What You'll Learn
Containers approved by the Department of Transportation
Diesel fuel should be stored in containers that are approved by the Department of Transportation. These containers should be well-constructed and keep the fuel dry. Metal and plastic containers, safety cans, fibre drums, and intermediate bulk containers are all approved by the Department of Transportation for storing diesel fuel. These containers must meet specific regulations and guidelines for emergency venting and maximum container sizes.
It is important to store diesel fuel safely to maintain its quality and prolong its life. Diesel fuel should be stored away from direct sunlight and extreme temperatures to reduce accelerated fuel degradation and condensation. The storage area should be free from potential heat sources, including heaters and furnaces, and anything flammable.
Additionally, it is recommended to establish a monitoring and maintenance plan for your diesel fuel storage system. This includes regular inspections of the fuel system and fuel quality to identify any issues that may impact the performance of your equipment. If fuel is stored for more than 30 days, a fuel stabilizer should be added to prevent microbial growth and compound contamination.
To further maintain the quality of diesel fuel, biocides can be used to prevent the growth of bacteria and fungi, and steps should be taken to prevent or eliminate biofilm, a sludge-like mass that can form at the diesel-water interface. By following these guidelines and using approved containers, diesel fuel can be safely stored and maintained for an extended period.

Keeping fuel dry and cool
Keeping diesel fuel dry is critical to its longevity. Water in the fuel can cause significant engine damage. Water can enter the tank in several ways, including through air intake, and it can be challenging to remove once it has entered the fuel system. Basic, old engines can handle a bit of water, but new, high-tech engines cannot. Therefore, it is essential to carefully filter out any water that may be present in the fuel. Additionally, water creates an environment conducive to microbial growth, which can lead to sludge and biofilm formation, further compromising fuel quality.
To keep diesel fuel dry, it is essential to choose a well-constructed storage tank or container that can protect the fuel from moisture ingress. It is also important to keep the tank full during long-term storage, as this helps to reduce condensation, a common problem when fuel levels are low. Regularly inspecting the fuel system and addressing any issues is also crucial to maintaining fuel quality.
Another critical aspect of storing diesel fuel is keeping it cool. Diesel fuel can be stored within a wide range of temperatures, but extreme temperatures can negatively impact its longevity. Storing diesel fuel at less than 32° Fahrenheit or above 95° Fahrenheit will cause the fuel to degrade at an accelerated rate. Therefore, it is recommended to store diesel fuel at room temperature and in a well-ventilated area, away from any potential heat sources and direct sunlight.
Additionally, underground storage can help insulate the fuel from temperature-related issues. Keeping the fuel cool also slows down the oxidation process, a chemical reaction that occurs when diesel fuel is exposed to oxygen, resulting in the formation of unwanted gum, sludge, and sediment. To further extend the life of diesel fuel, fuel stabilizers can be added, especially if the storage period exceeds 30 days.

Avoiding direct sunlight
Diesel fuel should be stored away from direct sunlight to reduce accelerated fuel degradation. The more heat, the less stable your fuel becomes. Ultraviolet (UV) radiation from the sun can break down the chemical bonds in diesel fuel, causing it to lose its effectiveness and potentially damaging your engine.
Exposure to sunlight is one of the most significant contributors to fuel degradation. This is due to the UV radiation from the sun, which breaks down the chemical bonds in diesel fuel. This causes the fuel to become less effective and can even damage your engine. Additionally, temperature fluctuations that occur when fuel is exposed to sunlight can cause fuel stability issues, leading to the formation of unwanted deposits and harmful particles that can further damage your engine.
By storing diesel fuel in a cool, dry place away from direct sunlight, you can maintain fuel stability and protect your fuel from the harmful effects of sunlight and temperature fluctuations. This will prevent the formation of unwanted deposits and particles, ensuring your fuel remains clean and efficient.
When choosing a spot for your diesel fuel storage, consider factors such as temperature, humidity, and sunlight exposure. The ideal storage location is a cool, dry place with minimal exposure to direct sunlight. This will help protect your fuel from the damaging effects of UV radiation and temperature fluctuations.
Consider covered storage areas, sheltered from extreme weather, or underground storage, which can insulate the fuel from temperature-related issues.

Using fuel stabilizers and anti-fungals
Diesel fuel is a perishable commodity and can degrade over time. To prevent this, fuel stabilizers can be used to extend the lifespan of stored diesel fuel. Fuel stabilizers are chemical additives designed to maintain the quality and chemical properties of diesel fuel. They prevent degradation caused by exposure to air, moisture, temperature changes, and extended storage periods.
Fuel stabilizers are typically made up of assorted chemical compounds, including antioxidants, corrosion inhibitors, and detergents. These components work together to prevent fuel degradation and maintain fuel quality. By inhibiting the chemical reactions that lead to degradation, fuel stabilizers can prevent oxidation and the subsequent formation of acids, sediments, gums, and varnishes. This helps to avoid clogged fuel filters and injectors, which can hinder engine performance.
Additionally, fuel stabilizers can help prevent microbial growth. Microbes thrive at the water-diesel interface, and once present, they multiply quickly and are challenging to eliminate. Fuel stabilizers work by removing water from the fuel, creating an environment that is unfavourable for microbial growth.
When using a fuel stabilizer, it is recommended to add it to fresh fuel to allow for proper mixing. The optimal time to add a fuel stabilizer is when fueling up, especially if the vehicle or equipment will be stored for extended periods. It is important to follow the directions on the bottle for the required amount of stabilizer based on the volume of fuel.
Some popular diesel fuel stabilizers on the market include STA-BIL Diesel Fuel Stabilizer and Howes Meaner Power Kleaner. These products are designed to keep diesel fuel fresh, improve engine performance, and protect the fuel system.

Maintenance and monitoring plans
Container and Location
Choose a well-constructed, approved container or tank that is the appropriate size for your fuel quantity. The container should be made of a material that prevents fuel degradation and contamination. Ensure the storage area is safe, dry, and well-ventilated, maintaining a temperature below 70 degrees Fahrenheit. Keep the fuel away from direct sunlight, heat sources, and anything flammable.
Fuel Quality and Additives
Regularly inspect your fuel for any changes in quality, such as the presence of water, sludge, or microbial growth. Use biocides to prevent bacterial and fungal growth, and break down any biofilms that may reduce the effectiveness of biocides. Consider using fuel stabilizers, especially if your fuel has been stored for over 30 days, to prevent microbial growth and compound contamination.
Tank Maintenance
Keep your tank clean and well-maintained. Drain and scrub the tank every other year, and always filter the fuel when removing it from the tank to prevent contamination. Ensure that you meet federal, state, and local standards and regulations regarding fuel storage, including leak prevention and corrosion protection.
Fuel Rotation and Usage
Establish a timeframe to use up old fuel and replace it with fresh diesel. This is especially important for standby or emergency generators, as fuel sources can be overlooked in testing and maintenance. If your fuel has been stored long-term, consider mixing it with fresh diesel or using additives like Diesel 911 cetane boost to improve its quality.
Monitoring Schedule
Create a monitoring schedule to regularly check your fuel quality and tank condition. This should include visual inspections and, if necessary, laboratory tests to identify any issues early on. Regular system inspections can reduce maintenance costs and fuel waste by identifying and fixing problems promptly.
