As winter approaches, you might wonder what to do with your lawn mower. Should you leave the gas in or drain it out? It’s a common question for homeowners who want to keep their equipment in top shape.
Not draining the gas can lead to issues like clogged fuel lines and a stubborn mower come spring. This article will guide you through the pros and cons of draining gas from your mower and help you make an informed decision. By the end, you’ll know exactly how to prepare your mower for the colder months, ensuring it starts up smoothly when you need it again.
Key Takeaways
- Fuel Quality Matters: Use fresh, high-quality gasoline to prevent engine issues like hard starting and misfiring, especially with ethanol-blended fuels.
- Draining Gas Reduces Risks: Draining gas before winter prevents fuel degradation and clogging, ensuring your mower starts smoothly in spring.
- Consider Fuel Stabilizers: If you decide not to drain the gas, adding a fuel stabilizer can prolong the life of gasoline and maintain fuel quality during storage.
- Essential Winter Maintenance: Clean the mower, change the oil, inspect the air filter, sharpen blades, and check the spark plug to ensure optimal performance come spring.
- Proper Storage Techniques: Store the mower in a cool, dry place with a breathable cover to protect it from dust and moisture, following manufacturer guidelines for best results.
Understanding Lawn Mower Fuel
Understanding lawn mower fuel helps you make informed decisions about winter storage. Proper fuel management can extend your mower’s lifespan and ensure optimal performance.
Types Of Fuel Used
Lawn mowers typically use two fuel types: gasoline and mixed fuel. Gasoline is standard for most mowers, while some models, like certain 2-stroke engines, require mixed fuel, which is a blend of gasoline and oil. Knowing what type your mower uses is crucial to maintaining its functionality.
Impact Of Fuel Quality
Fuel quality directly affects your mower’s performance. Fresh, high-quality gasoline prevents engine issues like hard starting and misfiring. Ethanol-blended fuels can absorb moisture over time, leading to fuel degradation. If you use ethanol fuel, consider using a fuel stabilizer. This additive helps maintain fuel quality during storage, reducing the risk of engine damage come spring.
Reasons To Drain Gas From Lawn Mower
Draining gas from your lawn mower before winter can save you a lot of trouble. Here are some key reasons why it’s advisable.

Preventing Fuel Degradation
Fuel can degrade over time, especially gasoline blended with ethanol. When left in the tank, gasoline can break down and form varnish, which clogs fuel lines and carburetors. By draining the gas, you eliminate the risk of degradation. Using a fuel stabilizer can also help maintain fuel quality if you decide to leave some fuel in. Stabilizers extend the life of gasoline, keeping it fresh until spring.
Avoiding Fuel System Issues
Clogged fuel systems can lead to poor performance or complete engine failure when you start your mower next season. Draining the gas reduces the likelihood of these issues. It prevents old fuel from gumming up the system and allows for smoother starts. Regular maintenance, along with draining gas, ensures your mower stays in good shape and ready to tackle your lawn as soon as the growing season begins.
Alternatives To Draining Gas
If you prefer not to drain gas from your lawn mower for winter, several alternatives can maintain your mower’s functionality.
Using Fuel Stabilizers
Using fuel stabilizers directly enhances fuel quality. Fuel stabilizers prevent gasoline from breaking down during storage, especially in ethanol-blended fuels. Add the recommended amount of stabilizer to the tank when filling up. Run the mower for about 10 minutes to ensure the stabilized fuel circulates through the system. This step helps keep the carburetor clean and reduces the risk of varnishing.
Storing Mower With Fuel
Storing your mower with fuel can be a practical option if you take certain precautions. Fill the tank completely with fresh gasoline to limit air exposure, which can lead to moisture accumulation. Add a fuel stabilizer to the gasoline to prolong its life during the winter months. Store the mower in a cool, dry place, protecting it from extreme temperatures. Always follow the manufacturer’s instructions for your specific mower model to ensure optimal results.

Preparing Your Lawn Mower For Storage
- Empty the Fuel Tank: Draining the gas prevents any degradation. Use a siphon or turkey baster to remove fuel from the tank. If you prefer not to drain, add a fuel stabilizer and run the mower to circulate it.
- Clean the Mower: Remove grass clippings, dirt, and debris from the deck and blades. Clean blades reduce rust and ensure effective cutting when you use the mower again.
- Change the Oil: Fresh oil keeps the engine lubricated and reduces wear. Change the oil according to your mower’s manual, usually after the last cut of the season.
- Inspect the Air Filter: A clean air filter enhances airflow. Check for blockages; replace the filter if it’s dirty or damaged. This small task boosts engine performance.
- Sharpen the Blades: Sharp blades cut cleanly, improving grass health. Sharpen blades before storing the mower to prepare for spring tasks. Use a sharpening stone or file, or consult a professional.
- Check Spark Plug: Inspect the spark plug for wear or damage. Clean or replace it as necessary. A new spark plug can improve starting efficiency.
- Battery Care: If you have a battery-operated mower, remove the battery for storage. Store it in a cool, dry place and periodically check its charge.
- Tires Maintenance: Inflate the tires to the recommended pressure. Properly inflated tires prevent flat spots and ensure smooth rolling when you bring the mower back out.
- Cover the Mower: Use a breathable cover to protect the mower from dust and moisture. Avoid using plastic covers, as they can trap humidity and lead to rust.
- Follow Manufacturer’s Instructions: Always refer to the owner’s manual for specific maintenance recommendations. Each mower has particular requirements that ensure longevity and performance.
Implementing these best practices preserves your mower’s condition through winter, making spring maintenance easier and more effective.
Conclusion
Taking the time to drain the gas from your lawn mower before winter can save you a lot of headaches come spring. It helps prevent fuel degradation and keeps your mower’s fuel system in top shape. If you choose to leave some gas in, using a fuel stabilizer is a smart move to maintain quality and avoid issues.
Remember that regular maintenance is key to ensuring your mower runs smoothly when you need it again. By following these winter prep tips, you’ll be ready to tackle your lawn with ease as soon as the warm weather returns. Happy mowing next season!
