E85 fuel is ethanol blended with gasoline, and finding stations that sell it requires a different search than regular gas

E85 is a fuel blend made of 85 percent ethanol and 15 percent gasoline. Not all gas stations carry it, and the ones that do are often clustered in certain regions or along specific highways. Unlike regular unleaded or diesel, E85 pumps are not at every corner station, so you need to know where to look and what to check before you drive there.

Your vehicle must be flex-fuel compatible to run on E85 safely. Most vehicles made after 2005 are not flex-fuel vehicles unless the manufacturer specifically built them that way. Check your owner's manual or look for a yellow gas cap or a badge on the back of your car that says "FFV" or "Flex Fuel Vehicle." If you are unsure, call your dealership with your vehicle identification number (VIN).

Key Takeaways

  • E85 is only sold at certain gas stations, and you must own a flex-fuel vehicle to use it safely.
  • The U.S. Department of Energy's Alternative Fuels Data Center is the most complete map of E85 stations nationwide.
  • E85 stations are most common in the Midwest and along major highways, and availability varies widely by region.
  • E85 typically costs less per gallon than regular gasoline, but your vehicle will use more fuel because ethanol has lower energy density.

Using the Department of Energy's Alternative Fuels Data Center

The U.S. Department of Energy runs the Alternative Fuels Data Center at afdc.energy.gov. This is the official government database of E85 stations across the country. Enter your address or zip code, select "Ethanol (E85)" as the fuel type, and the map will show you every station within your search radius that reports selling E85.

The map shows the station name, address, hours, and whether it is currently open or temporarily closed. Some stations update their status in real time; others update less frequently. Call ahead before driving a long distance, because a station listed as open may have run out of E85 or closed unexpectedly.

You can also filter by network — some stations belong to chains like Speedway, Casey's, or Pilot Flying J, which may have loyalty programs or payment apps. The data center also shows which stations have public charging for electric vehicles, in case that matters for your future plans.

Regional availability and why E85 is harder to find in some areas

E85 stations are concentrated in the Midwest, particularly in Iowa, Illinois, Minnesota, and Nebraska. This is because those states grow corn, which is processed into ethanol, and state policies often encourage E85 sales. You will find far fewer E85 pumps in the Northeast, Southeast, or West Coast, and some rural areas have none within 50 miles.

If you live in a region with few E85 stations, you may need to plan trips around fuel availability or stick with regular gasoline. Your flex-fuel vehicle can run on any blend of ethanol and gasoline — E85, E10 (10 percent ethanol, which is in most regular gas), or pure gasoline — so you are not locked into E85 even if you own an FFV.

Availability also changes seasonally. Some stations reduce E85 supply in winter because ethanol blends can be harder to start in cold weather, though modern vehicles handle this better than older ones.

Other ways to search for E85 stations

Google Maps and Apple Maps both show gas stations, but they often do not filter by fuel type or update E85 availability reliably. If you search "E85 near me," you may get results, but verify them with a phone call or the Department of Energy database before driving there.

Some fuel networks have their own apps. Speedway, Casey's, and Pilot Flying J all have mobile apps that show which of their locations carry E85. If you frequently use one chain, downloading their app can save time.

Ethanol producer websites and state energy offices sometimes maintain regional lists, but these are usually less complete than the federal database. Stick with the Department of Energy site as your primary source.

What to expect when you arrive at an E85 pump

E85 pumps are usually labeled clearly with a yellow or green label that says "E85" or "Ethanol." The pump handle may also be yellow. If you cannot find it, ask the attendant — some stations keep E85 in a separate area or require you to pay inside first.

E85 costs less per gallon than regular gasoline in most places, but your vehicle will travel fewer miles on a gallon of E85 because ethanol contains less energy than gasoline. You may use 20 to 30 percent more fuel overall, so the per-mile cost is often similar or slightly higher than regular gas. Check your fuel economy over a few fill-ups to see what you actually spend.

Pay the same way you would at any gas pump — credit card, debit card, or cash inside. Some stations require you to enter your zip code or pump number at the register before you can start pumping.

What to do if no E85 stations are near you

If the Department of Energy database shows no E85 within a reasonable distance, you have a few options. First, check again in a few months — new stations open regularly, especially in growing regions. Second, contact your state's energy office or environmental agency to ask about planned E85 infrastructure.

Third, use regular gasoline or a lower ethanol blend. Your flex-fuel vehicle runs safely on any ethanol blend up to E85, so you can use E10 (standard gas), E15, or E30 without any changes. You will not get the fuel cost savings of E85, but you will not have to drive out of your way either.

Some states offer tax credits or rebates for flex-fuel vehicles or for building E85 infrastructure. Check your state's environmental or energy website to see if you may have access to for any programs.

Frequently Asked Questions

Can I use E85 in a vehicle that is not flex-fuel compatible?

No. E85 will damage the fuel system, engine seals, and fuel injectors in a non-flex-fuel vehicle. Use only the fuel type your owner's manual specifies. If you are unsure whether your car is flex-fuel, call your dealership with your VIN rather than guessing.

Why is E85 cheaper than regular gas if I use more of it?

E85 is cheaper per gallon because ethanol is subsidized by the federal government and is cheaper to produce than gasoline. The per-gallon savings often outweigh the extra fuel consumption, but this varies by region and by current oil and corn prices. Track your own fuel costs over several fill-ups to see if E85 saves you money.

What happens if I accidentally put E85 in a regular car?

One fill-up usually will not cause when ready damage, but repeated use will corrode fuel system components. If you realize you made a mistake, do not panic — finish using that tank and switch back to regular gas. If you are concerned, have a mechanic inspect your fuel system.

Do I need to do anything special to maintain my flex-fuel vehicle?

No. Flex-fuel vehicles are designed to run on E85 without special maintenance. Use the oil and filter type your owner's manual recommends, and follow the same service schedule as any other car. E85 does not require different maintenance than regular gas.

Can I mix E85 with regular gas in my tank?

Yes, your flex-fuel vehicle can handle any blend of ethanol and gasoline. If you fill up with E85 and then add regular gas, or vice versa, the engine will adjust automatically. There is no harm in mixing them.
