Ethanol-free gas is sold at specific station types, not everywhere

Ethanol-free gasoline is harder to find than regular fuel because most gas stations blend their fuel with 10 percent ethanol to meet federal requirements. You will not find it at most major chains like Shell, Chevron, or BP. Instead, look at marina fuel docks, farm co-ops, aviation fuel suppliers, and independent stations that cater to equipment owners. Some Costco locations and specialty fuel retailers also carry it, but availability changes by region and season.

The reason ethanol-free gas exists at all is that ethanol can damage certain engines — particularly older vehicles, small engines in lawn mowers and chainsaws, and marine engines. Boat owners and farmers have long needed this fuel, which is why it clusters around those industries. If you are looking for it, start by calling ahead rather than driving station to station, because stock runs out and not every location keeps it year-round.

Key Takeaways

  • Marina fuel docks and farm co-ops are your most reliable sources for ethanol-free gas because their customers depend on it for boats and equipment.
  • Call before you go, because ethanol-free pumps are not always stocked and availability varies by season and location.
  • Some independent gas stations and Costco locations carry ethanol-free fuel, but you will need to check with your local stations directly.
  • Expect to pay more for ethanol-free gas than regular fuel, and you may need to travel farther to find it.

Marina fuel docks as your first stop

Marinas sell ethanol-free fuel because boat engines are sensitive to ethanol, which absorbs water and can corrode fuel systems. Most marinas that have fuel pumps stock at least one grade of ethanol-free gasoline year-round. Call the marina directly and ask whether they sell fuel to the public or only to boat owners with slips. Some will pump fuel for anyone; others restrict it to members.

Marina fuel is often more expensive than station fuel because of overhead and because they assume you are already there for the boat. Prices also fluctuate with the wholesale market, just like regular gas. If you have a marina within a reasonable distance, this is usually your fastest option because staff know exactly what they have in stock and can tell you over the phone whether they are open and whether fuel is available that day.

Farm co-ops and agricultural suppliers

Farm co-ops and agricultural fuel suppliers carry ethanol-free gas because farmers use it in equipment that sits idle for months — ethanol fuel can gum up carburetors during storage. These locations are common in rural areas and often have large fuel tanks. Some are open to the public; others sell only to members or to people with agricultural operations.

Call ahead to confirm they sell retail fuel and whether membership is required. If you live near farmland, a quick search for "farm co-op fuel" or "agricultural fuel supplier" plus your county name will show you what is nearby. These suppliers often have better prices than marinas because they operate on thinner margins and move more volume.

Aviation fuel suppliers and small airports

Small airports and aviation fuel suppliers stock ethanol-free fuel because aircraft engines require it. Some public-use airports sell fuel to anyone with a vehicle, though this is less common than marina or farm co-op sales. Call the airport's fuel desk or fixed-base operator (FBO) and ask whether they pump automotive fuel or only aviation fuel, and whether they sell to non-pilots.

This option works best if you live near a small regional airport rather than a major commercial hub. Availability is hit-or-miss, and prices can be higher because aviation fuel has stricter quality standards. However, if you are in an area with several small airports, one of them may have a fuel desk that serves the public.

Independent gas stations and specialty retailers

Some independent gas stations — not chains — stock ethanol-free fuel, particularly in areas with older vehicles, classic car communities, or high concentrations of small-engine equipment. These stations are scattered and do not advertise widely, so finding them requires local knowledge or phone calls. Search online for "ethanol-free gas near me" or "non-ethanol fuel" and call the results to confirm they actually carry it.

Specialty fuel retailers that focus on vintage cars, motorcycles, or equipment maintenance sometimes stock ethanol-free gasoline. These businesses are rare but worth checking if you have them in your area. Prices vary widely depending on the retailer's overhead and local demand.

Costco and warehouse clubs

Some Costco locations carry ethanol-free fuel at their gas stations, but not all do. Availability depends on the regional warehouse and whether there is enough local demand. You will need a Costco membership to buy fuel. Call your local Costco gas station directly to ask whether they stock ethanol-free gasoline and what grades they offer.

If your Costco does carry it, prices are typically competitive because Costco operates on low margins. However, do not assume your location has it — you must confirm by phone or by visiting the pump.

Online tools and apps for locating ethanol-free fuel

Several websites and apps track ethanol-free gas stations, though coverage is incomplete because the fuel is not sold everywhere. GasBuddy has a filter for ethanol-free fuel, though not all stations update their inventory regularly. Pure Gas (puregas.org) is a community-maintained database specifically for ethanol-free stations and is often more current than general gas apps, though it depends on users reporting their local stations.

These tools are useful for finding candidates in your area, but always call ahead to confirm the station has fuel in stock that day. Inventory changes frequently, especially at smaller retailers, and you do not want to drive across town only to find the pump is empty or closed.

Frequently Asked Questions

How much more does ethanol-free gas cost?

Prices vary by location and retailer, but ethanol-free fuel typically costs 10 to 50 cents more per gallon than regular fuel. Marina fuel tends to be on the higher end because of overhead. Farm co-ops and independent stations are often cheaper. Prices also shift with the wholesale market, so there is no fixed markup.

Can I use ethanol-free gas in a regular car?

Yes, ethanol-free fuel works in any gasoline engine. It will not harm a modern car designed to run on ethanol-blended fuel. You might use it if you want to store a vehicle for the winter or if you prefer it for other reasons, but it is not necessary for most cars built in the last 20 years.

What if there are no ethanol-free stations near me?

If you cannot find ethanol-free fuel locally, you have a few options: drive to the nearest marina or farm co-op even if it is farther away, use fuel stabilizer in regular gas if you are storing equipment, or check whether your equipment actually requires ethanol-free fuel — many modern small engines can run on regular gas without problems.

Do I need to tell the pump attendant I want ethanol-free fuel?

At marinas and farm co-ops, yes — tell the attendant which grade you want and they will direct you to the right pump. At stations with multiple fuel types, ethanol-free pumps are usually labeled clearly. If you are unsure, ask before you start pumping.

Is ethanol-free fuel better for my engine?

It depends on your engine. Ethanol-free fuel is better for older vehicles, small engines, and marine engines because ethanol can corrode fuel systems and absorb water. Modern cars are designed to run on ethanol-blended fuel and do not benefit from ethanol-free gas. Check your owner's manual or equipment documentation to see what your engine requires.
