National Fuel Policy 2026: Refueling Fees Explained
National Car Rental's fuel policy is nearly identical to its sister brands Enterprise and Alamo (all owned by Enterprise Holdings). If you return below the starting level, National charges a price per gallon that its fuel FAQ says will be higher than local fuel prices. Travelers report about $10 to $11 per gallon, roughly 2.7 to 3 times a $3.65 pump price. This page walks through every National fuel option, the real math with 2026 prices, and how to always come out ahead.
National's fuel options
National's fuel FAQ lists these options. Check which one is on your rental agreement before you drive off:
| Option | What it means | Cost if not used perfectly |
|---|---|---|
| Return full (default) | Get the car full, return it full. You fuel up yourself. | Above local pump price, reported ~$10-$11/gal |
| Pay at time of rental (FSO) | Prepay for a full tank, estimated from current prices and the average tank size for your car class. Return it empty. | $1-$16 of unused fuel you paid for |
The math: each option with real numbers
A Chevrolet Equinox rental with a 15.6-gallon tank, returned half-empty, at a typical 2026 US gas price of $3.65/gallon. The $10.50 refueling figure is a typical reported rate, not a published National price:
3.9 gal of unused fuel lost = $13.85 wasted
Emerald Club, Executive, Executive Elite, Chairman's Circle
National's loyalty tiers offer real benefits - free day accrual, Emerald Aisle car choice for all Emerald Club members, and Executive Area access for Executive and Executive Elite members - but none of them waive refueling charges or discount prepaid fuel. Fuel charges are the same for members and non-members.
One subtle Emerald Club benefit relevant to fuel: faster return means less temptation to skip the fuel stop because you're running late. A rushed Emerald Aisle renter who returns at ¾ tank pays the same $50+ penalty as anyone else.
National vs Enterprise vs Alamo
Enterprise Holdings owns all three. Fuel policies are structurally identical, but:
- National is airport-focused and aimed at business travelers; its fuel FAQ says the per-gallon price on return will be higher than local fuel prices
- Enterprise has neighborhood and airport branches; it sells prepaid fuel at airport locations at the local price minus a per-gallon discount
- Alamo is positioned for leisure travel and uses the same two paid options as National (pay at time of rental, or pay upon return)
- None of the three publishes a nationwide per-gallon rate, so compare the rate on your agreement rather than assuming one brand is cheaper

How to avoid National's refueling fee
- Photograph the fuel gauge at pickup. Especially important with Emerald Aisle because you don't interact with a counter agent on pickup.
- Check your fuel option at booking and on your agreement. Make sure you have not prepaid for fuel you do not need.
- 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 in any dispute.
- Photograph the fuel gauge after filling with timestamp visible.
- Request a return receipt showing fuel level as full. Don't just drop keys in the box - that's when surprise charges happen.
Renting an EV from National?
National's fuel FAQ does not publish an electric vehicle charge-return rule or fee. Third-party reporting (AutoSlash, April 2026) says National charges a fee if you return an EV with less charge than when you rented it, without a published amount. Check your rental agreement for the required battery level and any recharge fee, and photograph the battery percentage at pickup and at return.
International National rentals
National operates primarily in North America, Central America, and the Caribbean. For international travel, the same Enterprise Holdings family operates Enterprise Rent-A-Car in Europe and Asia. Fuel is charged per liter in international markets, and refueling charges are often well above local pump prices. FillItRight auto-detects units and currency.
Frequently asked questions
How much does National charge for refueling?
National does not publish a fixed per-gallon refueling rate; its fuel FAQ says the price per gallon will be higher than local fuel prices. Travelers report about $10 to $11 per gallon, roughly 2.7 to 3 times a $3.65 pump price. On a 15-gallon tank returned half-empty, that is approximately $75 to $82. Check your rental agreement for the actual rate.
Does Emerald Club or Executive status waive fuel charges?
No. Emerald Club (free tier), Executive, Executive Elite, and Chairman's Circle offer Emerald Aisle car choice, Executive Area access at the Executive tiers, and free day accrual, but none waive refueling service charges or discount prepaid fuel.
What is National's Fuel Service Option?
National lets you pay for a full tank at the time of rental and return the tank empty, with no refueling charge. The upfront charge is an estimate based on current prices and the average tank size for your car class, and it may change at the time of rental. It is only cheaper than self-fill if you return the tank nearly empty.
Is National fuel policy the same as Enterprise and Alamo?
Nearly - National, Enterprise, and Alamo are all owned by Enterprise Holdings and share the same fuel structure: return at the level you received, prepay a tank, or pay a rate above local pump prices on return. None of the three publishes a nationwide per-gallon refueling rate, so compare the rate on your agreement rather than assuming one brand is cheaper.
Can I dispute a National 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.
Do Emerald Aisle cars come with a full tank?
National's fuel FAQ says rentals begin with a full tank. Emerald Aisle and the Executive Area just speed up vehicle choice; fuel level is independent. Photograph the gauge before driving off.
