Short answer: Closest: the 24-hour Shell at 3269 Koapaka Street, two blocks from the rental return. Cheaper: Texaco on Valkenburgh Street or, with a membership, Costco in Iwilei.
Skipping the pre-return fill-up at HNL costs more than almost anywhere else on Oahu. Here is where to actually stop.
The closest option
The closest gas station to Honolulu Airport for a rental return is the Shell at 3269 Koapaka Street, about two blocks from the CONRAC rental return facility. It is listed as open 24 hours at (808) 839-7616, and it operates as an Aloha Island Mart. Yelp puts it about 0.6 miles from Terminal 1. That makes it the most convenient stop if you’re already close to drop-off time. Shell’s station page has the details.
Other nearby options
The Nimitz Highway and Aolele Street corridor, within about a 5-minute drive of the airport, has several more choices including Shell, 76, and Aloha Petroleum, useful if the Koapaka Street station has a line. The 76 at 2140 N Nimitz Highway is also listed as open 24 hours, at (808) 848-0480.
Is the closest station the cheapest?
Not necessarily. On October 5, 2026, Google’s station listings showed regular at $5.80 at the Koapaka Street Shell and $5.66 at the 76 on North Nimitz. That is a 14-cent difference, about $2 on a 14-gallon tank, so the closer station costs a little more but saves a detour. Prices change daily, so treat this as a snapshot and check the price on the map before you commit.
Cheapest gas near the airport
The closest pump is rarely the cheapest. Here is how the options compared on Google’s station listings on October 14, 2026 (regular unleaded):
| Station | Address | Regular | Best for |
|---|---|---|---|
| Shell (Aloha Island Mart) | 3269 Koapaka St | $5.80 | Closest to the rental return, open 24 hours |
| 76 | 2140 N Nimitz Hwy | $5.66 | On the way in along Nimitz, open 24 hours |
| Texaco | 986 Valkenburgh St | $5.54 | Cheapest of the three, open 24 hours |
| Costco Gas (Iwilei) | 525 Alakawa St | Members only | Coming from Waikiki or downtown and you have a Costco card |
The Costco station is about 4 miles from the airport, so it only makes sense if it is already on your route from Waikiki or downtown, and it needs a membership card at the pump. Prices move daily, so check the map before you commit.
Budget real time for this
Plan for 45 to 60 minutes total between fueling up, driving to the CONRAC, completing the return inspection, and taking the shuttle to your terminal. Most rental agreements charge a refueling fee well above pump prices if you return with less than a full tank. It is rarely close.
- Pumps can back up right before peak departure banks: don’t cut this as close as you would at a quiet neighborhood station.
- The CONRAC return address is 300 Rodgers Blvd: use that for GPS, not a generic airport pin.
- This is separate from the general airport terminal drop-off loop used for non-rental passenger drop-offs.
Picking up instead of returning? The Honolulu Airport rental car guide covers that side of the trip.
Official ground transportation details for the CONRAC facility (shuttle stops, terminal walk, facility layout) are maintained by the state at the Hawaii Airports System’s official HNL ground transportation page, worth a check if anything above has changed since this was last verified.
