How to Put Gas in a Honda Lawn Mower?

The warm weather is finally here, and you’re ready to tackle your lawn. But before you can get started, you need to fuel up your trusty Honda lawnmower. This might seem like a simple task, but there are a few key things to remember to ensure you’re doing it right and keeping your mower running smoothly. This guide will walk you through the process of safely and efficiently putting gas in your Honda lawn mower, from understanding fuel types to proper handling techniques.

A Quick Overview

Putting gas in a Honda lawnmower is a straightforward process, but it’s essential to use the right type of fuel and follow safety precautions. This article will guide you through the steps, covering everything from finding the fuel tank to the best practices for filling it.

Finding the Fuel Tank

Before you can fill your mower with gas, you need to locate the fuel tank. This is typically located on the side or the top of the mower, often near the engine. Look for a small, rectangular or cylindrical opening with a cap on it. This cap will usually have a symbol that looks like a gas pump, making it easy to identify.

Choosing the Right Fuel

One of the most important things to remember when filling your Honda lawnmower is to use the right type of fuel. Honda recommends using unleaded gasoline with an octane rating of 87 or higher.

Why Unleaded?

Leaded gasoline contains lead, which can damage the delicate components of your mower’s engine. Over time, lead can build up and cause:

  • Spark plug fouling: This occurs when lead deposits accumulate on the spark plugs, preventing them from igniting the fuel properly.
  • Engine damage: Lead can also harm the piston rings, valves, and other critical engine parts.

Octane Rating

The octane rating of gasoline refers to its resistance to knocking or pinging. A higher octane rating generally means the fuel is more resistant to knocking. While Honda lawnmowers can run on gasoline with an octane rating of 87, using a higher octane (like 89 or 91) won’t hurt and may even improve performance, especially in hot weather.

Avoid Ethanol

While ethanol is often blended into gasoline to reduce emissions, it can be harmful to small engines like those in lawnmowers. Ethanol attracts moisture, which can lead to:

  • Phase separation: This happens when the ethanol and gasoline separate, creating a layer of water at the bottom of the fuel tank.
  • Engine corrosion: Water in the fuel can cause rust and corrosion, damaging engine components.

If possible, choose gasoline blends with low ethanol content (10% or less). If you can’t find low-ethanol gas, consider adding a fuel stabilizer to help prevent ethanol-related problems.

Filling the Fuel Tank

Once you’ve located the fuel tank and chosen the right type of gasoline, you can start filling it.

Safety First!

  • Turn off the mower: This is an essential safety precaution to prevent accidental ignition.
  • Keep the mower in a well-ventilated area: Gasoline fumes are flammable and can be dangerous in enclosed spaces.
  • Avoid smoking: Never smoke while handling gasoline.

Filling the Tank

  1. Gently unscrew the fuel cap: Be careful not to overtighten it when replacing the cap.
  2. Slowly pour gasoline into the tank: Don’t overfill the tank, as this can lead to spills and fuel evaporation. Most lawnmowers have a vent tube that allows air to escape as you fill the tank. Stop filling when you reach the bottom of the vent tube.
  3. Wipe up any spills: If you spill any gasoline, clean it up immediately using a cloth or paper towels.
  4. Tighten the fuel cap securely: Ensure it’s completely closed to prevent leaks.

Storing Your Mower

After you’re finished mowing, it’s important to store your Honda lawnmower properly.

  • Allow the mower to cool down: Don’t store a hot mower, as this can increase the risk of fire.
  • Empty the fuel tank: If you plan on storing the mower for an extended period, it’s best to drain the fuel tank to prevent the gas from going bad.
  • Add a fuel stabilizer: This helps prevent the gas from deteriorating and keeps the engine running smoothly.
  • Store the mower in a dry, well-ventilated area: Avoid storing the mower in direct sunlight or in damp conditions.

Troubleshooting

  • Engine won’t start: If your mower won’t start, there are a few common reasons:
    • Empty fuel tank: Make sure the fuel tank has gas.
    • Dirty air filter: A dirty air filter can restrict airflow to the engine. Clean or replace the filter.
    • Clogged fuel line: If the fuel line is clogged, the fuel can’t reach the engine. Check the fuel line for blockages.
  • Engine runs rough: If your mower runs rough, the problem might be:
    • Bad gas: Old gas can clog the fuel system. Use fresh gas or add a fuel stabilizer.
    • Dirty carburetor: A dirty carburetor can prevent the engine from running smoothly. Clean or replace the carburetor.
  • Mower smokes: If your mower smokes, it could be a sign of:
    • Oil leak: Check for oil leaks around the engine.
    • Burning oil: If the mower is burning oil, it could be a sign of a worn engine or a problem with the piston rings.

Conclusion

Putting gas in your Honda lawnmower is a simple but crucial step in keeping your mower running smoothly. By understanding the right fuel type, following safety precautions, and storing your mower properly, you can ensure that your Honda lawnmower is ready to tackle any lawn care task. Remember, if you encounter any issues, don’t hesitate to consult your owner’s manual or seek professional assistance. Happy mowing!

FAQs

What kind of gas should I use in my Honda lawn mower?

You should always use regular unleaded gasoline with a minimum octane rating of 87. Avoid using gasoline with ethanol, as it can damage the fuel system over time. It’s also essential to use fresh gasoline; older gasoline can become stale and gum up the engine.

Always make sure to check the owner’s manual for specific fuel recommendations for your particular Honda lawn mower model. Some newer models may be compatible with ethanol-blended fuels.

Where should I put the gas in my Honda lawn mower?

The gas tank on a Honda lawn mower is typically located on the side or top of the mower deck. Look for a cap with a symbol resembling a gas pump or a fuel can.

It’s crucial to ensure that the lawnmower is switched off and has cooled down before adding fuel. Never top off the tank, as this can cause fuel to spill over and create a fire hazard.

How much gas can I put in my Honda lawn mower?

The capacity of the gas tank will vary depending on the model. Consult your owner’s manual to determine the exact capacity.

It is generally recommended to only fill the tank about three-quarters full to leave room for expansion and prevent spills.

Can I use a gas can with a built-in funnel?

Yes, you can use a gas can with a built-in funnel to fill the tank. However, be careful not to overfill the tank.

If you are using a separate funnel, make sure it is designed for gasoline and that it fits securely in the tank opening.

Should I add fuel stabilizer to my Honda lawn mower?

Adding fuel stabilizer is recommended, especially if you don’t use your mower frequently. Fuel stabilizer helps prevent gasoline from degrading and gumming up the fuel system.

It is typically added to the gas tank before filling it up, and the recommended amount will be listed on the stabilizer product’s label.

What should I do if I accidentally spill gas on my Honda lawn mower?

If you spill gas on your lawn mower, immediately clean it up using a dry cloth or paper towels. Avoid using any type of flammable liquids to clean up the spill.

If the spill is significant, or if you are unsure how to clean it up safely, consult the owner’s manual or contact a qualified technician.

What should I do if my Honda lawn mower won’t start after adding gas?

If your Honda lawn mower won’t start after adding gas, there are a few things to check:

  • Ensure the gas cap is securely closed.
  • Check the fuel lines for any leaks.
  • Verify that the spark plug is properly connected and in good condition.
  • If the engine is flooded, you may need to remove the spark plug and crank the engine to clear the excess fuel.

If you are still unable to start the mower, it’s best to contact a qualified technician for assistance.
