Education: Your Oil Tank Gauge

Oil Tank

Understanding your Oil Storage Tank and Tank Gauge

A closer look at your oil tank

How do you know when you should order your next oil delivery? How much fuel is actually in my tank when the gauge says 1/8? These are a few of the questions that we receive and we'll try to answer these and more below.

A closer look at your oil tank

In most cases, you will find that you have an oil storage tank that will hold 275 gallons of oil. A traditional fill of the tank will usually include 245 gallons, this accounts for air and debris on the bottom of the tank. When a Glow driver fills your tank they will hear a whistle sound, once the whistle stops the driver must turn off the pump. This indicates that the tank is full and pumping should be stopped immediately.

A closer look at your tank gauge

Next is the gauge, most common is a gauge similar to the one below to the left, however they can also look like the gauge to the right.

The most common oil tank gauge that represents how much oil is left in the tank

An alternate oil tank gauge that represents how much oil is left in the tank

The gauge represents how much fuel is left in the tank, a general rule of thumb is to never let the gauge get below 1/4. If you run out of Oil in your tank before more fuel is delivered your boiler or furnace will need to primed, this is an additional service that carries a fee. The best practice to avoid this fee is to order fuel when the gauge gets to 1/4. While we offer next day delivery, depending on your fuel usage and the accuracy of your gauge you could run out of fuel on extremely cold winter nights with 1/8th of a tank.

How much oil is actually in my tank when the gauge says 1/2? How long will that last?

To the right is a handy chart that will help you keep track of how much fuel is in your tank based on the reading of the gauge. How long will a 1/2 tank of oil last? That depends on the efficiency of your boiler or furnace, size of your home, water heater use, and the temperature of your home.
