Whether you need diesel for your farm equipment or to power up your fleet of buses, it can be helpful to have a large amount on hand. Purchasing the fuel in bulk allows you to save on costs; however, it’s imperative to know how to store it and how long it lasts before purchasing large amounts. Below is a guide to everything you need to know about storing the fuel. 

Understanding Diesel Storage

How Long Can It Be Stored For?

If stored properly, it should last up to one year. Make sure to keep the diesel cool—below 70 degrees Fahrenheit—and in a dry place, avoiding moisture buildup and direct sunlight exposure. 

Where Do You Store It?

Diesel is housed in specialized storage tanks that can be above or partially below ground. If you have a facility on your property, it will be subject to standard EPA regulations that govern leak prevention and corrosion avoidance. When storing your diesel, it’s important to keep the tank as full as possible. That empty space allows for both condensation and bacteria, putting your diesel at risk. Another maintenance practice is to add biocides and fuel stabilizers. Biocides will destroy any thriving bacteria, and fuel stabilizers eliminate unwanted oxidization. 

When Should You Dispose of It?

If you still have unused diesel that was acquired over a year ago, it’s best to have your supplier visit and assess its condition. Adding spoiled diesel to your engines can cause significant damage that will require repairs or even replacement. The most common signs of spoilage are when the diesel develops gummy, gel-like substances and appears to resemble a sludge. It will become darker than normal, and may even start to smell bad due to all the microbes that have proliferated.
