As the summer months approach, many of us are eager to get our lawn mowers out and start maintaining our yards. However, with the excitement of warmer weather and outdoor activities, it’s easy to forget about the small details, such as storing our lawn mowers properly. One common mistake many people make is leaving gas in their lawn mowers for extended periods, which can lead to a range of problems. In this article, we will explore the potential issues caused by leaving gas in your lawn mower and provide you with a step-by-step guide on how to address the problem.
Understanding the Risks of Leaving Gas in Your Lawn Mower
Leaving gas in your lawn mower can cause several problems, including stale fuel, clogged carburetors, and damage to the engine. Gasoline is a volatile liquid that can break down over time, leading to the formation of gum, varnish, and other deposits. These deposits can clog the fuel system, including the carburetor, fuel injectors, and fuel lines, causing poor engine performance, decreased power, and increased emissions. Additionally, stale fuel can also lead to the growth of bacteria and mold, which can further contaminate the fuel system.
The Effects of Stale Fuel on Your Lawn Mower
Stale fuel can have severe consequences on your lawn mower’s engine and overall performance. Some of the effects of stale fuel include:
- Reduced engine power: Stale fuel can cause the engine to run rough, leading to reduced power and decreased performance.
- Increased emissions: Stale fuel can cause the engine to produce more emissions, contributing to air pollution and environmental damage.
- Clogged fuel system: The deposits formed by stale fuel can clog the fuel system, including the carburetor, fuel injectors, and fuel lines, leading to poor engine performance and increased maintenance costs.
- Corrosion and damage: Stale fuel can also cause corrosion and damage to the engine and fuel system components, leading to costly repairs and replacements.
How to Identify Stale Fuel in Your Lawn Mower
Identifying stale fuel in your lawn mower can be challenging, but there are some signs to look out for. Some common indicators of stale fuel include:
* Discolored fuel: Stale fuel can cause the fuel to become discolored, turning a darker brown or yellowish color.
* Unpleasant odors: Stale fuel can produce unpleasant odors, such as a sour or acidic smell.
* Sludge or sediment: Stale fuel can cause the formation of sludge or sediment at the bottom of the fuel tank.
Draining and Disposing of Old Gas
If you’ve left gas in your lawn mower for an extended period, it’s essential to drain and dispose of the old gas properly. Draining the gas tank can be a bit tricky, but it’s a crucial step in maintaining your lawn mower’s engine and preventing damage. Here’s a step-by-step guide on how to drain and dispose of old gas:
- Locate the drain plug: The drain plug is usually located at the bottom of the fuel tank. Consult your lawn mower’s manual to find the exact location of the drain plug.
- Use a gas can: Use a gas can to collect the old gas. Make sure the gas can is specifically designed for gasoline and is in good condition.
- Drain the tank: Open the drain plug and allow the old gas to flow into the gas can. Be careful not to spill any gas on the ground or on your skin.
- Dispose of the old gas: Once you’ve drained the tank, dispose of the old gas properly. You can take it to a local recycling center or an auto parts store that accepts used gas.
Preventing Stale Fuel in the Future
Preventing stale fuel in the future is crucial to maintaining your lawn mower’s engine and preventing damage. Here are some tips to help you prevent stale fuel:
* Use a fuel stabilizer: Fuel stabilizers can help prevent the breakdown of gasoline and reduce the formation of gum, varnish, and other deposits.

To avoid these problems, it’s essential to drain the gas from your lawn mower if you won’t be using it for an extended period. You can drain the gas tank by locating the drain plug, usually found at the bottom of the tank, and allowing the gas to flow into a container. Alternatively, you can use a siphon hose to remove the gas from the tank. It’s also a good idea to add a fuel stabilizer to the gas tank to prevent the gas from breaking down and to keep the engine and fuel system clean. By taking these steps, you can help ensure your lawn mower runs smoothly and efficiently when you need it.
How do I properly drain the gas from my lawn mower?
Draining the gas from your lawn mower is a relatively simple process that requires some basic tools and precautions. First, make sure you have a container to hold the gas, and that it’s placed on a level surface to prevent spills. Next, locate the drain plug or fuel line, and use a wrench or pliers to loosen it. Be careful not to spill any gas on your skin or surfaces, as it can be hazardous. Once the gas starts flowing, you can use a siphon hose to speed up the process and minimize spills.
It’s essential to follow proper safety precautions when draining gas from your lawn mower. Wear protective gloves and eyewear to prevent exposure to gas fumes and spills. Also, make sure the area is well-ventilated, and avoid smoking or using open flames nearby. After draining the gas, dispose of it properly by taking it to a recycling center or an authorized hazardous waste facility. Don’t pour the gas down the drain or dispose of it in the trash, as it can harm the environment and contaminate soil and water. By following these steps and taking necessary precautions, you can safely and effectively drain the gas from your lawn mower.
Can I use old gas in my lawn mower, or should I dispose of it?
