Where to Find Ethanol-Free Gasoline?

Finding ethanol-free gasoline can be a quest, but it’s achievable. Primarily, you’ll discover it at marinas, small engine repair shops, and specific gas stations catering to classic car enthusiasts or owners of equipment sensitive to ethanol.

The Ethanol Problem: Why Seek Purity?

While ethanol is often touted as a renewable fuel additive that boosts octane and reduces carbon monoxide emissions, its corrosive nature and potential to damage older vehicles and small engines have spurred a demand for pure gasoline. Ethanol attracts water, leading to phase separation in fuel tanks, particularly during storage. This phase separation results in the ethanol and water mixture settling at the bottom of the tank, potentially causing engine damage and fuel system issues. Additionally, ethanol can corrode rubber and plastic components, especially in older vehicles and small equipment not designed for its use. For these reasons, many seek out ethanol-free gasoline for their boats, classic cars, motorcycles, lawnmowers, chainsaws, and other similar equipment.

Finding the Pure Stuff: Resources and Methods

The landscape of ethanol-free gasoline availability is constantly changing. Fortunately, several resources can help you pinpoint locations selling pure gasoline:

Online Resources:

Pure-Gas.org: This website is a comprehensive, user-updated database of gas stations across North America (primarily the United States and Canada) that sell ethanol-free gasoline. Users can search by zip code or state to find nearby locations.
Fuel-Testers: Some manufacturers of fuel testing kits maintain databases of ethanol-free gas stations. These are often less comprehensive than Pure-Gas.org but can provide additional leads.

Local Knowledge:

Marinas: As mentioned, marinas are often reliable sources of ethanol-free gasoline. Boat engines are particularly susceptible to ethanol damage due to extended periods of inactivity and exposure to moisture.
Small Engine Repair Shops: Shops specializing in lawnmowers, chainsaws, and other small engines frequently stock or know where to find ethanol-free gasoline.
Classic Car Clubs: Connect with local classic car clubs. Their members often share information about ethanol-free gasoline sources and even organize group purchases.
Airports: Some smaller, privately-owned airports offer aviation gasoline (Avgas) which is ethanol-free, but it’s crucial to verify its suitability for your engine before use. Avgas contains lead and is generally not compatible with catalytic converters.

Direct Inquiry:

Call Ahead: Always call the gas station or marina before driving there to confirm they currently have ethanol-free gasoline available. Inventory can fluctuate.
Ask the Locals: When traveling, ask residents or business owners for their recommendations on where to find ethanol-free gasoline.

Identifying Ethanol-Free Gasoline at the Pump

Even with online resources and local knowledge, it’s essential to verify the gasoline’s ethanol content at the pump. Look for these clues:

Signage:

Clear Labeling: Pay close attention to the pump’s labels. Stations selling ethanol-free gasoline will typically advertise it prominently with phrases like “Ethanol-Free,” “Pure Gasoline,” or “Zero-Ethanol.”
Octane Ratings: Ethanol-free gasoline is often offered in higher octane ratings, such as 91 or 93.

Pump Color Coding:

Specific Colors: Some gas station chains use specific colors to designate ethanol-free pumps. However, this is not universally consistent, so always rely on the signage first.

Verification:

Fuel Testing Kits: For absolute certainty, consider using a fuel testing kit designed to measure ethanol content. These kits are relatively inexpensive and can provide a definitive answer.

Ethanol-Free Gasoline: Considerations Beyond Availability

Finding ethanol-free gasoline is just one piece of the puzzle. Consider these additional factors:

Cost:

Premium Price: Ethanol-free gasoline typically costs significantly more than gasoline blended with ethanol. This is due to factors like lower production volume and specialized distribution.

Octane Rating:

Match Your Engine’s Needs: Ensure the octane rating of the ethanol-free gasoline meets your engine’s requirements. Using a higher octane than necessary won’t improve performance and is simply a waste of money.

Storage:

Fuel Stabilizers: Even ethanol-free gasoline can degrade over time, especially during storage. Use a fuel stabilizer designed for pure gasoline to prevent oxidation and gum formation.

Frequently Asked Questions (FAQs)

1. What exactly is ethanol and why is it added to gasoline?

Ethanol is an alcohol produced primarily from corn. It is added to gasoline to increase octane levels, reduce carbon monoxide emissions, and as a renewable fuel source.

2. What are the potential problems caused by ethanol in gasoline?

Ethanol can corrode rubber and plastic fuel system components, attract water leading to phase separation, reduce fuel efficiency, and damage small engines.

3. Is it safe to use ethanol-free gasoline in all vehicles?

Yes, it’s safe. In fact, older vehicles and small engines often perform better on ethanol-free gasoline. Modern vehicles designed to run on E10 (gasoline with up to 10% ethanol) can also use ethanol-free gasoline without any issues.

4. How can I tell if gasoline contains ethanol?

Look for labels at the pump indicating the ethanol content. If there’s no label, assume it contains up to 10% ethanol (E10). Fuel testing kits provide the most accurate determination.

5. What is phase separation and why is it a problem?

Phase separation occurs when ethanol absorbs water from the atmosphere, causing the ethanol and water mixture to separate from the gasoline and settle at the bottom of the fuel tank. This water-ethanol mixture can corrode the tank and damage the engine.

6. Is ethanol-free gasoline better for my lawnmower or chainsaw?

Yes. Small engines like those in lawnmowers and chainsaws are particularly vulnerable to ethanol damage. Ethanol-free gasoline will help prolong their lifespan and prevent costly repairs.

7. Can I store ethanol-blended gasoline for long periods?

It’s not recommended. Ethanol-blended gasoline is more prone to degradation and phase separation during long-term storage. If you must store it, use a fuel stabilizer specifically designed for ethanol-blended fuels. Ethanol-free gasoline, with the proper stabilizer, stores better.

8. Does the octane rating of ethanol-free gasoline differ from ethanol-blended gasoline?

The octane rating can vary. Ethanol itself acts as an octane booster. Ethanol-free gasoline often compensates for the lack of ethanol with higher-quality base gasoline, resulting in similar or higher octane ratings. Always match the octane rating to your engine’s requirements.

9. Are there any environmental benefits to using ethanol-free gasoline?

While ethanol is touted as a renewable fuel, its production can have environmental drawbacks, including land use and water consumption. Ethanol-free gasoline avoids these concerns. The environmental benefits are debatable and depend on the specific context of ethanol production.

10. Will using ethanol-free gasoline improve my fuel economy?

Potentially, yes. Ethanol has a lower energy content than gasoline. Switching to ethanol-free gasoline might result in a slight improvement in fuel economy, although the difference may not be significant.

11. Why is ethanol-free gasoline more expensive?

Ethanol-free gasoline is generally more expensive due to factors like lower production volume, specialized distribution channels, and the higher cost of the base gasoline used to achieve the desired octane rating. Demand for ethanol-free gasoline is also lower, leading to higher prices.

12. Is ethanol-free gasoline the same as aviation gasoline (Avgas)?

No. While both are ethanol-free, Avgas is specifically formulated for aircraft engines and typically contains lead. It is generally not suitable for use in cars or small engines with catalytic converters unless specifically designed for it. Always verify compatibility before use.
