Handling ethanol-blended gasoline in your lawn mower before winter storage is crucial to ensure your equipment runs smoothly when spring arrives. Ethanol can attract moisture and cause engine problems if not managed properly. Here’s a comprehensive guide to help you prepare your lawn mower for winter storage.
What Is Ethanol-Blended Gasoline?
Ethanol-blended gasoline is a fuel mixture that includes ethanol, a renewable fuel made from corn and other plant materials. Common blends include E10 (10% ethanol) and E15 (15% ethanol). While ethanol helps reduce emissions, it can also attract moisture, leading to potential engine issues, especially in small engines like those in lawn mowers.
Why Is Ethanol a Concern for Lawn Mowers?
Ethanol can cause several problems in small engines:
- Moisture Attraction: Ethanol absorbs water, which can lead to phase separation and engine damage.
- Corrosion: Water and ethanol can cause corrosion in the fuel system.
- Fuel System Damage: Ethanol can degrade rubber and plastic components.
How to Prepare Your Lawn Mower for Winter Storage
1. Use a Fuel Stabilizer
Adding a fuel stabilizer to your gasoline can prevent ethanol-related issues. It helps keep the fuel fresh and prevents moisture attraction.
- Step-by-Step:
- Purchase a fuel stabilizer suitable for ethanol-blended gasoline.
- Add the recommended amount to your lawn mower’s fuel tank.
- Run the engine for a few minutes to circulate the stabilizer through the system.
2. Empty the Fuel Tank
If you prefer not to use a stabilizer, consider emptying the fuel tank entirely.
- Steps:
- Run the mower until it runs out of fuel.
- Alternatively, siphon out the remaining fuel and dispose of it properly.
3. Clean the Carburetor
Cleaning the carburetor ensures that no fuel residue remains, which could clog the system.
- Steps:
- Remove the carburetor bowl and clean it with carburetor cleaner.
- Check for any signs of wear or damage.
4. Inspect and Clean the Mower
Before storing your mower, give it a thorough cleaning and inspection.
- Checklist:
- Clean the mower deck to remove grass clippings.
- Check for any loose bolts or damaged parts.
- Sharpen or replace the mower blade if necessary.

How Often Should I Change Lawn Mower Oil?
Changing your lawn mower’s oil is essential for maintaining engine health. It’s recommended to change the oil every 50 hours of operation or at the start of each mowing season. Regular oil changes help remove dirt and debris that can damage the engine.
Can I Use E15 Gasoline in My Lawn Mower?
Most lawn mowers are designed for E10 gasoline. Using E15 can lead to engine damage due to higher ethanol content. Always check your mower’s manual for fuel recommendations to avoid voiding the warranty and causing potential harm.
What Happens if I Leave Gas in My Lawn Mower Over Winter?
Leaving gas in your lawn mower over winter can lead to several issues. Ethanol can attract moisture, causing phase separation. This can result in corrosion, clogged fuel systems, and starting problems in the spring. It’s best to either use a fuel stabilizer or empty the tank completely.
How Do I Know if My Lawn Mower Fuel Has Gone Bad?
Bad fuel often has a sour smell and a darker color. If your lawn mower struggles to start or runs poorly, old fuel might be the culprit. Draining and replacing the fuel with fresh gasoline is usually the best solution.
Are There Alternatives to Ethanol-Blended Gasoline?
Yes, you can use ethanol-free gasoline, often labeled as recreational fuel or ethanol-free fuel. It’s more expensive but eliminates the risks associated with ethanol. This fuel is ideal for small engines and seasonal equipment.
Summary
Properly handling ethanol-blended gasoline in your lawn mower before winter storage is vital for maintaining engine health. By using a fuel stabilizer, emptying the tank, and cleaning the carburetor, you can prevent ethanol-related issues. Regular maintenance and inspection will ensure your mower is ready to tackle the lawn come spring.
