Choose a well-constructed tank or container

When storing diesel fuel, it is imperative to use a well-constructed tank or container. This is crucial to prevent fuel degradation and other quality issues associated with a poorly constructed system. Here are some key considerations when choosing a suitable tank or container for storing diesel fuel:

Material and Construction

Select a tank or container made from durable materials such as steel, aluminium, or polyethylene. These materials offer superior resistance to chemical corrosion and maximise the longevity of your tank. Additionally, look for a tank with a protective finish, such as a powder-coated finish, to enhance its durability and chemical resistance.

Safety Features

Ensure that your chosen tank or container has safety features to minimise the risk of fire and spillage. For example, Eagle's Type I safety cans feature a seamless quality construction and flame arresters designed to offer flashback protection. They also have a spring-closing lid and a gasket that enables automatic venting at five psi of internal pressure. Type II safety cans offer similar features with the added convenience of an actuated pouring valve for controlled pouring.

Size and Capacity

Consider the size and capacity of the tank or container. Choose a size that suits your fuel consumption rate to avoid storing diesel for extended periods. Additionally, ensure that the tank is not too large, as diesel should generally be consumed or replaced within its storage life, typically between 6 to 12 months for average conditions.

Accessibility and Maintenance

Opt for a tank or container with features that facilitate easy access for filling and maintenance. For instance, consider a container with a funnel to prevent spills during filling or a cabinet with self-latching doors that secure contents and provide maximum protection. Additionally, look for a tank that is easy to clean and maintain, as regular cleaning is essential to prevent contamination and maintain fuel quality.

Compliance and Regulations

Ensure that your chosen tank or container complies with regulations and safety standards. For example, according to OSHA regulations, no more than 60 gallons of a flammable liquid may be stored in a single safety cabinet. Additionally, consider the NFPA's classification of diesel as a Class II combustible liquid due to its flashpoint, and choose a tank or container that meets these safety requirements.

By carefully considering these factors, you can choose a well-constructed tank or container that ensures the safe and effective storage of diesel fuel.

Store in a cool, dry place

Diesel fuel has a limited shelf life and can degrade over time, so it's important to store it correctly. If stored improperly, diesel can potentially ignite and threaten the safety of people and assets. Therefore, it is imperative to store and handle diesel fuel using approved containers and equipment.

When storing diesel fuel, it is important to keep it in a cool, dry place. The ideal temperature range for storing diesel is between 32° Fahrenheit and 95° Fahrenheit. Storing diesel at temperatures below or above this range will cause the fuel to degrade at an accelerated rate. To protect the fuel from extreme temperatures, you can store it in a shaded area and cover it with a tarp or store it underground. Underground storage can help insulate the fuel from temperature-related issues and keep it cooler.

In addition to temperature control, it is crucial to keep the fuel dry and free from contaminants. Contamination can occur when diesel fuel is exposed to oxygen, moisture, or other contaminants. To prevent this, use a well-constructed tank or fuel container that keeps the fuel dry and protected from the elements. The tank should be made of durable materials such as steel, aluminium, or polyethylene and should have a tight-fitting lid or cap to prevent spills and minimise the risk of fire.

To further ensure the quality of the diesel fuel, it is recommended to use additives and biocides. Biocides can help prevent the growth of bacteria and fungi, while additives such as Biobor Fuel Additives can preserve the fuel and reduce maintenance costs. Regular cleaning and maintenance of the tank are also important. It is suggested to clean the tank every ten years to maintain the life of the diesel fuel and the tank.

Understand the fuel type

Diesel fuel is a petroleum-based fuel with a limited shelf life. Over time, diesel can degrade and lose its effectiveness, potentially damaging fuel systems. The shelf life depends on factors like temperature, quality, and contamination. Diesel can be stored for up to a year without significant degradation if kept in a clean, dry, and cool environment.

Diesel has a flashpoint between 100-140°F (38-60°C), classifying it as a flammable liquid. It should be stored in approved containers, cabinets, and handling equipment to minimise fire risks. The storage area should be covered and sheltered from extreme weather.

The type of diesel fuel is also important. Most diesel today contains at least 5% biodiesel, which has storage limitations. Biodiesel blends have shorter shelf lives and are less stable, more sensitive to temperature and oxygen exposure, and more challenging to treat for issues.

To maintain fuel quality, use biocides to prevent bacterial and fungal growth. Prevent or eliminate biofilm, a sludge-like mass that can reduce biocide effectiveness and encourage re-infection. Additives like Biobor can preserve fuel and reduce maintenance costs by killing microbial contamination.

Use fuel additives

When storing diesel at home, using fuel additives can help to preserve your fuel and maintain engine performance. Here are some tips and suggestions for using fuel additives:

Firstly, it is important to understand the type of diesel fuel you are using and its storage requirements. Most diesel fuel today contains at least 5% biodiesel, which has different storage limitations compared to conventional diesel. Biodiesel and biodiesel blends tend to have a shorter shelf life, are more sensitive to temperature and oxygen exposure, and may require specific knowledge to address issues that arise.

To preserve your fuel and reduce maintenance costs, consider using fuel additives such as Biobor. Biobor JF, for example, can help kill microbial contamination and preserve the fuel during long-term storage. Multifunctional fuel additives like Biobor DC or Biobor MD can stabilize the fuel, improve cetane, add lubricity, detergency, and disperse water. These additives can be particularly beneficial for biodiesel blends, improving their stability and extending their shelf life.

When purchasing fuel additives, consider the storage and handling requirements of the additive itself. Some additives may have an unpleasant smell or require specific containers for safe storage. Using gloves and sealed containers can help with handling and storage. Additionally, some additives come in refillable bottles or jugs, making it convenient to store and use them without creating a mess.

While some people regularly use fuel additives with each tank of diesel, others believe that additives are unnecessary and do not provide a significant return on investment. It is essential to weigh the potential benefits against the cost and your specific use case. For example, if you live in a cold climate, using a cold-weather treatment additive may be beneficial to improve the performance of your diesel engine during winter.

Finally, when using fuel additives, it is crucial to follow the instructions and recommendations provided by the manufacturer. This includes knowing the appropriate dosage, frequency of use, and any specific storage or handling requirements for the additive. By using fuel additives correctly and choosing the right type for your diesel fuel, you can help maintain fuel quality and engine performance while storing diesel fuel at home.
