Hawaii is a paradise in the Pacific that has breathtaking landscapes as well as a unique island culture. Yet, it’s no secret that living in this tropical paradise comes with a price tag, and that includes the cost of gasoline. Gasoline prices in Hawaii are consistently among the highest in the United States due to the state’s isolated location and dependence on imported oil. However, there are pockets of relief for those residents and visitors who seek out the best deals. In this article, we’ll explore the top six towns in Hawaii where you can find the cheapest gas and uncover the factors that influence these prices.

Pearl City, located on the island of Oahu, is part of the Honolulu metropolitan area. Sam’s Club, a membership-based retail store chain, has one of the lowest gasoline prices in the area.

Warehouse clubs like Sam’s Club can negotiate bulk purchasing deals with fuel suppliers, allowing them to offer lower prices to their members. While a membership fee is required, the potential savings on gasoline, as well as other purchases, can make it a worthwhile investment. Finally, lower gasoline prices can alleviate the financial burden on Pearl City’s residents, making everyday commuting and travel more affordable. If you’re ever on Oahu, make sure to stop by Sam’s Club to refuel.

Lower fuel prices at Costco can significantly benefit both residents and businesses in Iwilei, thus contributing to reduced transportation costs.

What Affects Gas Prices in Hawaii?

Gas prices in Hawaii are influenced by a combination of factors that are unique to the state due to its isolated location in the Pacific Ocean, its heavy reliance on imported oil, and the local market dynamics. Understanding these factors is crucial to grasp why gasoline prices in Hawaii are consistently higher than in many mainland states. Here are the key factors that affect gas prices in Hawaii:

Distance from Oil Sources

Hawaii is one of the most isolated landmasses on Earth, situated thousands of miles away from major oil production centers. The vast majority of the state’s oil is imported, primarily from Asia and the U.S. mainland. The sheer distance and transportation costs associated with shipping oil to Hawaii contribute significantly to the overall cost of gasoline.

Transportation Costs

Shipping and distribution costs account for a substantial portion of the gasoline price in Hawaii. The state relies on tanker ships to transport crude oil and refined gasoline to its ports. These costs are passed on to consumers at the pump.

Refining Costs

Hawaii has limited oil refining capacity, with just two refineries. This limited capacity means that the state must import a significant portion of its refined gasoline. As a result, Hawaii is often subject to price fluctuations in the global oil market, which can impact the cost of imported gasoline.


Hawaii has relatively high state taxes on gasoline. These taxes are used to fund transportation infrastructure and maintenance but can also add to the overall cost of fuel.

Market Competition

The number of gasoline retailers and the level of competition in a given area can influence prices. In Hawaii, where competition may be limited in some regions, prices can be higher due to less competitive pressure.

Tourism Demand

Hawaii’s tourism industry also significantly impacts gasoline prices. When tourism is booming, demand for gasoline rises, which can lead to higher prices.

Exchange Rates

As oil is traded globally in U.S. dollars, fluctuations in exchange rates between the U.S. dollar and other currencies can impact the cost of imported oil and, consequently, gasoline prices in Hawaii.

Environmental Regulations

Hawaii has stringent environmental regulations that require the use of cleaner-burning gasoline formulations. These formulations can be more expensive to produce, adding to the cost at the pump.

Supply Disruptions

Any disruptions in the supply chain, whether due to natural disasters, transportation interruptions, or other factors, can also lead to temporary spikes in gasoline prices in Hawaii.

Local Regulations

Finally, local regulations, zoning laws, and permit requirements can also impact the cost of gasoline retailing. These factors may vary from one Hawaiian county to another.

Despite these challenges, efforts are ongoing to reduce Hawaii’s dependence on imported oil and transition to cleaner and more sustainable energy sources. Initiatives include the development of renewable energy projects, the promotion of electric vehicles, and the improvement of public transportation systems.

Final Thoughts

While Hawaii’s gasoline prices are consistently among the highest in the United States due to the state’s geographical isolation and transportation costs, residents and visitors can find pockets of relief in towns like Pearl City, Waipio and Kahului. These towns benefit from various factors, including bulk buying power, membership-based pricing models, and military support. Thus, these lower gasoline prices not only ease the financial burden on residents but also help live a more affordable way of life in this tropical paradise.
