Avis Fuel Policy 2026: Refueling Fees Explained
Avis offers three fuel options, each with its own pricing trap. Avis does not publish its per-gallon refueling charge, but travelers report about $9 to $10 per gallon. EZFuel is a flat $17.99 fee ($18.99 in California) for trips under 75 miles, waived if you show a fuel receipt, 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. | Reported ~$9-$10/gal if below full (varies by location) |
| EZFuel (flat fee) | Drive fewer than 75 miles and pay a flat $17.99 ($18.99 in California) instead of refueling. Removed if you show a fuel receipt. Not at all locations. | Costs more than the 2-3 gallons a short trip uses |
| Fuel Service Option (FSO) | Prepay for one full tank at pickup at rates comparable to local pump prices. | $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. The $9.50 refueling figure is a typical reported rate, not a published Avis price:
No fuel receipt: $17.99 flat EZFuel fee ($18.99 in California)
Self-fill instead: 2.5 gal × $3.65/gal = $9.13
EZFuel only applies when you drive fewer than 75 miles, so the case above (returning a 16-gallon tank half-empty) cannot happen under EZFuel. Avis removes the EZFuel charge if you show a fuel receipt.
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 refueling charge, EZFuel 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. Both publish the same EZFuel fee ($17.99, or $18.99 in California, for trips under 75 miles) and describe prepaid fuel as comparable to local pump prices. Neither publishes a per-gallon refueling rate, so compare the rate on your agreement rather than assuming one brand is cheaper.

How to avoid Avis's refueling fee
- Photograph the fuel gauge at pickup. Proves your starting fuel level in case of dispute.
- Decline EZFuel and FSO unless you have a specific reason to choose them (EZFuel: a trip under 75 miles with no time to refuel; FSO: returning nearly 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.
Renting an EV from Avis?
Avis's EV terms say the car must be returned with a battery charge of at least 70%. If you return it below 70% but above 10%, Avis charges a $35 charging fee. Below 10%, an additional $35 low charge fee applies, for a total of $70. Photograph the battery percentage at pickup and at return.
International Avis rentals
Avis operates in 165+ countries. Fuel is charged per liter in most markets, and rates vary significantly. In the UK, the refueling charge is typically £2.50-£3.50 per liter - the equivalent of $12-$17 per gallon. FillItRight auto-detects units and currency for international rentals.
Frequently asked questions
How much does Avis charge for refueling?
Avis does not publish a per-gallon refueling rate; the refueling service charge is set out in your rental agreement. Travelers report about $9 to $10 per gallon, roughly 2.5 to 2.7 times a $3.65 pump price. On a 15-gallon tank returned half-empty, that is approximately $68 to $75.
What is Avis EZFuel?
EZFuel is an optional flat fuel charge for short trips, not available at all locations. If you drive fewer than 75 miles, Avis charges a flat $17.99 ($18.99 for rentals in California) instead of a per-gallon refueling charge, and the charge is removed if you show a fuel receipt. If you drive 75 miles or more, the flat fee does not apply and fuel is charged under the terms on your rental agreement.
What is the Avis Fuel Service Option (FSO)?
FSO lets you prepay for one full tank at pickup at a rate Avis says is comparable to the current local retail pump price. You can return the car at any fuel level with no refueling charge, but no credit or refund is given for unused fuel. FSO is only cheaper than self-fill if you return the tank nearly empty.
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 and publish the same EZFuel fee and the same EV return rule (70% or more). Neither publishes a per-gallon refueling rate, so check your agreement.
