Hawaii presents a unique challenge for flex fuel vehicle owners: no public E85 stations exist anywhere in the state. Despite an estimated 15,000+ registered FFVs, the extreme geographic isolation makes E85 economics virtually impossible.
Hawaii sits 2,400 miles from mainland ethanol production centers, and shipping costs across the Pacific make E85 prohibitively expensive. The Hawaii Clean Energy Initiative targets 100% clean energy by 2045, but state policy has shifted toward electric vehicles rather than liquid biofuels.
There are no E85 stations in Hawaii. While E85 is absent, biodiesel thrives—Pacific Biodiesel operates the nation's oldest continuously running biodiesel refinery on Maui.
All Hawaiian islands lack E85 infrastructure. This situation is unlikely to change given the state's electrification priorities.
Your flex fuel vehicle runs perfectly fine on regular gasoline—that's the only practical option here. If you're environmentally motivated, consider that Hawaii's electricity grid reached 79% renewable energy. When traveling to the mainland, California offers abundant E85 where you can take advantage of your FFV capabilities.

E85 is an ethanol-heavy fuel blend (51-83% ethanol) for flex fuel vehicles. Learn what E85 is, how it differs from regular gas, benefits, drawbacks, and if it's right for your car.
Find out if you can safely mix E85 and regular gasoline in your flex fuel vehicle, what happens if you accidentally use E85, and how FFVs handle mixed fuels.
Hawaii currently has no public E85 stations, so there's no in-state price comparison to make. If you own a flex fuel vehicle here, fill up on regular gasoline — your FFV runs on it without any modifications.
Only factory-certified flex fuel vehicles (FFVs) should run E85. Check your Hawaii vehicle for a yellow fuel cap, a "Flex Fuel" badge, an E85 sticker inside the fuel door, or confirm via the owner's manual or VIN decoder. Using E85 in a non-FFV can damage fuel lines, injectors, and seals — see our full FFV identification guide.
There are no verified public E85 stations in Hawaii today. If you're passing through with an FFV, plan to use regular gasoline — your vehicle handles it with no issues. Use the route planner to locate E85 in neighboring states.
