What precaution should be taken when using gasoline containing alcohol?

Using gasoline that contains alcohol, such as ethanol, can indeed lead to corrosion of engine components. This is an important consideration for small engine maintenance and operation. Alcohol blended fuels can absorb moisture from the air, which can lead to the formation of water in the fuel system. This water can then promote corrosion in various metal parts of the engine, including fuel lines, carburetors, and fuel tanks.

Additionally, alcohol-containing fuels can degrade certain rubber and plastic components in the fuel system, leading to leaks or malfunctioning parts. The presence of alcohol can also impact the fuel's storage characteristics, potentially leading to issues if the fuel is stored for extended periods. Therefore, it is essential to take precautions when using alcohol-blended gasoline, such as using fuel stabilizers, ensuring proper storage conditions, and being aware of the materials in your engine that may be affected by these fuels.
