Dollar Fuel Policy 2026: Refueling Fees Explained

Updated April 2026 Β· 6 min read

Dollar is owned by The Hertz Corporation alongside Hertz and Thrifty. Like its sister brands, Dollar uses the standard return-full default and offers a Fuel Purchase Option, but typically charges $8.50 to $9.50 per gallon for refueling β€” slightly less than Hertz, on par with Thrifty. Dollar is positioned for budget-conscious travelers, but the fuel math is the same.

Dollar's fuel options

Dollar presents these fuel options at the counter, sometimes pre-selected during online booking:

OptionWhat it meansCost 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 Kia Forte rental with a 13.2-gallon tank, returned half-empty, at a typical 2026 US gas price of $3.65/gallon:

Scenario A: Return-full, self-fill
6.6 gallons Γ— $3.65/gal = $24.09 at your gas station of choice
Total fuel cost: $24.09 βœ“ cheapest
Scenario B: Return-full, but only half-full
6.6 gallons Γ— $9.00/gal = $59.40 Dollar refueling service charge
Total fuel cost: $59.40 βœ— $35.31 penalty
Scenario C: FPO, return at ΒΌ tank
13.2 gal prepaid Γ— ~$3.55/gal = $46.86 at pickup
3.30 gal of unused fuel lost = $11.71 wasted
Total fuel cost: $46.86 βœ— $22.77 more than self-fill
Bottom line: Self-fill is cheapest in 85%+ of Dollar rentals. FPO only wins if you're confident you'll return the car nearly empty. The refueling service charge is the worst case β€” avoid it by filling up before you reach the return lot.

Dollar vs. Hertz vs. Thrifty: same parent, similar policies

Dollar, Hertz, and Thrifty are all Hertz Corporation brands. Dollar and Thrifty share nearly identical fuel pricing (~$9/gal refueling), both about $0.50 cheaper than Hertz at the same airport. The Express loyalty program does not affect fuel pricing.

How to avoid Dollar's refueling fee

  1. Photograph the fuel gauge at pickup. Critical proof of starting fuel level.
  2. Decline FPO unless your situation specifically requires it (very short rental, returning empty).
  3. Find a gas station 3-5 miles from the return location. Airport-adjacent stations charge 20-50Β’ more per gallon.
  4. Keep the gas receipt β€” required evidence in any dispute.
  5. Photograph the fuel gauge after filling, with timestamp.
  6. Wait for a return receipt that shows fuel level as full before leaving the lot.

Frequently asked questions

Approximately $8.50 to $9.50 per gallon. Rate varies slightly by location. Roughly 3 to 4 times retail pump price. On a 13.2-gallon tank returned half-empty, that's approximately $56-$63 in charges.

FPO lets you prepay for one full tank at pickup at near-retail prices. No refueling charge regardless of return level, but no refund for unused fuel.

Does Dollar Express affect fuel charges?

No. Dollar Express loyalty does not waive refueling service charges or discount the Fuel Purchase Option (FPO).

Can I dispute a Dollar 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 Dollar?

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.

Do Dollar's fuel rates differ at airport vs. off-airport locations?

Yes β€” airport locations typically charge $0.50 to $1.00 more per gallon for refueling than off-airport branches. The fuel policy structure is identical, just the per-gallon rate varies.
