Maintaining a push mower is essential for ensuring it runs smoothly and lasts for years. One of the most crucial aspects of mower maintenance is choosing the right type of gas. Whether you’re using your mower for residential lawn care or part of larger general machinery for landscaping, selecting the appropriate fuel is critical for performance and longevity. In this article, we will discuss the types of gas suitable for push mowers, the pros and cons of different fuels, and tips on how to properly store fuel to keep your equipment running efficiently.
Types of Gas for Push Mowers
Push mowers, like other electrical equipment and environmental equipment, require specific types of fuel for optimal operation. When choosing fuel for your mower, it’s essential to understand the difference between regular gasoline and other alternatives. Typically, gasoline is the most common fuel used for small engines, but not all gasoline is suitable for your mower.
1. Regular Unleaded Gasoline
Regular unleaded gasoline, which you typically find at any gas station, is the most common type of fuel used in push mowers. It is designed for small engines like those found in lawn mowers, chainsaws, and other general machinery. Here’s what you need to know:
Octane Rating: Regular unleaded gas usually has an octane rating of 87, which is sufficient for most push mower engines.
Advantages: It is widely available and affordable, making it an easy choice for most homeowners.
Disadvantages: Regular unleaded gasoline can go bad over time, especially if left in the mower’s gas tank for long periods. It is more likely to cause engine problems like hard starting or stalling if not used promptly.
2. Premium Unleaded Gasoline
Premium unleaded gasoline has a higher octane rating, usually 91 or higher. While it’s not always necessary for a push mower, some high-performance models may benefit from using premium gasoline. Here’s a closer look:
Octane Rating: Premium gas typically has an octane rating of 91 or higher, which prevents engine knocking in high-performance machines.
Advantages: It may improve engine performance in some high-performance push mowers, especially those used for larger lawns or commercial purposes.
Disadvantages: It’s more expensive and may not provide any noticeable benefit for standard residential mowers. For most models, the added cost isn’t worth the slight performance increase.
3. Ethanol-Free Gasoline
Ethanol-free gasoline, also known as non-ethanol gas, is another option for your push mower. This type of fuel doesn’t contain ethanol, which is typically found in most gasoline sold in the U.S. Ethanol can be harmful to small engines, so using ethanol-free gasoline can prevent several common mower problems.
Advantages: Ethanol-free gas is cleaner for the engine and will prevent issues like clogging the carburetor or fuel lines. It also helps avoid the buildup of harmful deposits.
Disadvantages: It can be more expensive and harder to find than regular unleaded gasoline. Additionally, it still has a shelf life, so it needs to be used within a certain period to avoid degradation.
Why Does Fuel Type Matter for Your Push Mower?
Using the wrong type of fuel can cause a host of problems for your push mower. The engine may not run efficiently, and you could experience issues like:
Starting Problems: Poor fuel can cause your engine to be hard to start or may even prevent it from starting altogether.
Overheating: Low-quality or inappropriate fuel can cause your mower engine to overheat, which leads to costly repairs.
Reduced Engine Life: Prolonged use of the wrong fuel type can damage the internal components of the engine, reducing the overall life of the mower.
Environmental Impact: Using low-grade or incorrect fuel can result in higher emissions, making it less eco-friendly.
By understanding the role that different types of fuel play in your push mower’s performance, you can ensure that your equipment is running efficiently and will continue to serve you well.
How to Maintain Fuel for Your Push Mower
Proper fuel storage is just as important as choosing the right type of fuel. Storing fuel incorrectly can lead to a range of problems, including engine failure or the buildup of harmful substances that reduce the mower’s efficiency. Here are some tips on how to maintain fuel for your push mower:
1. Use Fresh Fuel
Gasoline deteriorates over time, especially when it’s left in the mower for extended periods. Fuel that’s been sitting in the tank for too long can cause starting problems, clog fuel lines, and even damage the engine. To avoid these issues, always use fresh fuel for your mower.
Shelf Life of Gasoline: Regular gasoline can last anywhere from 30 days to three months before it begins to break down. Ethanol-free gasoline has a longer shelf life, often up to 12 months, so it’s a better option for long-term storage.
Fuel Stabilizer: If you plan to store fuel for more than a month, consider using a fuel stabilizer. This additive helps prevent the fuel from breaking down and causing issues with the engine.
2. Store Gas in Proper Containers
Always store fuel in approved, airtight containers. Avoid using old, rusty containers that could contaminate the fuel and harm your push mower.
Gas Cans: Use plastic or metal gas cans that are clearly labeled for gasoline storage. These cans are designed to prevent fuel from evaporating and reduce the risk of leaks or spills.
Location: Store your fuel in a cool, dry place away from heat sources and direct sunlight. Fuel should never be stored in an enclosed space like a garage that could heat up during the summer months.
3. Empty the Gas Tank for Winter Storage
If you plan to store your push mower for the winter, it’s best to empty the gas tank. Fuel left in the tank can break down over time, especially in cold temperatures, leading to clogged lines and carburetor problems.
Drain the Fuel: Before storing your mower for the off-season, run the engine until the gas tank is empty. This helps prevent the fuel from breaking down and gumming up the engine.
Clean the Tank: If you have the time, clean the fuel tank and fuel lines to prevent any old fuel from lingering in the system.
Additional Tips for Push Mower Maintenance
Besides choosing the right type of fuel and storing it properly, regular maintenance of your push mower is crucial to keep it running efficiently. Here are some maintenance tips for keeping your mower in top shape:
1. Change the Oil Regularly
Just like with any other machinery, regular oil changes are essential for a push mower. This ensures the engine stays lubricated and runs smoothly, preventing overheating and wear.
2. Clean the Air Filter
A clogged air filter can reduce the mower’s performance and lead to engine failure. Clean or replace the air filter regularly to ensure proper airflow to the engine.
3. Sharpen the Blades
Dull blades can make mowing difficult and lead to uneven cuts. Sharpen the blades regularly to ensure clean, efficient cuts and reduce stress on the engine.
4. Check the Spark Plug
A faulty spark plug can prevent your mower from starting or cause it to run inefficiently. Check the spark plug periodically and replace it if necessary.
5. Inspect the Fuel Lines and Carburetor
Inspect the fuel lines and carburetor for leaks or blockages. Clean or replace these parts as needed to keep the fuel flowing smoothly to the engine.
Conclusion
When it comes to choosing the right type of gas for your push mower, it’s important to consider the specific needs of your equipment. Regular unleaded gasoline is the most common fuel used, but ethanol-free gasoline and premium gas can offer advantages for certain models. By understanding the different types of fuel available and properly maintaining your fuel, you can ensure that your push mower runs smoothly and efficiently for years to come. Proper fuel selection, storage, and regular maintenance will also help minimize environmental impact by reducing harmful emissions, making your equipment not only more efficient but also more eco-friendly. Keep your push mower in top condition by making the right fuel choice and performing regular upkeep.
