There is no precise answer to this question, as it will vary wildly depending on the size of your fuel oil tank, the size of your home, the temperatures outside, the energy efficiency of your home and how warm you keep the temperature. Freezing temperatures outside or fluctuating temperatures can lead to using more oil than you typically would. It’s always better to be on the cautious side and order more heating oil during periods of intense cold or when there is a snowstorm coming.
