As the warmer months approach, many of us are eager to get our lawn mowers ready for the cutting season. However, if you’re like most people, you might be wondering how long the gas in your lawn mower will remain usable. The shelf life of gasoline is a critical factor to consider, as it can affect the performance and longevity of your lawn mower. In this article, we’ll delve into the world of gasoline and explore how long it stays good in a lawn mower, as well as provide valuable tips on maintenance and storage.
Understanding Gasoline Shelf Life
Gasoline is a volatile liquid that can deteriorate over time, leading to a decrease in its quality and performance. The shelf life of gasoline depends on various factors, including the type of gas, storage conditions, and the presence of additives. Typically, gasoline can last for several months to a few years when stored properly. However, it’s essential to note that gasoline can break down and form gums, varnishes, and other deposits that can clog fuel lines and damage engine components.
Factors Affecting Gasoline Shelf Life
Several factors can influence the shelf life of gasoline in your lawn mower. These include:
The type of gasoline used, with some types being more prone to degradation than others
The storage conditions, such as temperature, humidity, and exposure to light
The presence of additives, such as stabilizers and detergents, that can help extend the shelf life
The age of the gasoline, with older gas being more likely to deteriorate
The Role of Additives
Gasoline additives play a crucial role in maintaining the quality and performance of the fuel. Stabilizers, such as those containing tertiary butyl hydroperoxide, can help prevent the formation of gums and varnishes. Detergents, on the other hand, can help clean the engine and fuel system, reducing the risk of clogs and damage. When choosing a gasoline additive, look for products that are specifically designed for small engines, such as those used in lawn mowers.
Maintenance and Storage Tips
To ensure your lawn mower runs smoothly and efficiently, it’s essential to follow proper maintenance and storage procedures. Here are some valuable tips to keep in mind:
Regularly check and maintain the oil and filter in your lawn mower
Store the lawn mower in a cool, dry place, away from direct sunlight and moisture
Use a fuel stabilizer to help prevent the formation of gums and varnishes
Drain the fuel tank and run the engine dry before storing the lawn mower for an extended period
Draining the Fuel Tank
Draining the fuel tank is an essential step in preparing your lawn mower for storage. This helps prevent the formation of condensation, which can lead to rust and corrosion. To drain the fuel tank, follow these steps:
Locate the fuel drain plug or valve, usually found at the bottom of the fuel tank
Open the valve or remove the plug, allowing the fuel to drain into a container
Replace the plug or close the valve, making sure it’s securely tightened
Running the Engine Dry
Running the engine dry is another crucial step in preparing your lawn mower for storage. This helps prevent the formation of gums and varnishes, which can clog fuel lines and damage engine components. To run the engine dry, follow these steps:
Locate the fuel shut-off valve, usually found near the fuel tank
Open the valve, allowing the engine to run until it stalls
Close the valve, making sure it’s securely tightened
