Heating Oil: How Long Does It Last?

Will heating oil “go bad” if I fill my tank in the summer?

During the summer, you’re probably focusing on sun and fun, not winter’s chills.

But, you should take a little time to do exactly that – it’ll save you some hassle and money in the long run! For instance: Did you know filling your heating oil tank now, in the summer, helps protect your heating oil tank? It’s true! Not to mention filling up now means you’ll beat the ever-consistent fall rush.

Some customers express concern about their fuel sitting idle for months at a time, but we assure you, you don’t have to worry about the heating oil “going bad” between now and when you turn on your furnace or boiler this fall.

The shelf life for heating oil is between 18 and 24 months. So even the remaining heating oil in your tank from last winter is still good!

The key point here is that filling your tank now is a very good idea. Let’s run through exactly why at a bit greater depth:

Condensation: Your heating oil tank’s worst enemy

Condensation begins to develop on the bare interior walls of the tank when you don’t have a full tank. This condensation develops faster when temperatures are warmer, like they are now in the summer.

Condensation is extremely bad for your oil tank in several ways.

Gravity is another problem with condensation. When condensation builds up, it drips off of the interior tank wall. Because condensation is heavier than heating oil, it will sink to the bottom of the tank. Once there, the condensation begins to make a perfect breeding ground for sediment. Sediment leads to corrosion of your heating oil tank from the inside out.

If the corrosion causes a tank failure, you not only have to replace your heating oil tank, but you have to bring in a professional to safely remove your failed tank, as well as cleaning up spilled oil to regulatory standards. That can cost you far more than you’d like to pay at any point in time.

A full tank is a protected tank

Keeping your heating oil tank full will prevent the development of condensation through the summer.

Another benefit is that you’ll have a full tank of heating oil when heating season returns. If there’s a cold snap early, which often happens here in the Hudson Valley, you’ll have plenty of heating oil to keep your home warm and you won’t have to worry about the hassle and expense of an emergency heating oil delivery.

You can also save money by filling your heating oil tank now: Heating oil prices have only just slightly raised from historically lower levels. There’s still time to take advantage of low prices – and great payment plan options we offer as well!
