Quick Answer
Using ethanol-free gasoline provides a longer shelf life, reduces water absorption, and minimizes corrosion in generator storage, making it suitable for long-term storage.
Reduced Water Absorption
Ethanol-free gasoline is less prone to water absorption, which is a major concern when storing fuel for extended periods. Water can mix with gasoline and cause phase separation, leading to fuel degradation and potential engine damage. By using ethanol-free gasoline, you can minimize this risk and ensure a longer shelf life. In fact, ethanol-free gasoline can last for up to 12 months when stored properly, compared to 6-9 months for ethanol-blended fuel.
Minimized Corrosion
Ethanol-free gasoline also reduces the risk of corrosion in generator storage. Ethanol can mix with fuel additives and cause corrosion in metal parts, leading to costly repairs and downtime. By using ethanol-free gasoline, you can prevent corrosion and ensure your generator remains in good working condition. To further minimize corrosion, it’s essential to store your generator in a dry, well-ventilated area and keep the fuel tank tightly sealed.
Generator Storage Techniques
When storing a generator for an extended period, it’s essential to follow proper storage techniques to ensure the fuel remains fresh and the engine remains in good working condition. This includes storing the generator in a dry, well-ventilated area, keeping the fuel tank tightly sealed, and using a fuel stabilizer to prevent degradation. For long-term storage, it’s recommended to store the generator with a full tank of ethanol-free gasoline and a fuel stabilizer, and to run the engine for 15-30 minutes every 2-3 months to circulate the fuel and maintain engine health.
