How long can diesel be stored?
FAQs → How long can diesel be stored?
Generally, high-quality diesel fuel that meets ASTM standards can be stored for up to 6-12 months if properly handled and stored.
However, diesel fuel can degrade over time due to oxidation, contamination, or biological growth, which affects its quality, performance, and shelf life.
Storage Conditions: Diesel should be stored in a well-ventilated area, away from direct sunlight, heat sources, and ignition sources. Use a clean, dry tank with a tight-fitting lid or cap to prevent contamination. The ideal storage temperature is between 60°F and 80°F (15°C and 27°C).
Quality of the Diesel: Freshly refined diesel typically has a better storage life than older or used diesel. Check the fuel's flash point, which should be at least 125°F (52°C) to ensure it meets minimum safety standards.
Handling Practices: Handle diesel carefully to prevent contamination and minimize exposure to air. Avoid stirring or agitating the fuel, as this can introduce oxygen and accelerate degradation. If you notice any signs of spoilage, such as unusual odors, colors, or sedimentation, it's best to discard the fuel and replace it with fresh stock.
In summary, high-quality diesel fuel can last up to 6-12 months when properly stored and handled. Regularly monitor its condition and take steps to maintain its quality to ensure reliable performance in emergency situations.
