Hertz Fuel Policy 2026: Refueling Fees Explained
If you rent from Hertz and return the car below the fuel level you received it at, Hertz refuels it and charges for fuel at a local rate (based on an average of local retail prices) and may add a refueling service fee. Hertz does not publish a flat per-gallon rate, but travelers report totals around $9.49 per gallon, roughly 2.6 times a $3.65 pump price. At that reported rate, a half-empty 15-gallon tank costs about $71. This page walks through every Hertz fuel option, the exact math on each, and how to always come out ahead.
Hertz's three fuel options
When you pick up a Hertz rental, you're choosing between three fuel policies - usually at the counter, sometimes on the booking page:
| Option | What it means | Cost if not used perfectly |
|---|---|---|
| Return full (default) | Get the car full, return it full. You fuel up yourself. | Local fuel rate plus a possible service fee (reported ~$9.49/gal) |
| Fuel Purchase Option (FPO) | Prepay for one full tank at pickup. Return at any level, no fee. Unused fuel is refunded only if you drive 75 miles or less. | $1-$16 of unused fuel you paid for |
| Express Fuel (select locations) | If you drive 75 miles or less and do not refuel, a flat Express Fuel fee applies. Show a receipt for a fuel purchase made during your rental to avoid it. | Fee amount is on your agreement |
The math: return-full vs FPO vs refueling fee
Let's use a realistic example - a Toyota Camry rental with a 15-gallon tank, returned half-empty, at a typical 2026 US gas price of $3.65/gallon. The $9.49 refueling figure is a typical reported total, not a published Hertz rate:
3.75 gal of unused fuel lost = $13.13 wasted
How to avoid Hertz's refueling fee
- Photograph the fuel gauge at pickup. This is your proof of starting fuel level. Hertz sometimes marks cars as "full" when they're really at 15/16, triggering a surprise charge if you return at 14/16.
- 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 Hertz disputes your fuel level on return.
- Photograph the fuel gauge after filling. Timestamp it so you can prove "full" at the exact moment of return.
- Ask the return agent to note the fuel level on the return receipt before you leave the lot. Don't drive away from the return without a receipt.
Does Hertz Gold Plus Rewards change anything?
No. Hertz Gold (their loyalty tier) speeds up pickup but does not waive refueling charges or discount FPO. Car class upgrades and skip-the-counter are the only real Gold benefits.
What about President's Circle or Platinum?
Higher loyalty tiers (Five Star, President's Circle) offer more upgrades and priority, but fuel policies are unchanged. Refueling charges are calculated the same way for all customers regardless of status.
What happens if I return with more fuel than I picked up?
Hertz does not refund or credit the extra fuel. If you start at ¾ tank (they mis-noted it) and return at full, you've given Hertz free gas. This is why photographing the gauge at pickup matters - it lets you dispute if they later claim you received a full tank.
Renting an EV from Hertz?
Hertz's US refueling and recharging page says it aims to have EVs at about 80% charge at pickup, and that you never have to return an EV with more than 75% charge. If you do not buy the EV Purchase Option and do not return the car within 5% of the battery level at pickup, Hertz recharges it and bills the difference per kWh with a service fee included. The EV Purchase Option is priced similar to local charging stations per kWh plus a small convenience fee, and unused charge is not refunded. Third-party reporting (AutoSlash, April 2026) describes a $35 fee for returning with less charge than at pickup and an extra $25 below 10%; confirm the amounts on your rental agreement.
International Hertz rentals: what's different
Fuel is charged per liter, not per gallon, and rates vary significantly by country. In the UK, Germany, and Australia, the equivalent "return-full penalty" is often €3-€4 per liter - roughly $13-$17 per gallon equivalent. FillItRight auto-detects units and currency for international rentals.
Frequently asked questions
How much does Hertz charge for refueling?
Hertz does not publish a flat per-gallon refueling rate. If Hertz refuels the car, it charges for fuel at a local rate based on an average of local retail prices and may add a refueling service fee. Travelers report totals around $9.49 per gallon, roughly 2.6 times a $3.65 pump price, or about $71 on a 15-gallon tank returned half-empty. Check your rental agreement for the actual charge.
What is the Hertz Fuel Purchase Option (FPO)?
Hertz FPO lets you prepay for a full tank at pickup at a price Hertz describes as competitive with local pump prices. You can return the car at any fuel level with no refueling charge. Unused fuel is generally not refunded; Hertz says you are refunded for unused fuel only if you drove 75 miles or less. FPO saves money only if you return the tank nearly empty.
Does Hertz offer a same-price fuel guarantee?
Some Hertz locations offer FPO at or below local pump prices, but this varies by airport and region. Always check the exact per-gallon rate at pickup - at some airports FPO is more expensive than pump prices 3 miles away.
Does Hertz Gold Plus Rewards waive fuel charges?
No. Gold status does not waive refueling service charges or discount FPO. Fuel policies apply regardless of loyalty tier.
Can I dispute a Hertz refueling charge?
Yes, if you have evidence. Photograph the fuel gauge at pickup (proves your starting level) and keep your final gas station receipt (proves you filled up). Dispute in writing with Hertz within 30 days. If unresolved, file a credit card chargeback within 60 days.
What is Hertz's grace period for fuel levels?
There is no documented grace period. In practice, the refueling charge is triggered if the fuel gauge is noticeably below where it started at pickup. Gauge accuracy means a gallon or two of "slop" is often overlooked, but don't rely on it.
