Ultimate Guide to Storing Your Motorcycle with Ethanol-Blended Fuel: What Every Rider Needs to Know

When it comes to motorcycle storage, especially during the off-season or long periods of inactivity, there’s one important factor you can’t ignore: ethanol in your fuel. With most fuels containing up to 10% ethanol, it’s crucial to understand how ethanol affects your motorcycle’s engine and the steps you can take to protect it during storage.

In this comprehensive guide, we’ll cover the best practices for storing motorcycles when using ethanol-blended fuel, ensuring your bike remains in top shape while idle. Whether you’re storing it over the winter months or for an extended time, this guide will help you keep your motorcycle safe from the potential issues caused by ethanol.

The Impact of Ethanol in Fuel on Motorcycles

Ethanol is an alcohol-based additive found in many types of gasoline, often labeled as E10 (10% ethanol, 90% gasoline). While ethanol can help reduce emissions and boost fuel efficiency, it comes with a set of challenges for motorcycle owners, especially during long-term storage.

Here’s why ethanol can be problematic:

• Attracts Moisture: Ethanol is hygroscopic, meaning it absorbs moisture from the air. This can lead to water contamination in your fuel tank, causing corrosion in the fuel system.
• Fuel Separation: Ethanol-blended fuel can separate over time, creating a layer of water at the bottom of your tank and fuel system. This separation is known as phase separation and can lead to performance issues when you start your motorcycle again.
• Corrosion and Deposits: The moisture in ethanol-blended fuel can lead to corrosion in your fuel lines, carburetor, and fuel injectors. Ethanol can also leave behind gum-like deposits that clog the system.

How to Store Your Motorcycle with Ethanol-Blended Fuel

To avoid the potential issues ethanol can cause, follow these steps to properly store your motorcycle:

1. Add a Fuel Stabilizer

One of the most effective ways to prevent ethanol-related problems is by adding a fuel stabilizer. These additives are specifically designed to counteract the effects of ethanol, preventing moisture buildup and fuel separation.

• Tip: Add the fuel stabilizer to a full tank of gas. This prevents condensation in the tank and allows the stabilizer to mix evenly with the fuel.

2. Run the Engine After Adding Stabilizer

After adding the fuel stabilizer, start your motorcycle and let it run for a few minutes. This ensures the stabilized fuel circulates through the fuel system, including the carburetor or injectors.

• Why it matters: Running the engine helps the stabilizer reach all areas of the fuel system, reducing the risk of corrosion and gum deposits.

3. Fill Your Tank to the Top

Always store your motorcycle with a full tank of gas. This minimizes the amount of air in the tank and reduces the risk of moisture being absorbed by the ethanol.

• Pro Tip: A full tank also helps prevent internal rusting in the fuel tank.

4. Drain the Carburetor (If Applicable)

If your motorcycle is equipped with a carburetor, it’s a good idea to drain the fuel from it. This will prevent any leftover ethanol-blended fuel from gumming up and causing blockages.

• How to do it: Locate the drain screw on your carburetor and let the fuel drain into a container. This simple step can save you from costly repairs later.

5. Keep the Battery Charged

Although this tip isn’t directly related to ethanol, it’s vital for motorcycle storage. Use a battery tender to keep your motorcycle’s battery charged throughout the storage period. This will ensure that your bike starts smoothly when you’re ready to hit the road again.

• Bonus: A charged battery helps maintain the electrical system in good condition, which is crucial after long storage periods.

Why Ethanol-Free Gasoline Is a Better Option

While stabilizers can help mitigate the effects of ethanol, the best solution for long-term storage is to use ethanol-free gasoline whenever possible. Ethanol-free gas eliminates the risk of moisture absorption and phase separation, making it the best fuel choice for motorcycles in storage.

• Where to find it: Many gas stations offer ethanol-free fuel, particularly in rural or recreational areas. If you can’t find it, consider purchasing pre-mixed ethanol-free fuel specifically designed for small engines and motorcycles.

Quick Checklist for Storing a Motorcycle with Ethanol-Blended Fuel

• ✅ Add a fuel stabilizer to a full tank of gas
• ✅ Run the engine to distribute the stabilized fuel
• ✅ Fill the fuel tank completely to prevent moisture buildup
• ✅ Drain the carburetor to avoid gumming (if applicable)
• ✅ Keep the battery on a charger to maintain charge
• ✅ Consider ethanol-free gasoline for storage if available

The Long-Term Benefits of Proper Storage

Taking the time to properly store your motorcycle when using ethanol-blended fuel can save you from numerous headaches down the road. From avoiding costly repairs to ensuring optimal performance when you’re ready to ride again, these simple steps will protect your investment and prolong the life of your motorcycle.

• Improved Engine Health: By preventing ethanol-related issues, your engine will run more efficiently, giving you a smoother and more enjoyable ride.
• Saves You Money: A well-maintained motorcycle means fewer repairs and longer-lasting parts, saving you money in the long run.

Conclusion: Ethanol Fuel Storage Tips to Remember

Ethanol-blended fuel poses unique challenges when storing a motorcycle, but with the right approach, you can protect your bike and ensure it’s ready to go when you are. Remember to use a fuel stabilizer, fill the tank, and consider using ethanol-free gas for long-term storage.
