Alaska stands alone as the most challenging state for E85 flex fuel vehicle owners—zero public E85 stations exist anywhere in the state, including major cities like Anchorage, Fairbanks, and Juneau.
Extreme cold weather creates the primary barrier. E85 contains high concentrations of ethanol, which vaporizes poorly at low temperatures. Below -20°F—common during Alaska's winters—even winter-blend E85 causes extended cranking, rough idling, and potential no-start conditions. Geographic isolation compounds the problem—Alaska sits roughly 5,000 miles from Midwest ethanol production centers.
There are no public E85 stations in Alaska. Most gasoline sold in Alaska is already ethanol-free, actually preferred by many consumers for marine engines, small equipment, and cold-weather reliability.
The entire state lacks E85 infrastructure. This reality won't change in the foreseeable future due to climate and logistics challenges.
Simply use regular gasoline. Your flex fuel vehicle operates perfectly on conventional fuel—that's the "flex" advantage. If driving to Alaska from the lower 48 states, switch to regular gasoline before crossing into Canada's Yukon Territory.

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.
Alaska 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 Alaska 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 Alaska 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.
