Store in a cool, dark place

Diesel fuel is a highly stable and powerful energy source, widely used in commercial transportation, farming, and military applications. It is important to store diesel fuel properly to protect it from damage and contamination.

One of the key factors in extending the lifespan of diesel fuel is to store it in a cool, dark place, away from direct sunlight and heat sources. The ideal temperature for storing diesel is below 20 degrees Celsius, and it should be kept away from furnaces, water heaters, and other heat sources. By maintaining these optimum conditions, the degradation process can be slowed down, allowing the fuel to be stored for up to a year without any additives.

To further ensure the longevity of your diesel fuel, it is recommended to use well-constructed tanks or containers that are approved by the relevant authorities, such as portable tanks approved by the Department of Transportation (DOT). These tanks should be regularly cleaned to remove any pollutants or buildup, as a dirty tank can taint the fuel and reduce its shelf life. Additionally, it is important to monitor the condition of the fuel regularly, looking out for signs of degradation such as discolouration or increased water content.

By following these practices and storing diesel fuel in a cool, dark place, you can effectively extend its lifespan and ensure its quality and performance.

Use biocides and stabilizers

Biocides are chemical agents used to control the proliferation of harmful organisms in diesel fuel. They are often used to address fuel contamination, including microbial contamination, which can lead to fuel degradation, filter clogging, and equipment damage. To use a biocide effectively, it is important to follow these steps:

  • Choose the right biocide for your needs, such as Bio Kleen Diesel Fuel Biocide Treatment or Bellicide.
  • Calculate the correct amount of biocide required based on the volume of fuel and the recommended concentration. For example, Bellicide recommends a concentration of 1 ounce per 40 gallons of fuel.
  • Add the biocide to the fuel in the tank, ensuring that it mixes thoroughly and makes contact with all tank surfaces.
  • Fill the tank up to capacity with more fuel after adding the biocide.
  • Change the fuel filters regularly, as the biocide will kill microbes but their dead bodies can plug the fuel filters.

In addition to biocides, fuel stabilizers are also important for preserving diesel fuel. Stabilizers are used to prevent fuel degradation by inhibiting chemical reactions caused by exposure to water and air. When storing diesel fuel for long periods, it is recommended to use a fuel stabilizer in conjunction with a biocide to provide the best protection.

While biocides are effective in controlling microbial growth, they do not address the root cause of contamination, which is often water. Fuel filtration equipment offers a superior alternative by mechanically removing water and solid contaminants from diesel fuel, preserving fuel quality, and protecting engine components. Therefore, a combination of biocides, stabilizers, and fuel filtration may be the best approach to preserving diesel fuel.

Avoid water and other contaminants

Water contamination is a serious issue that can occur in diesel fuel storage tanks. Water buildup can cause microbial contamination, which can lead to a reduction in fuel quality and even render the tank nearly unusable for storing diesel. Therefore, it is important to avoid water contamination and other contaminants to preserve diesel fuel effectively.

Firstly, it is crucial to choose the right storage tank or container. Opting for a well-constructed tank or container is essential to protect diesel fuel from damage and contamination. A well-built system serves as a defence mechanism against accelerated fuel aging and other fuel quality issues associated with poor construction. It is recommended to use portable tanks approved by the Department of Transportation (DOT), Underwriter Laboratory (UL), or Factory Mutual (FM). Additionally, ensure that the tank is clean and free from any pollutants or buildup that could contaminate the fuel. Regularly clean the tank to maintain its optimal condition.

To avoid water contamination, it is imperative to keep the diesel fuel dry during storage. Store the fuel in a cool, dry place, away from direct sunlight and heat sources such as furnaces, water heaters, and space heaters. Maintaining a temperature of less than 20 degrees Celsius can slow down the degradation process and extend the lifespan of the diesel fuel. Keep the fuel in airtight containers to prevent evaporation and moisture accumulation.

Another way to prevent water contamination is by using fuel additives and biocides. Biobor JF, for example, can be used to kill microbial contamination and preserve the fuel during long-term storage. Multifunctional fuel additives like Biobor DC or Biobor MD can also be used to stabilize the fuel, improve cetane, add lubricity, detergency, and disperse water. Additionally, fuel biocides are chemical additives specifically designed to control and prevent microbial contamination in diesel fuel.

Proper maintenance of equipment and vehicles is also essential in avoiding water and other contaminants. Regularly replace worn-out parts and filters, perform fuel filter changes, and use high-quality lubricants. If you notice any unusual odours or leaks from your tank, address these issues promptly to prevent contamination and damage to the diesel fuel.

Use approved containers

Diesel fuel is a highly stable and powerful energy source, but it requires careful storage to maintain its quality and performance. One of the most important considerations is the use of approved containers.

When storing diesel fuel, it is crucial to select containers that meet industry standards and regulations. The Department of Transportation (DOT), Underwriter Laboratory (UL), and Factory Mutual (FM) are among the organisations that approve containers for diesel storage. These approved containers are designed to safely hold diesel fuel and prevent leaks and spills. They often feature robust welded steel construction, as in the case of safety cabinets, which provide maximum protection in the event of a fire.

The choice between portable tanks and cabinets depends on the specific needs of the facility. Safety cabinets, for instance, are stationary storage solutions that can hold up to 60 gallons of flammable liquid per cabinet, with a maximum of three cabinets per facility, according to OSHA regulations. Portable tanks, on the other hand, offer flexibility and are ideal for construction or transportation needs.

To facilitate identification, approved containers for diesel fuel are often coloured yellow. This colour coding helps users quickly distinguish diesel fuel from other liquids in industrial and commercial settings. Additionally, some containers have two openings: one for filling and the other for dispensing, providing a safer and more controlled pouring experience.

Approved containers are just one aspect of safe diesel fuel storage. It is also important to maintain optimal storage conditions, keep the containers clean and free from contaminants, and regularly monitor the fuel for any signs of degradation. By following these guidelines, users can effectively preserve their diesel fuel and maintain its performance over time.
