About Gas Prices in Hawaii
Gas prices in Hawaii are reported daily by the U.S. Energy Information Administration (EIA) as part of their weekly survey of fuel retailers. The price shown is a statewide average for regular unleaded gasoline. Prices at individual stations in Hawaii may be higher or lower depending on location, brand, and local competition.
Several factors influence Hawaii's gas price: state fuel taxes, the distance from major refineries, pipeline and distribution infrastructure, and the required seasonal fuel blend.

Hawaii Fuel Taxes: ≈18.5¢/gal state + county tax
Hawaii has a low state-level gas tax, though county add-ons push the real total much higher. Hawaii's state fuel tax alone is about 18.5 cents per gallon, which looks low next to the national average. But every county — Honolulu, Maui, Hawaii, and Kauai — adds its own local fuel tax on top, and combined state-plus-county rates run well above the state figure alone. The state-level number understates what drivers actually pay in tax.
Tax figures are approximate state-level taxes and fees per gallon of regular gasoline and exclude the 18.4¢/gal federal excise tax. Rates change — verify current rates with the state's revenue or transportation department.
How Hawaii Gets Its Gasoline
Hawaii's isolation defines its fuel market. Par Hawaii's refinery in Kapolei, Oahu is the state's only refinery, importing crude oil by tanker from thousands of miles away since Hawaii has no crude production of its own. Every other island depends on gasoline shipped by barge from Oahu, adding another leg of transportation cost. That isolated, single-refinery supply chain is the main reason Hawaii consistently posts some of the highest pump prices in the country.
Where Gas Is Cheapest and Most Expensive in Hawaii
Oahu, closest to the Kapolei refinery, generally has the state's lowest prices. The Neighbor Islands — Maui, Kauai, and especially the Big Island — pay more because their gasoline arrives by inter-island barge on top of the ocean tanker trip crude oil already made to reach Hawaii.
