The crisp air has arrived, the leaves are changing colors, and the smell of pumpkin spice fills the air. As the days grow shorter and colder, you know what that means: it’s time to put your lawn mower away for the winter. But before you tuck it into the garage, a crucial question arises: should you drain the gas? This seemingly simple decision can have a significant impact on your mower’s health and your wallet.
In short, draining the gas from your lawn mower for winter is highly recommended. While it may seem like an extra step, it can prevent a range of problems and ensure your mower is ready to go when spring rolls around. This article will delve into the reasons why draining the gas is beneficial, explore alternative options, and equip you with the knowledge to make the best decision for your lawn mower.
The Benefits of Draining Gas for Winter Storage
Leaving gas in your lawn mower over the winter months can lead to a host of issues. Here’s why draining the gas is a smart move:
1. Preventing Fuel Degradation and Gum Formation
Gasoline is a volatile substance that deteriorates over time, especially in the presence of heat and sunlight. As it ages, it breaks down into harmful byproducts like varnish and gum. These substances can clog fuel lines, carburetor jets, and other critical engine components. Even if your mower starts in the spring, it might run poorly or even fail altogether due to clogged fuel lines.
2. Avoiding Engine Damage
Fuel degradation can also lead to engine damage. When varnish and gum build up, they can stick to moving parts within the engine, causing friction and wear. This can lead to decreased performance, increased fuel consumption, and even permanent damage to the engine.
3. Eliminating Fire Hazards
Old gas can become highly flammable, increasing the risk of fire in your storage area. By draining the gas, you remove this potential hazard and ensure a safe environment for your lawn mower.
Alternatives to Draining Gas: Fuel Stabilizers
While draining the gas is the most effective way to prevent issues, you can also consider using a fuel stabilizer. These additives are designed to slow down the degradation process and help preserve the quality of gasoline. However, fuel stabilizers are not a perfect solution and should be used in conjunction with other storage practices.
1. Advantages of Fuel Stabilizers:
- Convenience: Fuel stabilizers are readily available at most hardware and automotive stores.
- Extended Storage: They can help prevent fuel degradation for longer periods than regular gasoline.
2. Disadvantages of Fuel Stabilizers:
- Not a Complete Solution: They do not fully eliminate the risk of fuel degradation and gum formation.
- Limited Effectiveness: Their effectiveness depends on the quality of the stabilizer, the type of fuel, and the storage conditions.
How to Properly Drain the Gas From Your Lawn Mower
Draining the gas is a relatively simple process, but it’s important to do it correctly to avoid spills or contamination.
1. Safety First!
- Always work in a well-ventilated area away from any open flames or sparks.
- Wear protective gloves and eye protection to avoid contact with gasoline.
2. Preparing for the Drain
- Turn off the fuel valve (if equipped) and let the engine run until it stalls. This will help ensure all the fuel is drained from the carburetor and fuel lines.
- If your mower has a primer bulb, press it several times to help draw any remaining fuel out.
3. Draining the Tank
- Use a siphon pump or a fuel-safe container to drain the gas from the tank.
- Dispose of the old gas properly according to local regulations. Never pour it down the drain or into the ground.
4. Running the Engine Dry
- Once the tank is drained, start the engine and let it run until it stalls. This will help ensure any remaining fuel in the carburetor and lines is consumed.
Maintaining Your Lawn Mower for Winter Storage
Draining the gas is a crucial step in preparing your lawn mower for winter, but it’s not the only thing you need to do. Here are some additional steps for proper winter storage:
1. Cleaning and Maintenance
- Clean your mower thoroughly, removing any grass clippings, dirt, or debris.
- Check the spark plug, air filter, and blade for wear or damage.
- Consider changing the oil if necessary.
2. Storage Conditions
- Store your mower in a dry, well-ventilated area, preferably indoors.
- Avoid storing it on a concrete floor, as this can promote condensation.
- Cover the mower with a breathable cover to protect it from dust and moisture.
Conclusion: The Choice is Yours
Ultimately, the decision of whether to drain the gas from your lawn mower for winter comes down to your personal preferences and storage conditions. If you have a reliable storage space and can commit to a thorough draining process, it’s the best way to ensure your mower is ready for spring. However, if you prefer a more convenient solution, a fuel stabilizer might be a suitable alternative. By taking the time to prepare your mower properly, you can avoid potential problems and extend its lifespan.
FAQs
Should I Drain the Gas From My Lawn Mower for Winter?
Yes, it is recommended to drain the gas from your lawn mower for winter storage. Gasoline can degrade over time, especially when exposed to the elements. This can lead to gumming and varnish buildup in your engine, which can cause starting problems and damage your mower in the long run. By draining the gas, you help prevent these issues and ensure a smooth start next spring.
What Happens if I Don’t Drain the Gas?
If you leave gasoline in your lawn mower over winter, it will start to degrade. This degradation process creates harmful deposits that can clog the carburetor and fuel lines. These deposits make it harder for your mower to start, and they can eventually lead to engine damage requiring costly repairs.
How Do I Drain the Gas From My Lawn Mower?
Draining the gas is a simple process. First, ensure your mower is cool and in a well-ventilated area. Then, locate the gas tank cap and carefully remove it. Next, use a siphon pump to draw the gasoline out of the tank and into a suitable container. You can also tip the mower and drain the gas through the tank’s outlet. Be careful to avoid spills.
What Should I Do With the Drained Gas?
Once you’ve drained the gasoline, properly dispose of it. Never pour it down the drain or into the soil, as it is harmful to the environment. Instead, take it to a local recycling center or gas station that accepts used gasoline.
Can I Add a Fuel Stabilizer Instead of Draining the Gas?
Yes, adding a fuel stabilizer to your gas tank can help prevent degradation and extend the lifespan of the fuel. However, it is not a substitute for draining the gas entirely. Fuel stabilizers work best when used with fresh gas and are not as effective for gasoline that has already begun to degrade.
Should I Also Drain the Oil?
It’s a good idea to drain the oil from your mower before storing it for winter. Old oil can thicken and become acidic, leading to engine corrosion and damage. Changing the oil ensures your mower is ready for the next season.
How Often Should I Drain the Gas?
It’s recommended to drain the gas from your lawn mower at least once a year, particularly before storing it for winter. However, if you only use your mower for a short season, you might consider draining the gas after each use, especially if you know you won’t be using it for several weeks.
