If your furnace or boiler runs on oil, it’s important to monitor the tank’s gauge closely. Once the fuel gets low, you’ll need to arrange for prompt oil delivery so that your home never runs out of heat. Here’s what to know.

How Do You Read the Oil Tank’s Gauge?

The gauge is a glass or plastic cylinder that houses a white float and a thin arrow and is usually located near the top of the tank. You should see markings similar to those on the gas gauge in your vehicle lining the edge of the float. They might be specific numbers, which correspond to the actual number of gallons left in the tank, or they might simply read: F, 3/4, 1/2, and 1/4.

If the tank is full, the arrow will point to the highest number or the F. If, on the other hand, there’s only one-quarter of the oil left, the arrow will point to the 1/4 or to the number that corresponds to 25% of the tank’s capacity. If the arrow has sunk below this marker, the tank is nearing empty, and you need to schedule oil delivery as soon as possible. 

How Long Will the Oil in the Tank Last?

The rate at which your home uses up the oil will depend on several factors, including the square footage of the property, the age and efficiency of the heating system, and the airtightness of the structure. On average, a 2,500-square-foot house will use between 6 and 7 gallons over a 24-hour period when the outside temperature is about 32 degrees Fahrenheit.
