Removing old gas from a lawn mower is an essential maintenance task that can help ensure the longevity and performance of your equipment. Over time, gasoline can break down and leave behind deposits that can clog the fuel system, cause engine problems, and even lead to safety hazards. In this article, we will walk you through the steps to remove old gas from a lawn mower, highlighting the importance of proper safety precautions, the right tools, and techniques to get the job done efficiently.
Understanding the Risks of Old Gas in a Lawn Mower
Leaving old gas in a lawn mower can have serious consequences. Gasoline is a volatile liquid that can evaporate quickly, leaving behind a mixture of varnish, gum, and other deposits that can clog the fuel system. These deposits can cause a range of problems, including engine sputtering, misfiring, and stalling. Additionally, old gas can also attract moisture, leading to corrosion and rust in the fuel tank and other metal components. To avoid these problems, it’s essential to remove old gas from your lawn mower regularly, especially if you won’t be using it for an extended period.
Preparation is Key
Before you start removing old gas from your lawn mower, make sure you have the necessary tools and equipment. You will need a fuel drain pan, a pair of gloves, safety goggles, and a soft cloth. It’s also a good idea to consult your lawn mower’s owner’s manual to see if there are any specific recommendations for draining the fuel tank. Make sure you are in a well-ventilated area, away from any open flames or sparks, as gasoline fumes can be hazardous to your health.
Disconnecting the Spark Plug
To prevent any accidental starts, it’s essential to disconnect the spark plug wire from the spark plug. This will disable the engine and prevent any fuel from flowing through the system. Locate the spark plug wire and pull it off the spark plug. You may need to use a spark plug wire puller to remove the wire. Once the wire is disconnected, you can proceed with draining the fuel tank.
Draining the Fuel Tank
Draining the fuel tank is the most critical step in removing old gas from a lawn mower. There are several ways to drain the fuel tank, depending on the type of lawn mower you have. Some lawn mowers have a drain plug located at the bottom of the fuel tank, while others may require you to siphon the gas out using a hose. Here’s a step-by-step guide on how to drain the fuel tank:
To drain the fuel tank using a drain plug, follow these steps:
- Locate the drain plug and position the fuel drain pan underneath it.
- Use a wrench or socket to loosen the drain plug, but do not remove it yet.
- Slowly turn the drain plug counterclockwise until the gas starts to flow out.
- Once the gas has stopped flowing, replace the drain plug and tighten it securely.
If your lawn mower does not have a drain plug, you may need to siphon the gas out using a hose. You can purchase a fuel siphon hose at most auto parts stores or online. To siphon the gas out, follow these steps:
To siphon the gas, simply insert the hose into the fuel tank and suck on the other end until the gas starts to flow. Be careful not to swallow any gas, as it can be hazardous to your health. Once the gas has stopped flowing, remove the hose and dispose of the gas properly.
Cleaning the Fuel System
After draining the fuel tank, it’s essential to clean the fuel system to remove any remaining deposits. You can use a fuel system cleaner to remove any varnish, gum, and other deposits that may have built up in the fuel system. Follow the instructions on the cleaner to ensure you use it correctly. You may also need to replace the fuel filter to ensure that any remaining deposits are removed.
Disposing of Old Gas
Disposing of old gas requires special care, as it can be hazardous to the environment. Never dispose of old gas in the sewer or storm drain, as it can contaminate waterways and harm aquatic life. Instead, take the old gas to a recycling center or an auto parts store that accepts used gasoline. Make sure to check with your local authorities to see if there are any specific regulations or guidelines for disposing of old gas in your area.
Preventing Old Gas from Building Up in the Future
To prevent old gas from building up in your lawn mower in the future, it’s essential to use a fuel stabilizer whenever you store your lawn mower for an extended period. A fuel stabilizer can help prevent gasoline from breaking down and forming deposits. You can also add a fuel additive to your gas to help clean the fuel system and prevent corrosion.
Conclusion
Removing old gas from a lawn mower is a straightforward process that requires some basic tools and equipment. By following the steps outlined in this article, you can help ensure the longevity and performance of your lawn mower. Remember to always use caution when handling gasoline, as it can be hazardous to your health and the environment. With proper maintenance and care, your lawn mower will run smoothly and efficiently for years to come.

How do I know if the gas in my lawn mower is bad?
Determining whether the gas in a lawn mower is bad can be done by checking its color, consistency, and smell. Good gas is typically clear or light yellow in color, while bad gas may appear darker, murkier, or have a thick, syrupy consistency. If the gas smells sour, stale, or has a strong, pungent odor, it’s likely gone bad. Another way to check is to start the lawn mower and see how it runs. If it stalls, sputters, or runs rough, the gas may be the culprit.
If you suspect the gas in your lawn mower is bad, it’s best to err on the side of caution and drain the tank. Bad gas can cause damage to the engine and fuel system, leading to costly repairs. To drain the tank, refer to the lawn mower’s owner’s manual for specific instructions, as the process may vary depending on the model and type of lawn mower. Once the tank is drained, refill it with fresh gas and add a fuel stabilizer to help prevent the gas from breaking down over time. This will help keep the lawn mower running smoothly and prevent problems down the road.
What is the best way to remove old gas from a lawn mower?
The best way to remove old gas from a lawn mower is to drain the fuel tank, as this will prevent any potential safety hazards and minimize the risk of engine damage. To do this, locate the fuel tank and find the drain plug or fuel line. Refer to the owner’s manual for specific instructions, as the process may vary depending on the model and type of lawn mower. Once you’ve accessed the fuel tank, use a siphon hose or a fuel drain pump to remove the old gas.
