Does Heating Oil Stay “Fresh” For A Long Time?

old heating oil vermontIt’s of utmost importance to keep your heating oil tank at least half full, even in the offseason (if your tank is near empty, now is the perfect time for a heating oil delivery!) And if you follow that advice, your heating oil will likely sit idle in the tank for at least four or five months while you wait for temperatures to drop again here in the Central Vermont.

The question is, will using heating oil that isn’t “fresh” harm your heating equipment?

The short answer is no. No. 2 heating oil has a typical shelf life of just under two years—a wide enough window to cover heating oil you purchased during the previous heating season.

If your heating oil is getting close to that age, say, for example, if you own a vacation or second home that you don’t use every year, or use only during the summer, you can still use the heating oil, although it probably won’t produce as much heat as “fresh” oil.

If the oil is so old that it can’t burn hot enough to reach your furnace’s minimum temperature range, your furnace will automatically shut off; if that happens, you will need to hire a professional to restart your system. If you know for certain that oil has been sitting in your tank for more than two years, it’s probably better to have your tank professionally drained and refilled.

Other Factors With Heating Oil Aging

Of course, it’s important to keep in mind is that two years is simply an average shelf life for No. 2 heating oil. Several factors can raise or lower that number, including:
