Diesel fuel is a crucial energy source used in various applications, from powering vehicles to machinery and even backup generators. However, storing diesel properly is essential for maintaining its quality and ensuring that it performs efficiently when needed. One common method for storing diesel is in a jerry can. But how long will diesel last in a jerry can? This article will examine this topic in detail, covering factors that affect diesel’s shelf life, how to store it properly, and what you can do to extend its lifespan.
Factors Affecting Diesel’s Shelf Life in a Jerry Can
Several factors contribute to the lifespan of diesel fuel in storage. These include environmental conditions, the quality of the fuel, the material of the storage container, and how well the diesel is sealed. Understanding these factors will help you determine how long diesel will last in a jerry can and how to maximize its effectiveness.
Environmental Conditions
The temperature and humidity in the environment where you store your diesel fuel play a significant role in how long it will last. Diesel stored in hot or humid conditions will degrade much faster than when kept in cooler, dry conditions. High temperatures can cause the fuel to oxidize more quickly, while moisture can lead to the formation of water in the diesel, which can promote bacterial growth and corrosion in the fuel system.
Ideally, diesel should be stored in a cool, dry place where temperatures are consistent. This helps to slow down oxidation and keeps contaminants from affecting the fuel. It is also recommended to avoid storing diesel fuel in direct sunlight or near heat sources, as these can hasten fuel degradation.
The Quality of Diesel Fuel
The quality of the diesel fuel you start with also impacts how long it will last in a jerry can. New diesel fuel, especially when purchased from a reputable supplier, will generally last longer than older fuel that has been sitting around for some time. Over time, diesel fuel can absorb moisture and develop microbial growth, particularly in storage conditions that are not optimal.
When purchasing diesel fuel for storage, it’s essential to ensure that the fuel is of high quality and free from contaminants. This means looking for clear, clean fuel without any visible particles, and ensuring that it’s stored in a manner that prevents the introduction of water or dirt. Using a fuel stabilizer can also help maintain the quality of the diesel for a longer period.
The Storage Container (Jerry Can)
The type of storage container you use for diesel fuel is crucial in determining how long the fuel will last. Jerry cans are commonly made from metal or plastic. Both materials have their pros and cons when it comes to fuel storage.
Metal Jerry Cans: Metal jerry cans, especially those made from high-quality steel, are often considered better for storing diesel because they provide a strong, durable container that can withstand rough handling and environmental conditions. However, metal containers can be prone to rusting if they’re exposed to moisture, which could affect the quality of the diesel inside.
Plastic Jerry Cans: Plastic jerry cans are lighter and resistant to rust, making them a popular choice. However, plastic containers can degrade over time, especially when exposed to sunlight or extreme temperatures. The plastic may become brittle and prone to cracking, which can allow air and moisture to enter, reducing the fuel’s shelf life.
To ensure that your diesel lasts as long as possible in a jerry can, it’s important to choose a high-quality container that is designed for fuel storage. Additionally, make sure the jerry can is tightly sealed to prevent air and moisture from getting inside.
Air Exposure and Fuel Sealing
One of the key factors in determining how long diesel will last in a jerry can is how well it is sealed. Exposure to air can cause the diesel to oxidize and degrade more quickly, which reduces its performance. Therefore, it’s essential to ensure that the jerry can is properly sealed after filling it with diesel.
When sealing the container, check for any cracks, gaps, or damaged seals. A tight seal will keep the air out, which is important in preventing contamination. Some people choose to use fuel stabilizers or additives that can further reduce the impact of air exposure by preventing the fuel from breaking down.
The Shelf Life of Diesel Fuel in a Jerry Can
The shelf life of diesel fuel stored in a jerry can is generally between 6 to 12 months, depending on the storage conditions and whether or not the fuel is treated with stabilizers. In optimal conditions, diesel fuel can last up to a year in a well-sealed, high-quality jerry can. However, this timeframe can vary significantly depending on the factors mentioned above.
Diesel Fuel Without Stabilizers
Without any additives or stabilizers, diesel fuel is more susceptible to degradation due to oxidation and the formation of contaminants. In this case, the fuel may begin to show signs of deterioration in as little as 6 months. The fuel will start to lose its combustibility, and may cause engine performance issues such as rough idling, starting problems, and reduced power.
Diesel Fuel with Stabilizers
When stored with a fuel stabilizer, diesel can last significantly longer—up to 12 months or even longer. Fuel stabilizers are additives that help slow down the oxidation process and reduce the formation of solids, gums, and other contaminants that can cause fuel problems. If you are storing diesel for an extended period, using a stabilizer can be an effective way to extend the shelf life and maintain fuel quality.
What Happens After Diesel Fuel Degrades?
As diesel fuel begins to degrade, several changes can occur that affect its performance. These include:
Oxidation: Over time, exposure to air causes diesel fuel to oxidize, leading to the formation of gums, varnishes, and other byproducts. This can clog fuel filters, injectors, and cause poor combustion, leading to engine issues.
Microbial Growth: Water contamination in stored diesel can lead to microbial growth, which can form sludge and other deposits that can damage the engine and fuel system.
Fuel Water Separation: When moisture accumulates in diesel fuel, it can lead to water separation. This is a problem because water in diesel can cause engine performance issues, corrosion in the fuel system, and potential engine failure.
To avoid these issues, it is essential to regularly inspect your stored diesel fuel and ensure that it remains free of contaminants.
Tips for Extending the Shelf Life of Diesel Fuel in a Jerry Can
There are several steps you can take to help your diesel fuel last as long as possible in a jerry can:
Store in a Cool, Dry Place: Keep the jerry can in a shaded, cool area away from direct sunlight and heat sources.
Seal Tightly: Ensure that the jerry can is tightly sealed to prevent air and moisture from entering.
Use Fuel Stabilizers: Add a fuel stabilizer to extend the life of your diesel.
Check for Water Contamination: Periodically check the diesel for water accumulation, which could lead to microbial growth or fuel separation.
Use High-Quality Containers: Choose high-quality jerry cans that are designed for fuel storage and are free from cracks or leaks.
Rotate Fuel: If you’re storing diesel for extended periods, make sure to use older fuel before replenishing with new fuel to keep the supply fresh.
Conclusion
Diesel fuel can last anywhere from 6 to 12 months in a jerry can under optimal storage conditions. However, factors such as temperature, humidity, and air exposure can affect its shelf life. To maximize the lifespan of your diesel fuel, it’s important to store it in a cool, dry place, use a high-quality, sealed container, and consider adding fuel stabilizers. By following these guidelines, you can ensure that your diesel remains in good condition for when you need it most.
