Diesel Storage

How Long Can You Store Diesel Fuel For?

If you ask different people this question, you will likely get different answers. That's because the storage life of any fuel is dependent on the conditions. The military has an obvious interest in fuel storage, given what they do, so they've studied storage life of fuels pretty closely over the years. The key is keeping the fuel cool and keeping the fuel dry. Under ideal conditions, diesel fuel can be stored between six and twelve months. To extend the life past twelve months, even under the best conditions, it needs to be treated with fuel stabilizers and biocides. If the fuel can't be kept cool, below 70 degrees F consistently, twelve months is the longest reasonable estimate for storage. Keep in mind that this is for diesel fuel, not ethanol blends or biodiesel blends.
