Understanding the Risks of Storing Gas in a Riding Mower
Storing a riding mower with gas in the tank can pose several risks, primarily due to the properties of gasoline and how they change over time. Gasoline is a volatile liquid that can degrade and separate into its various components when stored for extended periods. This degradation process can lead to the formation of gums, varnishes, and other contaminants that can clog the fuel system of your mower, including the carburetor, fuel injectors, and fuel lines.
The Effects of Gasoline Degradation
Gasoline degradation can have severe consequences on the performance and longevity of a riding mower. Phase separation is a common issue, where the gasoline separates into different layers, with the heavier components sinking to the bottom of the tank. This can cause the fuel to become stale and less effective, potentially leading to engine difficulties when you try to start the mower after a long storage period. Moreover, the corrosive properties of degraded gasoline can damage metal components within the fuel system, resulting in costly repairs.
Moisture and Condensation
Another critical factor to consider when storing a riding mower with gas is the risk of moisture accumulation. During the winter months, the temperature can fluctuate significantly, leading to condensation inside the fuel tank. This moisture can combine with the gasoline to form ethyl alcohol, which can attract more moisture and cause corrosion. The presence of water in the fuel system can also lead to the growth of bacteria and fungi, further contaminating the fuel and potentially causing engine problems.
