How Long Is Heating Oil Good For?

Written on: March 14, 2022

Does it ever expire?

heating oil delivery massachusettsAlmost everything has an expiration date. From the food in your fridge to the gas in your car, nothing lasts forever (except maybe for honey and diamonds). So how about heating oil? Does it go bad? You’ve probably been using heating oil in large amounts this winter, but what about as the weather gets warmer and you start using it less? How much do you have to worry about the oil in your New England home’s tank going bad?

The short answer is most people don’t have to worry about their heating oil going bad. Number 2 heating oil (the type used in most US homes) has a shelf life of about 1 ½ to 2 years.

And quite honestly, even if the heating oil in your tank is nearing the two-year mark, chances are you can still use it. Old heating oil doesn’t spoil like old milk does. It simply becomes less potent. In short, you won’t get as much energy from it. Said another way, it won’t produce as much heat when it’s burned.

However, there is a limit. And your furnace will shut off automatically if the heating oil isn’t reaching the minimum temperature range for your furnace when it’s burned. And if that happens, you’ll need to have your furnace serviced. So if it’s been two years or more or there’s a chance the heating oil in your tank is no longer still good, your best bet is to have your tank professionally drained and refilled.

Other Factors In Heating Oil’s Shelf Life

The 1 ½ to 2 years is just a general guideline for the shelf life of your heating oil. There are other factors that can affect the length of time your heating oil will remain viable. For example:
