Budget Fuel Policy 2026: Refueling Fees Explained
Budget's fuel policy is nearly identical to Avis's (both are owned by Avis Budget Group). Budget does not publish its per-gallon refueling charge, but travelers report around $9 to $9.50 per gallon, roughly 2.5 times a $3.65 pump price. For short trips, EZFuel is a flat $17.99 ($18.99 in California) if you drive under 75 miles, avoided by showing a fuel receipt. This page walks through every Budget fuel option, the real math, and how to always come out ahead.
Budget's fuel options
Budget presents these three options at the counter, sometimes pre-selected during online booking:
| 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-$9.50/gal if below full (varies by location) |
| Fuel Service Option (FSO) | Prepay for one full tank at rates comparable to local pump prices. | $1-$16 of unused fuel you paid for |
| EZFuel (most locations) | Drive under 75 miles and pay a flat $17.99 ($18.99 in California) instead of refueling. Avoided if you show a fuel receipt. At 75 miles or more, a per-mile or per-gallon rate on your agreement applies. | Costs more than the 2-3 gallons a short trip uses |
The math: all three options with real numbers
A Hyundai Elantra rental with a 14-gallon tank, returned half-empty, at a typical 2026 US gas price of $3.65/gallon. The $9.25 refueling figure is a typical reported rate, not a published Budget price:
3.5 gal of unused fuel lost = $12.43 wasted
Budget Fastbreak: does loyalty help?
Budget Fastbreak is the free loyalty program that gives you skip-the-counter pickup and ready-to-go vehicles. It does not waive refueling service charges, discount FSO, or change any fuel policy.
Budget vs Avis: small differences that matter
Avis Budget Group owns both brands, so the fuel policy structure is identical. But there are subtle differences:
- EZFuel is the same at both brands: $17.99 ($18.99 in California) for trips under 75 miles, waived with a fuel receipt
- Neither brand publishes a per-gallon refueling rate, so compare the rate on your agreement
- Both describe prepaid fuel as comparable to local pump prices, with no credit for unused fuel
- Both require EVs back at 70% charge or more to avoid a charging fee
- Budget's base rental rate is lower on equivalent car classes (typically 8-15% cheaper)

How to avoid Budget's refueling fee
- Photograph the fuel gauge at pickup. Critical proof of starting fuel level.
- Decline FSO and EZFuel unless your situation specifically requires them.
- Find a gas station 3-5 miles from the return location for cheapest fuel + accurate fill.
- Keep the gas receipt - required evidence in any dispute.
- Photograph the fuel gauge after filling, with timestamp.
- Wait for a return receipt that shows fuel level as full before leaving the lot.
Renting an EV from Budget?
Budget'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%, Budget 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 Budget rentals
Budget operates in 120+ countries. Fuel is charged per liter in most markets. In the UK, the refueling service charge is typically £2.30-£3.00 per liter - the equivalent of $11-$15 per gallon. FillItRight auto-detects units and currency.
Frequently asked questions
How much does Budget charge for refueling?
Budget does not publish a per-gallon refueling rate; the charge for fuel used is set out in your rental agreement. Travelers report about $9 to $9.50 per gallon, roughly 2.5 to 2.6 times a $3.65 pump price. On a 15-gallon tank returned half-empty, that is approximately $68 to $71.
What is the Budget Fuel Service Option?
The Fuel Service Option lets you prepay for one full tank at pickup at a rate Budget 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 is given for unused fuel. It is only cheaper than self-fill if you return the tank nearly empty.
Does Budget Fastbreak affect fuel charges?
No. Fastbreak speeds up pickup but does not waive or discount any fuel charges.
Are Budget and Avis fuel policies the same?
Nearly - both brands are owned by Avis Budget Group. The structure is the same: return-full default, the Fuel Service Option, and EZFuel at most locations ($17.99, or $18.99 in California, for trips under 75 miles). Both require EVs back at 70% charge or more. Neither publishes a per-gallon refueling rate, so compare the rate on your agreement.
Can I dispute a Budget refueling charge?
Yes. Photograph the fuel gauge at pickup and after filling, keep your gas receipt. Dispute in writing within 30 days. If unresolved, file a credit card chargeback within 60 days.
What's the cheapest way to handle fuel with Budget?
Return-full with self-fill 5-10 minutes from the return lot is cheapest in 85%+ of cases. FillItRight calculates the exact gallons to add so you don't over- or under-fill.
