Heating Oil Has a Long “Shelf Life”

heating oil expiration massachusetts If you ended the season with plenty of heating oil in your tank, you may be wondering if your fuel oil will still be good when you turn on your heating oil boiler or heating oil furnace in the fall again.

No worries. Your heating oil will be fine. That’s because the average life span of home heating oil ranges between 18 and 24 months.

However, if you ended winter with a near-empty tank (a quarter full or less), you should get a fill-up as soon as possible. Here’s why.

A lot of empty space inside your heating oil tank causes trouble. It’s best to keep your storage tank at least half-full (preferably more) during the warm months.

Condensation is the reason for the trouble. Empty space in your tank is space where water condensation can form. Condensation is more common during the summer. Hot, humid days and cool nights create the perfect atmosphere for condensation buildup to accelerate inside your tank. And if your tank is aboveground, outdoors and in an unshaded area, it’s especially prone to condensation.

The Problems Caused by Oil Tank Condensation

After water forms on the bare walls on the empty area of the tank, it drips down and sinks to the bottom of the tank because it is denser than heating oil. There, it becomes an ideal environment for bacteria and other microorganisms. Over time, these become sediment that can create problems with your oil tank. One problem is that sediment, also known as sludge, can get into your fuel lines and clog them up. This will cause your heating oil system to shut down.

Keeping your heating oil tank full during the summer months prolongs its life. That’s because the same condensation that results in sludge can also corrode your tank from the inside out – a big problem that could be difficult to see coming and costly to remediate.
