Tips for Long-Term Diesel Storage

Based in Riverside, the Inland Empire, and Southern California

Diesel fuel is an important component for industries operating heavy machinery, generators, and off-road vehicles. For businesses planning long-term diesel storage, maintaining fuel quality can greatly help prevent equipment damage and ensure reliable performance. Here are several tips to ensure diesel remains usable over extended periods, particularly in regions like Riverside and the Inland Empire, where fuel plays a vital role in construction, agriculture, and industrial operations.

Choosing the Right Storage Tank

Utilizing high-quality storage tanks is the initial step to preserving diesel. Tanks made from corrosion-resistant materials, such as stainless steel or specially treated plastics, are ideal. They should be properly sealed to prevent air and moisture intrusion, which can degrade fuel. Choose tanks with appropriate capacity to avoid overstocking and excessive storage times, which can lead to fuel deterioration.

Maintain Cool and Dry Storage Tanks

Environmental factors have a large impact on diesel quality. Tanks should be stored in shaded or temperature-controlled areas to minimize heat exposure, as high temperatures accelerate oxidation and fuel breakdown. In areas like the Inland Empire, where summers can be hot, consider installing insulation or protective coverings for tanks. Keeping the tanks dry also reduces the risk of contamination.

Add Stabilizers and Biocides

Diesel fuel naturally degrades over time due to microbial growth and oxidation. Adding stabilizers extends the fuel’s shelf life by reducing the risk of oxidation, while biocides inhibit bacteria and fungi that can form sludge and clog filters. Regular treatment with these additives ensures that the fuel remains in optimal condition.

Monitor and Maintain Regularly

Long-term storage requires consistent monitoring to detect and address issues early. Inspect tanks for leaks, corrosion, or sediment buildup, and test the diesel for water content and other impurities. Draining water from the tank’s bottom regularly prevents microbial growth, as water is a breeding ground for bacteria.

Rotate Stored Diesel

Using the “first in, first out” approach ensures older diesel is used before it begins to degrade. Rotating fuel stock helps maintain freshness and reduces the risk of waste. Reliable fuel delivery services such as Wood Oil Company can help businesses in Riverside and the Inland Empire manage their diesel supply efficiently.
