According to the U.S. Energy Information Administration (EIA), 5.5 million U.S. households used home heating oil as their primary heating fuel in 2018. If your home is one of them, it’s important to know how to properly store the oil, especially if you buy it in bulk. Here’s what you should know.

A Guide to Home Heating Oil Storage

How long does home heating oil last?

No. 2 grade heating oil, which is the most common type used, usually lasts between 18 and 24 months inside a residential oil tank. This is assuming that the tank is clean and free of impurities and that the oil is treated with the right additives. 

What are additives and how do they help?

A reputable heating oil supplier will recommend appropriate additives and put them in your supply when they fill up the tank. These additives stabilize the oil and extend its shelf life by slowing down the breeding of bacteria.

What makes home heating oil go bad?

Over time, oil breaks down naturally due to bacteria within the fuel. However, the oil will degrade at a much faster rate if it comes in contact with impurities.

Contaminants such as rust, metal, sludge, and water can affect the oil’s viscosity and make it difficult for it to work its way through your heating system. Oil that’s stored in a clean and well-maintained tank will last significantly longer. 

Can you fix home heating oil once it’s gone bad?

The bacteria that forms over time from the oil’s acids and moisture destroys the fuel’s combustible traits. Once the oil has deteriorated in this fashion, it can’t be fixed. Unfortunately, additives won’t be able to restore it, and you’ll have to replace it with new fuel.
