Understanding Bad Gas in Lawn Mowers
Bad gas can prevent your lawn mower from performing well. Knowing what causes it and how to identify it is crucial for proper maintenance and operation.
Causes of Bad Gas
- Age of Fuel: Gasoline loses its effectiveness after 30 days. Stale fuel can cause starting issues.
- Water Contamination: Water can mix with fuel from condensation or improper storage, leading to corrosion and engine problems.
- Additive Degradation: Fuel additives break down over time, reducing the fuel’s ability to keep your engine clean.
- Poor-Quality Fuel: Low-quality gasoline may contain impurities that affect engine performance.
- Difficulty Starting: Struggling to start the mower often signifies stale or contaminated fuel.
- Rough Idling: If the mower runs unevenly or stalls when idling, this may indicate bad gas.
- Reduced Power: Experiencing a significant drop in power during operation points to issues with the fuel quality.
- Unusual Smells: A strong odor of old or rotten fuel often accompanies bad gas.
Recognizing these causes and signs can help you tackle bad gas issues effectively.
How to Remove Bad Gas from Your Lawn Mower
Removing bad gas from your lawn mower restores performance and ensures smooth operation. Follow these steps to clear out the old fuel before refueling.
Steps to Drain the Fuel Tank
- Gather Supplies: Acquire a fuel siphon pump, plastic container, and safety gloves.
- Prepare the Mower: Turn off the mower and ensure it’s on a level surface. Let it cool down if it’s just been used.
- Locate the Fuel Tank: Identify the fuel tank’s cap on top of the mower.
- Siphon the Old Fuel: Insert the siphon pump into the tank and secure it. Begin siphoning the fuel into the plastic container. Stop when the tank is empty.
- Dispose of the Old Gas: Transfer the old gas to a local hazardous waste disposal site. Avoid pouring it down the drain or on the ground.
- Check the Fuel Lines: If possible, inspect the fuel lines for any remaining gas. Use a cloth to wipe any residue.
- Use Fuel Stabilizers: Add a fuel stabilizer when refilling to prevent future degradation.
- Change the Fuel Filter: Replace the fuel filter annually to keep the fuel system clean and effective.
- Inspect the Carburetor: Clean the carburetor periodically to remove deposits from old fuel and prevent clogging.
- Run the Mower Regularly: Operate the mower every few weeks during the season to ensure fresh fuel circulation.
- Store Fuel Properly: Store gasoline in approved containers and avoid additives that can deteriorate quickly.
Preventing Bad Gas in the Future
Maintaining fresh fuel and proper storage habits helps prevent bad gas in your lawn mower. Implementing a few simple practices ensures smoother operation and a longer mower lifespan.
Best Practices for Fuel Storage
- Use Fuel Stabilizers: Add fuel stabilizers to your gas when storing it. These additives keep fuel fresh and prevent degradation.
- Store in a Cool, Dry Place: Keep fuel containers away from direct sunlight and heat sources. Temperature fluctuations can adversely affect fuel quality.
- Seal Containers Properly: Always tighten caps on fuel containers. Properly sealed containers help reduce oxidation and moisture ingress.
- Rotate Your Fuel: Use fuel on a first-in, first-out basis. This practice helps ensure you use older fuel before it goes bad.
- Avoid Filling Fuel to the Brim: Leave some space in the container to allow for expansion. This prevents spills and maintains consistent pressure inside the container.
- Use Fresh Fuel: Buy gas that’s no more than 30 days old. Fresh fuel enhances starting and performance.
- Opt for Ethanol-Free Fuel: Ethanol can attract moisture and lead to engine issues. Using ethanol-free fuel minimizes these risks.
- Check Octane Ratings: Follow the manufacturer’s recommendation. Using the right octane level ensures optimal engine performance.
- Avoid Cheap Gas: Lower-quality fuel often contains impurities. Invest in reputable brands to secure cleaner combustion and engine health.
- Limit Fuel Mixing: Avoid mixing different types of gas. Stick to one type to ensure uniform composition and avoid combustion problems.
When to Consult a Professional
If you encounter persistent issues with your lawn mower that go beyond typical maintenance, seeking a professional’s help might be necessary. Certain signs indicate that your mower needs attention from someone with expertise.
Signs You Need Professional Help
- Continuous Starting Problems: If your mower often fails to start or starts inconsistently despite your troubleshooting, it signals a deeper issue.
- Increased Smoke Emission: Thick, excessive smoke from the exhaust indicates potential engine problems that require further investigation.
- Unusual Noises: Strange sounds, such as knocking or grinding, could mean serious internal damage that only a technician can assess.
- Fuel Leaks: Discovering fuel spills around your mower points to potential leaks in the fuel lines or tank, necessitating immediate inspection.
- Poor Performance After Fuel Change: If your mower still struggles even after removing bad gas and replacing it with fresh fuel, the problem likely lies elsewhere.
- Check Certifications: Look for a technician with certifications from recognized organizations in the industry, ensuring they have proper training to handle mower issues.
- Seek Recommendations: Ask friends, family, or local gardening clubs for referrals to trusted technicians with a good track record.
- Read Reviews: Online platforms like Google or Yelp provide customer feedback, helping you gauge the reliability and quality of service from various technicians.
- Inquire About Experience: Prioritize technicians with experience specifically related to lawn mower repairs to ensure they can effectively diagnose and fix your mower.
- Request Estimates: Get quotes from multiple technicians before making a decision, allowing you to compare prices and services offered.
These steps will help you address complex issues with your lawn mower and ensure proper functioning for future use.
