Thrifty Fuel Policy 2026: Refueling Fees Explained

Q: How much does Thrifty charge for refueling?

Thrifty typically charges $8.50 to $9.50 per gallon to refuel a rental returned below the starting fuel level. This is roughly three to four times the retail pump price. On a 10.8-gallon tank returned half-empty, that is approximately $46 to $51 in refueling charges.

Q: What is the Thrifty Fuel Purchase Option (FPO)?

The Fuel Purchase Option (FPO) (FPO) lets you prepay for one full tank at pickup at a rate typically just below the local retail pump price. You can return the car at any fuel level with no refueling charge, but you do not receive a refund for unused fuel. FPO is only cheaper than self-fill if you return the tank nearly empty.

Q: Does Thrifty Blue Chip waive fuel charges?

No. Thrifty Blue Chip loyalty membership does not waive refueling service charges or discount the Fuel Purchase Option (FPO). Fuel policies apply regardless of loyalty tier.

Q: Can I dispute a Thrifty refueling charge?

Yes. 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 Thrifty within 30 days. If unresolved, file a credit card chargeback within 60 days.

Thrifty is owned by The Hertz Corporation alongside Hertz and Dollar. Its fuel policies are structurally identical to Hertz — same return-full default, same FPO option — but the per-gallon refueling rate is typically $0.50 to $1 cheaper than Hertz at the same airport. That makes Thrifty the cheapest of the Hertz brands if you accidentally return below full.

Thrifty's fuel options

Thrifty presents these fuel 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.	$8.50-$9.50/gal refueling charge if below full
Fuel Purchase Option (FPO)	Prepay for one full tank at pickup at near-retail rates.	$1-$16 of unused fuel you paid for
Flat refueling fee (select locations)	Flat $15-$25 fee regardless of return level.	Cheapest only on <40 mile rentals

The math: real-world numbers

A Nissan Versa rental with a 10.8-gallon tank, returned half-empty, at a typical 2026 US gas price of $3.65/gallon:

Scenario A: Return-full, self-fill

5.4 gallons × $3.65/gal = $19.71 at your gas station of choice

Total fuel cost: $19.71 ✓ cheapest

Scenario B: Return-full, but only half-full

5.4 gallons × $9.00/gal = $48.60 Thrifty refueling service charge

Total fuel cost: $48.60 ✗ $28.89 penalty

Scenario C: FPO, return at ¼ tank

10.8 gal prepaid × ~$3.55/gal = $38.34 at pickup
2.70 gal of unused fuel lost = $9.59 wasted

Total fuel cost: $38.34 ✗ $18.63 more than self-fill

Bottom line: Self-fill is cheapest in 85%+ of Thrifty rentals. FPO only wins if you're confident you'll return the car nearly empty. The refueling service charge is the worst case — avoid it by filling up before you reach the return lot.
