Diesel fuel is a critical resource for many applications, from powering vehicles to running generators. Proper storage is essential to ensure that diesel remains usable over time. This article will explore how long you can keep diesel in a jerry can, providing a comprehensive guide to storage practices, factors affecting fuel longevity, and tips to maintain fuel quality.
Understanding Diesel Fuel
Diesel fuel is a type of petroleum-based fuel used in diesel engines. It is known for its energy density and efficiency. Diesel is used in various applications, including cars, trucks, generators, and machinery. The longevity of diesel fuel in storage depends on several factors, including the type of diesel, storage conditions, and the quality of the jerry can.
Types of Diesel Fuel
Regular Diesel: This is the most common type, used in most diesel engines. It has a standard shelf life if stored properly.
Premium Diesel: This type contains additives to improve performance and reduce emissions. It may have a slightly longer shelf life due to its enhanced formulation.
Bio-Diesel: Made from renewable sources, biodiesel can have different storage requirements compared to regular diesel.
Factors Affecting Diesel Longevity
Several factors influence how long diesel can be stored in a jerry can:
Storage Temperature: Diesel fuel is best stored in a cool, dry place. High temperatures can accelerate the degradation of diesel.
Exposure to Air: Diesel exposed to air can oxidize, leading to the formation of sludge and gums that can clog engines and fuel systems.
Contamination: Dirt, water, and other contaminants can compromise the quality of diesel fuel.
Type of Jerry Can: The material and seal of the jerry can play a significant role in maintaining diesel quality.
Shelf Life of Diesel Fuel
Diesel fuel generally has a shelf life of about 6 to 12 months when stored under ideal conditions. However, this can vary depending on the type of diesel and storage conditions. Here’s a more detailed breakdown:
Regular Diesel: Typically, regular diesel can last between 6 to 12 months if stored in a proper jerry can and kept in a cool, dry environment.
Premium Diesel: Premium diesel, with its additives, may last slightly longer, up to 12 months or even a bit more.
Bio-Diesel: Biodiesel has a shorter shelf life, usually around 6 months, due to its tendency to oxidize more quickly.

Best Practices for Storing Diesel Fuel
To maximize the shelf life of diesel fuel, follow these best practices:
Use Quality Jerry Cans: Ensure that the jerry can is made of high-quality, corrosion-resistant material. Plastic jerry cans should be UV-resistant and properly sealed to prevent leaks and contamination.
Store in a Cool, Dry Place: Keep diesel in a shaded, cool area away from direct sunlight and heat sources.
Seal Tightly: Ensure that the jerry can is tightly sealed to minimize air exposure, which can lead to oxidation.
Avoid Contamination: Store diesel in a clean container to prevent the introduction of dirt and water.
Use Fuel Stabilizers: Additives or fuel stabilizers can help extend the life of diesel fuel by preventing oxidation and degradation.
Signs of Diesel Fuel Degradation
Over time, diesel fuel can degrade. Here are some signs that your diesel fuel may be past its prime:
Change in Color: Fresh diesel is usually clear or slightly yellow. Darkening can indicate oxidation.
Presence of Sediment: Sediment or sludge at the bottom of the jerry can is a sign of fuel degradation.
Strange Odor: Diesel fuel that smells sour or has an unusual odor may be spoiled.
Poor Engine Performance: If the engine struggles to start or runs poorly, degraded fuel could be the cause.
Testing Diesel Fuel Quality
If you suspect that your diesel fuel has degraded, you can test it for quality:
Visual Inspection: Check the color and clarity of the fuel.
Smell Test: Look for any off-putting odors.
Sediment Check: Observe if there is any sediment or sludge in the fuel.
How to Dispose of Old Diesel Fuel
If your diesel fuel has gone bad, it is important to dispose of it properly:
Check Local Regulations: Different areas have different regulations for disposing of hazardous materials like diesel fuel.
Contact a Disposal Service: Use a certified disposal service to handle the fuel safely and in an environmentally friendly manner.
Tips for Extending Diesel Shelf Life
Regular Monitoring: Check the condition of your stored diesel periodically.
Use Within Recommended Time Frame: Try to use diesel fuel within the recommended storage period to avoid issues.
Keep Records: Maintain records of when you purchased and stored the diesel to track its age and usage.
Conclusion
Proper storage of diesel fuel in a jerry can can significantly impact its longevity and usability. By following the best practices outlined in this article, you can extend the shelf life of your diesel and ensure it remains in good condition. Remember to monitor the fuel regularly, use quality storage containers, and be mindful of storage conditions to keep your diesel fuel in optimal shape.
FAQs
Can you use 20-year-old diesel?
Using 20-year-old diesel is generally not recommended. Diesel fuel degrades over time, especially if it is not stored under ideal conditions. After 20 years, diesel would likely have significant contamination, oxidation, and microbial growth, making it unsuitable for use in engines. This can lead to clogged filters, injectors, and potential engine damage.
Is it safe to store diesel in a jerry can?
Yes, it is safe to store diesel in a jerry can if the can is of high quality and designed for fuel storage. Ensure that the jerry can is made of a material resistant to corrosion, typically metal or high-density polyethylene (HDPE). The can should be properly sealed to prevent contamination and evaporation. Store the jerry can in a cool, dry place, away from direct sunlight and heat sources, to maintain the diesel’s quality.
How long can diesel sit in a gas can?
Diesel can sit in a gas can for 6 to 12 months under ideal conditions. Factors such as temperature, exposure to air, and contamination will affect the shelf life. Using fuel stabilizers can help extend the storage life. Regularly check the fuel for signs of degradation, such as changes in color, odor, or the presence of sediment.
How long before diesel goes bad?
Diesel fuel typically goes bad within 6 to 12 months if stored under standard conditions. Factors such as temperature fluctuations, exposure to air, and contamination can accelerate the degradation process. Using high-quality storage containers, keeping them sealed tightly, and adding fuel stabilizers can help extend the diesel’s usable life. Signs of bad diesel include darkening of color, foul odor, and the presence of sludge or sediment.
