Quick Answer
Blending gasoline with ethanol is generally safe for storage, but proper handling and storage procedures must be followed to prevent phase separation and maintain fuel quality.
Understanding E10 and E15 Storage Considerations
When storing gasoline blends with ethanol, the water content is a critical factor. Ethanol blends can absorb moisture from the air, which can lead to phase separation and affect fuel quality. For E10 (10% ethanol) blends, a maximum water content of 400 ppm (parts per million) is recommended to prevent phase separation. In contrast, E15 (15% ethanol) blends require a maximum water content of 200 ppm.
Safe Storage Practices for Ethanol Blends
To ensure safe storage of gasoline blends with ethanol, follow these guidelines: Store them in sealed containers to prevent moisture absorption, and keep the storage area well-ventilated to prevent the accumulation of volatile organic compounds (VOCs). Regularly inspect the storage containers for signs of damage, rust, or corrosion, which can compromise the integrity of the container. Additionally, consider installing a fuel stabilization system to remove water and prevent phase separation.
Storage Considerations for Specific Environments
In areas with high humidity or extreme temperatures, additional precautions are necessary when storing ethanol blends. In humid environments, consider using a desiccant to control moisture levels in the storage area. In cold temperatures, ensure the storage area is well-insulated to prevent fuel from freezing and causing phase separation.
