Quick Answer
Ethanol blended fuels can be stored for extended periods, but they require special handling and precautions to maintain their stability and prevent degradation.
Storage Considerations
When storing ethanol blended fuels, it’s essential to consider the storage container’s material and size. Steel or fiberglass tanks with a minimum capacity of 20 gallons are recommended to prevent contamination and minimize headspace. Always ensure the tank is clean and dry before filling with fuel.
Fuel Stability and Degradation
Ethanol blended fuels can degrade over time, particularly when exposed to heat, light, and oxygen. To minimize degradation, store fuel in a cool, dark location with minimal headspace. The ideal storage temperature range is between 40°F and 60°F (4°C and 15°C). Avoid storing fuel near direct sunlight, heat sources, or electrical equipment. Additionally, use a fuel stabilizer or additive to prevent gum and varnish formation.
Handling and Maintenance
Regular maintenance is crucial when storing ethanol blended fuels. Check the storage container for signs of leaks, rust, or corrosion. Inspect the fuel for sediment, water, or contamination. Replace the fuel every 6-12 months, depending on the storage conditions and the type of vehicle it’s intended for. Always follow the manufacturer’s instructions for fuel handling and storage.
