As winter approaches, many of us are left wondering what to do with our lawn mowers. One of the most pressing questions is whether to leave oil in the lawn mower over the colder months. This decision can have a significant impact on the longevity and performance of your mower. In this article, we will delve into the world of lawn mower maintenance, exploring the pros and cons of leaving oil in your lawn mower over winter, and provide you with a clear understanding of what to do to keep your mower in top condition.
Understanding the Importance of Oil in Lawn Mowers
Before we dive into the specifics of winter storage, it’s essential to understand the role of oil in your lawn mower. Oil serves as a lubricant, reducing friction between moving parts and preventing overheating. It also helps to clean the engine, carrying away dirt and debris that could cause damage. A well-maintained oil system is critical to the overall health of your lawn mower, and neglecting it can lead to costly repairs or even render your mower unusable.
The Effects of Cold Weather on Lawn Mower Oil
Cold weather can have a significant impact on the oil in your lawn mower. As temperatures drop, the oil becomes thicker and more viscous, which can affect its ability to lubricate the engine. This can lead to increased wear and tear on the engine, as well as reduced performance. Additionally, condensation can form inside the engine, leading to rust and corrosion. This is especially true for lawn mowers that are stored in damp or humid environments.
Condensation and Rust: A Major Concern
Condensation is a significant concern when it comes to storing your lawn mower over winter. As the temperature fluctuates, moisture can gather inside the engine, leading to rust and corrosion. This can cause irreparable damage to your mower, resulting in costly repairs or even requiring a new engine. To mitigate this risk, it’s essential to take steps to prevent condensation from forming inside the engine.
The Pros and Cons of Leaving Oil in Your Lawn Mower Over Winter
Now that we’ve explored the importance of oil in your lawn mower and the effects of cold weather, let’s examine the pros and cons of leaving oil in your mower over winter.
Leaving oil in your lawn mower over winter can have both positive and negative consequences. On the one hand, leaving the oil in can help to keep the engine lubricated and prevent corrosion. This can be especially beneficial if you store your mower in a dry, climate-controlled environment. On the other hand, leaving old oil in the engine can lead to the formation of sludge and varnish, which can clog the engine and reduce performance.
The Risks of Old Oil: Sludge and Varnish
Old oil can break down over time, forming sludge and varnish that can clog the engine and reduce performance. This can lead to increased wear and tear on the engine, as well as reduced fuel efficiency. Additionally, old oil can become contaminated with dirt and debris, which can further exacerbate the problem.
A Cleaner Alternative: Draining the Oil
Draining the oil from your lawn mower before storing it over winter can help to prevent the formation of sludge and varnish. This can help to keep the engine clean and free of contaminants, reducing the risk of damage and improving performance. However, it’s essential to follow the correct procedure when draining the oil to avoid causing damage to the engine.
Best Practices for Storing Your Lawn Mower Over Winter

What happens if I leave oil in my lawn mower over winter?
Leaving oil in your lawn mower over winter can lead to several issues. For one, the oil can break down over time due to the cold temperatures, which can cause it to lose its lubricating properties. This can lead to increased wear and tear on the engine, resulting in costly repairs or even engine failure. Additionally, the oil can also become contaminated with condensation, which can cause it to become cloudy or develop a milky appearance. This can be a sign of moisture accumulation, which can lead to rust and corrosion within the engine.
It is essential to note that the type of oil used in your lawn mower can also play a role in determining whether it’s safe to leave it in over winter. Some oils are designed to withstand cold temperatures and can remain effective even after several months of storage. However, other oils may not be as resilient and can break down more quickly. To avoid any potential issues, it’s crucial to check your owner’s manual for specific guidance on storing your lawn mower over winter, as the manufacturer may have recommendations for the best course of action. By taking the time to properly prepare your lawn mower for winter storage, you can help ensure it remains in good working order and is ready to go when the new growing season begins.
How do I drain the oil from my lawn mower for winter storage?
Draining the oil from your lawn mower for winter storage is a relatively straightforward process. The first step is to consult your owner’s manual to determine the location of the oil drain plug, as this can vary depending on the make and model of your mower. Typically, the oil drain plug is located at the bottom of the engine, near the front of the mower. Once you’ve located the plug, you can use a socket wrench or ratchet to remove it, allowing the oil to drain out of the engine. Be sure to have a drip pan or container in place to catch the oil as it drains out, as you’ll need to dispose of it properly.
It’s also a good idea to replace the oil filter at the same time you drain the oil, as this can help ensure the engine remains clean and well-lubricated. After the oil has drained, you can replace the oil drain plug and tighten it securely to prevent any leaks. Finally, you can dispose of the used oil and filter responsibly by taking them to a recycling center or auto parts store that accepts used oil and filters. By taking the time to properly drain the oil from your lawn mower, you can help protect the engine and ensure it’s ready to go when the new growing season begins.
What type of oil should I use in my lawn mower during the winter months?
The type of oil you should use in your lawn mower during the winter months depends on the specific make and model of your mower, as well as the climate in which you live. In general, it’s best to use a high-quality oil that’s designed for use in small engines, such as those found in lawn mowers. These oils are typically formulated to provide excellent lubrication and protection in cold temperatures, which can help ensure your mower starts easily and runs smoothly. You can choose from a variety of oil types, including synthetic, synthetic blend, and conventional oil, each with its own unique characteristics and benefits.
When selecting an oil for your lawn mower, be sure to check the viscosity rating, which is typically indicated by a number such as 10W-30 or 5W-20. The viscosity rating refers to the oil’s thickness and flowability in cold temperatures, with lower viscosity oils flowing more easily and providing better cold-weather performance. For winter storage, it’s generally best to use a lower viscosity oil, such as 5W-20 or 0W-20, as this can help ensure your mower starts easily and runs smoothly even in cold temperatures. By choosing the right oil for your lawn mower, you can help protect the engine and ensure it’s ready to go when the new growing season begins.
Can I store my lawn mower with gas in the tank over winter?
Storing your lawn mower with gas in the tank over winter is generally not recommended, as this can cause several issues. For one, the gas can break down over time, which can lead to the formation of varnish and other deposits on the engine’s components. This can cause problems with the engine’s performance and can even lead to costly repairs. Additionally, the gas can also become stale, which can make it more difficult to start the engine when you’re ready to use it again. Furthermore, storing gas in the tank can also lead to condensation, which can cause rust and corrosion within the engine.
To avoid these issues, it’s best to drain the gas tank before storing your lawn mower over winter. You can do this by running the engine until it runs out of gas, or by using a gas siphon to remove the fuel from the tank. Be sure to dispose of the gas properly, as it can be hazardous to the environment. Alternatively, you can also use a fuel stabilizer to help preserve the gas and prevent it from breaking down over time. These products can help extend the life of the gas and keep it fresh for a longer period, making it easier to start the engine when you’re ready to use it again. By taking the time to properly prepare your lawn mower for winter storage, you can help ensure it remains in good working order and is ready to go when the new growing season begins.
