level, but no refund for unused fuel.
Does Avis Preferred waive fuel charges?
No. Avis Preferred, Plus, and President's Club tiers do not waive refueling service charges or discount fuel options.
Can I dispute an Avis refueling charge?
Yes. Photograph the fuel gauge at pickup and after filling, keep your final gas station receipt. Dispute in writing within 30 days. If unresolved, file a credit card chargeback within 60 days.
Are Avis and Budget fuel policies the same?
Nearly identical in structure — both are owned by Avis Budget Group. Budget typically charges $0.25-$0.50 less per gallon on the refueling service rate, but EZ-Fuel and FSO pricing are similar across both brands at the same airport.
