In a nutshell: Getting old gasoline out of a lawn mower involves draining the existing fuel, cleaning the tank and fuel lines, and potentially replacing the fuel filter. This process is essential for restoring your mower’s performance and preventing damage to its internal components.
Why Is Old Gasoline Such a Problem?
The main culprit behind a lawn mower’s reluctance to start after a long winter slumber is gasoline deterioration. Gasoline isn’t a stable substance – it starts breaking down the moment it’s exposed to air, becoming less volatile and less effective.
The Breakdown Process
- Evaporation: Gasoline contains volatile hydrocarbons that evaporate over time, reducing its combustibility.
- Oxidation: Oxygen reacts with the hydrocarbons in gasoline, forming gum and varnish that can clog fuel lines and injectors.
- Water Contamination: Moisture in the air can condense within the gas tank, leading to water accumulation that further hinders ignition.
The Consequences of Old Gasoline
- Difficulty Starting: Old gas simply doesn’t burn as efficiently, making it harder to start the mower.
- Engine Performance Issues: The gum and varnish can obstruct fuel flow, leading to sputtering, hesitation, and a decrease in power.
- Damage to Components: Old gas can corrode internal parts of the engine, leading to costly repairs.
The Removal Process: A Step-by-Step Guide
Now that you understand the perils of old gas, let’s get down to business and remove it from your mower.
Safety First: Essential Precautions
Before you begin, it’s crucial to prioritize your safety:
- Work in a well-ventilated area. Gasoline vapors are flammable and dangerous to inhale.
- Use proper safety gear. Wear gloves and eye protection to prevent contact with gasoline.
- Keep away from open flames and heat sources.
Step 1: Draining the Old Fuel
- Locate the fuel tank. This is typically found on the side or top of the mower.
- Find the fuel drain valve. It’s often a small screw or knob near the bottom of the tank.
- Position a suitable container. Use a clean, sealed container to catch the drained gasoline.
- Open the drain valve. Carefully turn the valve to drain the fuel into the container.
- Tighten the valve. Once the fuel is drained, tighten the valve securely.
Step 2: Cleaning the Fuel Tank
- Remove the fuel tank. You may need to detach the tank from the mower or use a wrench to loosen the fuel line connection.
- Thoroughly clean the tank. Use a mild detergent and warm water to clean the inside of the tank. Avoid harsh chemicals that could damage the plastic or metal.
- Rinse the tank thoroughly. Ensure all traces of detergent and old gasoline are removed.
- Allow the tank to dry completely. This might take a few hours, depending on the size and shape of the tank.
Step 3: Cleaning the Fuel Lines
- Disconnect the fuel line. Locate the fuel line that connects to the carburetor.
- Clean the line. Use compressed air to blow out any debris or residue in the fuel line. If it’s a plastic line, be careful not to apply excessive pressure.
- Reconnect the fuel line. Ensure it’s properly attached to the carburetor.
Step 4: Replacing the Fuel Filter (Optional)
- Locate the fuel filter. It’s usually located between the fuel tank and the carburetor.
- Remove the old filter. Carefully detach the filter and discard it.
- Install a new filter. Ensure the new filter is compatible with your mower model.
Restarting Your Mower: A Fresh Start
With the old gasoline removed and the fuel system cleaned, you’re ready to fire up your mower.
- Pour fresh gasoline into the tank. Use a high-quality, ethanol-free gasoline for optimal performance.
- Prime the carburetor (if necessary). Some mowers have a priming bulb or lever that you can use to manually send fuel to the carburetor.
- Turn the key to the “on” position.
- Pull the starter cord. If the mower doesn’t start immediately, try again, and don’t over-pull the cord.
Preventative Measures: Keeping Your Mower Fuel Fresh
Now that your mower is back in working order, let’s explore ways to prevent old gas from becoming a recurring problem.
1. Use Fuel Stabilizer
Fuel stabilizers are additives that slow down the deterioration process of gasoline.
- Add stabilizer to the tank before storing. This will help to preserve the fuel quality for longer periods.
- Follow the manufacturer’s instructions. Use the recommended amount of stabilizer for your type of gasoline.
2. Store Your Mower Properly
- Empty the fuel tank. If you’re not going to use the mower for a while, drain the gas tank to prevent it from deteriorating.
- Store in a cool, dry place. Extreme temperatures can accelerate gasoline breakdown.
3. Keep a Close Eye on the Fuel
- Check the fuel level regularly. Don’t let the fuel sit in the tank for too long.
- Replace the fuel filter at least once a year. This helps to prevent fuel contamination.
Conclusion: A Fuel-Free Future for Your Mower
By diligently removing old gasoline, cleaning the fuel system, and employing preventative measures, you can ensure that your lawn mower is ready to tackle any mowing challenge, season after season. Enjoy the peace of mind knowing that your mower is in top condition, and your lawn is looking its best.
Frequently Asked Questions
What is the best way to get old gasoline out of my lawnmower?
The best way to get old gasoline out of your lawnmower is to use a siphon. You can find siphons at most hardware stores. Simply insert the siphon into the gas tank and then suck on the other end to start the flow. If you don’t have a siphon, you can try to drain the tank by tilting the mower on its side and letting the gas run out. However, this method is not always effective and can be messy.
How long does gasoline last in a lawnmower?
Gasoline can last for several months if it is stored properly. However, it will start to degrade after a year, and it will be unusable after two years. If you have gasoline in your lawnmower that is more than a year old, it’s best to drain it and replace it with fresh gasoline.
What are the signs of bad gasoline in a lawnmower?
There are several signs that your gasoline may be bad. The most obvious sign is that your lawnmower won’t start. Other signs include difficulty starting, sputtering, and a loss of power. If you notice any of these signs, it’s time to drain your gasoline and replace it with fresh gasoline.
What should I do with old gasoline?
Old gasoline can be hazardous, so it’s important to dispose of it properly. Don’t pour it down the drain or into the ground. Instead, take it to a local recycling center or hazardous waste disposal facility. You can also mix it with cat litter or sawdust to absorb it and then throw it away in the trash.
Can I use old gasoline in my car?
No, you should never use old gasoline in your car. It can damage your engine and cause a variety of problems. If you have old gasoline, it’s best to dispose of it properly.
How can I prevent old gasoline from forming in my lawnmower?
The best way to prevent old gasoline from forming in your lawnmower is to use it regularly. If you don’t use your lawnmower often, you can add a fuel stabilizer to the gas tank. This will help to prevent the gasoline from degrading. You can also store your lawnmower in a cool, dry place.
What are some alternatives to gasoline for lawnmowers?
