Quick Answer
Ethanol-blend fuel can cause more problems in storage due to its corrosive properties and tendency to absorb moisture from the air, which can lead to phase separation and spoilage.
Storage Considerations for Ethanol-Blend Fuel
Storing ethanol-blend fuel for long periods requires extra precautions to prevent degradation. In the United States, the most common ethanol-blend fuel is E10, which contains 10% ethanol. However, some generators and equipment may require E0 or pure gasoline to function properly. It’s essential to check the manufacturer’s recommendations before storing ethanol-blend fuel for extended periods.
Corrosion and Moisture Issues
Ethanol-blend fuel’s corrosive properties can damage storage containers, pumps, and other equipment. To mitigate this risk, use only fuel-grade storage containers and ensure they are designed for ethanol-blend fuel storage. The storage containers should also have a tight seal to prevent moisture from entering. When storing large quantities of ethanol-blend fuel, consider using a fuel tank with a floating roof to minimize contact between the fuel and air.
Best Practices for Long-Term Storage
When storing ethanol-blend fuel for long periods, it’s crucial to follow best practices to minimize degradation and spoilage. Store the fuel in a cool, dry place, away from direct sunlight and heat sources. The storage area should also be well-ventilated to prevent the buildup of flammable vapors. Regularly inspect the storage containers and fuel for signs of spoilage, such as a dark or cloudy appearance, or a strong, unpleasant odor. If you notice any of these signs, it’s best to dispose of the fuel and replace it with fresh, high-quality ethanol-blend fuel.
