Hawaii has some of the highest fuel prices in the United States due to its isolated island geography and reliance on imported petroleum. Costco gas stations in Honolulu, Kapolei, and Kailua Kona offer significant savings — often 20 to 40 cents per gallon below local competitors. With 8 warehouses and 6 offering gasoline across Oahu, Maui, the Big Island, and Kauai, Costco membership is especially valuable for Hawaii residents looking to offset the state's premium fuel costs.
Each island has its own fuel market dynamics. Oahu, with the most Costco locations, tends to have the best pricing. Neighbor islands like Maui and the Big Island often see even higher prices due to additional shipping costs. Costco's Honolulu and Kapolei locations are particularly popular, with lines sometimes forming during peak hours. Since prices fluctuate daily, use our interactive map to find the nearest station.
Hawaii currently has 1 Costco location with diesel fuel. Diesel availability is limited across the islands, reflecting the smaller market for diesel passenger vehicles in Hawaii compared to mainland states. The single diesel-equipped Costco location serves commercial and personal diesel drivers who need high-quality ultra-low sulfur diesel at member-only prices.
For diesel drivers on islands without a Costco diesel station, Aloha Petroleum and Aloha Gas stations offer diesel at various locations. If you're weighing fuel options, our Costco diesel vs. Shell diesel comparison provides useful insights. Hawaii's tropical humidity makes diesel fuel more susceptible to water condensation in storage tanks, so consider using diesel fuel additives to protect your engine.
Costco gas stations in Hawaii typically operate from 6:00 AM to 10:00 PM on weekdays, with weekend hours generally 6:00 AM to 8:00 or 9:00 PM. The Honolulu and Kapolei locations can be especially busy during lunch hours and after work. A Costco membership is required to purchase fuel. Executive members earn 2% cashback on gas purchases (annual cap applies) — in Hawaii, where fuel prices are among the nation's highest, this cashback can offset a meaningful portion of membership cost.
