Tips to Drain Gas From Lawn Mower

Exercise caution and prioritize safety throughout the process to avoid accidents and mishaps. You should know how to drain gas from lawn mower, here are the tips:

Prepare the Necessary Tools and Materials:

Before starting the gas draining process, gather the necessary tools and materials.

Safety First:

Always prioritize safety when working with gasoline. Perform the gas draining process in a well-ventilated area outdoors, away from open flames, sparks, or other ignition sources.

Locate the Gas Tank:

Identify the gas tank on your lawn mower. It is typically located near the engine and is often made of plastic or metal. Refer to your mower’s user manual if unsure about the exact location.

Remove the Gas Tank Cap:

Be cautious as you remove the cap; it may release pressure if there is any built-up gas vapor.

Position the Collection Container:

Place the collection container below the gas tank, ensuring that it has sufficient capacity to hold all the gasoline that will be drained. Position it stably and securely to avoid any spills or accidents.

Start the Siphoning Process:

If using a fuel siphon, pump the bulb or squeeze the handle to initiate the flow of gasoline. If using a hand pump, start pumping to create suction and then easily draw the gas out of the tank. 

Ensure that the other end of the tube is inside the collection container to catch the draining gas.

Drain the Gas:

Allow the gasoline to drain fully from the tank into the collection container. Avoid any spillage or splashing during the process.

Dispose of the Gas Properly:

Once all the gas has been drained, you must handle its disposal responsibly. Contact your local waste facility or recycling center for guidance on how to dispose of the gas safely and legally.

Reinstall the Gas Tank Cap:

After draining the gas, securely reinstall the gas tank cap. Ensure it is tightened properly to prevent any leaks or evaporation of fuel. This step is crucial to maintaining the integrity of the mower’s fuel system.

Consider Fuel Stabilizer:

Fuel stabilizers prevent the gasoline from deteriorating, which can cause starting problems and engine damage. Follow the instructions on the stabilizer product for the recommended dosage and procedure.

Refill the Tank (optional):

If you plan to reuse the gasoline you drained, use a funnel to pour it back into the gas tank. Ensure the funnel is clean and free from any contaminants. Be careful not to spill any gas during the refill process, as it can be hazardous.

Other Methods to Drain Gas from Your Lawn Mower

Whether you want to store your lawn mower for the winter or perform repairs that require an empty tank, knowing how to drain gas from lawn mower is important.

Drain Plug Method:

Some lawn mowers are equipped with a drain plug, which provides a convenient way to remove the gas.

  • Using the appropriate tool, unscrew the drain plug slowly and carefully.
  • Allow the gas to drain completely into the container.
  • Once the gas has drained, securely tighten the drain plug back into place.

Run Until Empty Method:

You can use the run-until-empty method if you don’t have access to a siphoning tube or a drain plug. This method involves running the lawn mower until it consumes all the gas in the tank.

Follow these steps to use this method:

  • Position the lawn mower on a flat, level surface, ensuring it has enough space to run without obstacles.
  • Monitor the fuel gauge or inspect the gas tank to ensure it is empty.
  • Once the lawn mower has consumed all the gas, turn off the engine and proceed with the necessary maintenance or storage procedures.

Properly draining the gas from your lawn mower is essential for maintenance and storage. The siphoning method, drain plug method, and running until the empty method are three effective ways to achieve this. Now you know how to drain gas from lawn mower.

Choose the method that suits your equipment and available resources. Remember to follow safety guidelines and dispose of the drained gas properly.


How do you get gas out of a lawn mower without a siphon?

First, disconnect the spark plug wire to ensure the engine doesn’t start accidentally. Then, tilt the mower on its side with the gas tank positioned above the carburetor. Place a suitable container beneath the carburetor and remove the fuel line that connects to it.

How do you drain gas from a carburetor?

Locate the carburetor on the lawn mower to drain gas from the carburetor. Place a container underneath to catch the fuel. Unscrew the drain plug or screw and allow the gas to drain completely. Once drained, tighten the plug or screw securely. Always exercise caution and follow safety guidelines when working with gasoline.

Does gas evaporate from a lawn mower?

Yes, gasoline can evaporate from a lawn mower over time. This residue can clog the fuel system, including the carburetor, and hinder the mower’s performance. Regular maintenance and proper storage practices can help minimize evaporation and maintain the mower’s optimal functioning.


In conclusion, draining gas from a lawn mower is a relatively easy-to-follow process that requires some basic tools and precautions. Turn off your lawn mower and disconnect the spark plug wire to prevent accidental starts. 

Identify the gas tank on your lawn mower. It is usually positioned near the engine and can be a plastic or metal container. 

Tilt the lawn mower so the gas flows from the tank into the container. Be cautious not to spill any gas. Once the gas has been drained, take the container to a designated gas disposal facility or a recycling center that accepts gasoline. We hope now you know how to drain gas from lawn mower.
