Why Hawaii Gas Costs More

Every drop arrives by tanker

Hawaii has no in-state oil production. Crude and finished fuel are shipped from refineries on the U.S. mainland and overseas. The freight cost shows up at the pump — usually 60 to 90 cents per gallon above the West Coast average.

One refinery does most of the work

Par Hawaiʻi's Kapolei refinery on Oʻahu produces the bulk of the state's gasoline. With limited domestic refining capacity, supply disruptions hit harder than they would on the mainland.

State and county taxes stack up

Hawaiʻi's combined state, county, and federal fuel taxes are among the highest in the country. The exact amount varies by county — Maui and Kauaʻi typically run a few cents higher than Oʻahu.

Smaller markets, less competition

Each neighbor island has fewer stations and fewer wholesale suppliers than Oʻahu. That's why a Big Island or Maui pump price often runs 15 to 30 cents above what you'd pay in Honolulu on the same day.

How to Save at the Pump

Costco is the cheapest option on every island

Costco has gas stations in Honolulu, Kapolei, and Hawaiʻi Kai on Oʻahu, plus Kahului on Maui, Kona on the Big Island, and Lihuʻe on Kauaʻi. Members typically save 30 to 60 cents per gallon vs. the island average. Bring your card — it's enforced at the pump.

Avoid Waikīkī, airport, and resort-area stations

The Shell on Kūhiō Avenue, the Chevron near OGG, and any resort-corridor station charge a tourist premium — sometimes 50 cents above what a local station two miles away charges. Fill up before you reach the airport on the way back.

Use GasBuddy or Waze to find the cheapest pump nearby

Both apps show real-time station-level pricing across all four islands. Useful when you have flexibility on the route — saving 20 cents a gallon on a 40-gallon week of driving adds up to real money over a long trip.

Pick a fuel-efficient rental — and use the right grade

A Toyota Corolla rents for about the same as a mid-size SUV but burns half the gas. Stick to Regular unless your rental's manual specifically requires Premium — most do not, despite what the upsell at the counter implied. Compare rates at Discount Hawaii Car Rental for the lowest published price across all major brands.

Don't pay for Premium "for the car's sake"

Most modern gasoline engines — including every standard rental — are tuned for 87 octane. Premium burns money, not better. Read the inside of the fuel cap if you're not sure; the manufacturer's required grade is printed there.

Plan one big fill, not five small ones

Rental cars are typically returned with a full tank. Topping off at $1 here and $3 there ratchets up your total per-gallon cost because each small purchase takes the pump's minimum price-rounding hit. One big fill the morning of return saves a few dollars and a lot of stops.

About This Data

Where do these prices come from?

Numbers are pulled directly from AAA's daily Fuel Gauge Report for Hawaii. AAA collects retail credit-card transaction data from over 100,000 gas stations nationwide via OPIS (Oil Price Information Service). The state and county averages reflect actual prices paid yesterday, refreshed every morning.

How often does this page update?

Once a day, around 4 AM HST. A small Cloudflare Worker scrapes the AAA Hawaii page, compares to the previous day's reading, and only commits a change if a price actually moved. If AAA is slow or briefly unreachable, you'll see the most recent good reading rather than a broken page.

Why is the AAA county average different from what I'm seeing at a specific station?

AAA reports an average across hundreds of stations on each island. Individual stations vary by 30 to 80 cents per gallon depending on neighborhood, brand, and proximity to tourist areas. The AAA average is the right number for trip budgeting; for the cheapest specific pump, use GasBuddy or Waze.

What about Molokaʻi and Lānaʻi?

AAA folds both into the Maui County reading. Real prices on Molokaʻi and Lānaʻi typically run 30 to 60 cents above the Maui County average because of even smaller markets and less competition. Lānaʻi has a single gas station; Molokaʻi has a handful clustered in Kaunakakai.

How accurate is "yesterday" data for "today's" trip planning?

Hawaiʻi gas prices move slowly compared to the mainland — large day-to-day swings are rare outside of supply shocks. The previous day's average is a reliable estimate for budgeting today's rental car or road trip.

Hawaiʻi Weather Forecast

Today’s Weather Brief · AI-voiced · ~45s

Updated

Read the transcript

Partly cloudy on the windward side, mostly sunny on the leeward side. Trade winds are strong and will stay that way through Wednesday, bringing passing showers to windward slopes.

Surf builds this weekend—a south swell is coming in and could reach warning levels on south-facing beaches by Saturday and Sunday. Winds ease late Thursday, and you'll see more organized showers Friday through Saturday as a system moves nearby. Small Craft Advisory is up through Wednesday evening, so water's rough if you're thinking about boats.

Stick to leeward beaches and the sunny side through Wednesday. Save your snorkeling for after the weekend swell passes.
