How to Dump Old Gas Out of Your Lawn Mower?

The season’s over, the leaves are raked, and your lawn mower sits idle in the garage. But before you tuck it away for the winter, there’s one important task you need to complete: getting rid of that old gas. Leaving stale fuel in your mower can lead to engine problems, costly repairs, and even dangerous situations. This article will guide you through the safe and environmentally friendly process of dumping old gas from your lawn mower, ensuring your trusty machine is ready for action next spring.

The Short Answer

The easiest way to get rid of old gas in a lawn mower is to carefully siphon it out using a siphon pump, then dispose of the fuel responsibly. It’s important to remember that gasoline is highly flammable, so you need to take necessary precautions to avoid any accidents.

Why You Should Dump Old Gas

Gasoline, unlike wine, doesn’t get better with age. Over time, it deteriorates, forming harmful deposits and gum that can clog your mower’s fuel system. This can lead to:

1. Difficulty Starting

Old gas can make it difficult to start your lawn mower. The gum and varnish can clog the fuel lines and carburetor, preventing the engine from getting the fuel it needs.

2. Engine Problems

Running a lawn mower on old gas can lead to engine problems such as sputtering, misfiring, and even complete engine failure. These problems can require costly repairs, leaving you frustrated and out of pocket.

3. Environmental Damage

Dumping old gas directly into the ground or down a drain can contaminate the soil and water supply. It’s crucial to dispose of gasoline responsibly, following local regulations and safety guidelines.

How to Dump Old Gas From Your Lawn Mower

Now that you understand the importance of removing old gas, here’s a step-by-step guide to safely dumping it from your lawn mower:

1. Prepare Your Work Area

Safety is paramount when working with gasoline. Here’s how to prepare for a smooth and safe process:

  • Find a well-ventilated area: Choose an open space away from any heat sources or flammable materials. Avoid working in enclosed spaces.
  • Wear protective gear: Always wear safety glasses, gloves, and closed-toe shoes to protect yourself from spills and fumes.
  • Have a fire extinguisher handy: Just in case!

2. Locate the Fuel Tank

The fuel tank is usually located on the side or top of your lawn mower. It might have a cap with a vent, or a cap with a fuel gauge.

  • Identify the fuel tank cap: Look for a round or square cap, often with a label indicating “fuel” or a gas pump symbol.
  • Release the fuel cap: Turn the cap counterclockwise to open it.

3. Siphon the Fuel

You’ll need a siphon pump to remove the gasoline from the tank. Here’s how to do it:

  • Choose a siphon pump: These are readily available at hardware stores or online. Look for a pump specifically designed for gasoline.
  • Attach the siphon hose: Connect the hose to the siphon pump, following the manufacturer’s instructions.
  • Insert the hose into the tank: Carefully insert the hose into the fuel tank, ensuring it reaches the bottom.
  • Start siphoning: Follow the instructions on the siphon pump to start the flow of gasoline.

4. Collect the Fuel

You’ll need a suitable container to collect the old gas. Here are some options:

  • Gasoline-approved container: Use a container specifically designed for storing gasoline, which is available at hardware stores or auto parts stores.
  • Metal can: Make sure the can is clean, dry, and free from any rust or damage.
  • Glass jar: Avoid using glass jars unless you are very careful. They can break easily, especially when handling flammable liquids.

Important Note: Never use plastic containers to store gasoline, as they can react with the fuel and become brittle.

5. Dispose of the Old Gas

Properly disposing of old gasoline is crucial to protect the environment. Here are the best ways to do it:

  • Local hazardous waste facility: Contact your local waste management agency to find a facility that accepts gasoline. They will have specific instructions for disposal.
  • Gas station: Some gas stations may accept small quantities of old gas for disposal. Contact them beforehand to check their policy.
  • Recycling program: Many communities offer programs for recycling used motor oil and other automotive fluids, which may include gasoline. Check your local recycling center for details.

Never:

  • Pour old gas down the drain.
  • Pour old gas on the ground.
  • Burn old gas.

These actions can pollute the environment and are illegal in many areas.

After Dumping the Gas

Once you’ve successfully removed the old gasoline, you’re not finished yet. Here are some final steps:

1. Clean the Tank

After removing the fuel, use a clean cloth to wipe down the inside of the fuel tank and the fuel cap to remove any residue.

2. Add Fresh Fuel

If you plan to use your lawn mower soon, fill the tank with fresh, high-quality gasoline.

3. Run the Engine

After filling the tank with fresh gas, run the engine for a few minutes to help clear out any remaining old fuel in the fuel lines and carburetor.

Tips for Preventing Old Gas Problems

Here are some tips for keeping your lawn mower’s fuel system healthy and preventing problems caused by old gas:

  • Use a fuel stabilizer: Add a fuel stabilizer to your gas tank before storing your lawn mower for extended periods. This helps prevent fuel deterioration and keeps your engine running smoothly.
  • Store the mower in a cool, dry place: Extreme temperatures and humidity can accelerate fuel deterioration. Store your mower in a well-ventilated area, out of direct sunlight.
  • Don’t fill the tank to the brim: Leave some space in the tank to allow for fuel expansion and prevent spills.

Conclusion

Dumping old gas from your lawn mower is an essential step in maintaining its health and extending its lifespan. By following the guidelines in this article, you can safely remove old fuel, dispose of it responsibly, and ensure your lawn mower is ready for action next season. Remember, safety and environmental awareness should be top priorities when working with gasoline.
