Your Tank Gauge

Get familiar with your Tank Gauge

When it comes to our customers, we have a pretty good idea of how much fuel is in their tank. It’s based on a series of calculations and basic knowledge of your home, all of which are outlined on our How does automatic delivery work page. Whether you’re an automatic delivery customer or a will-call customer, the oil tank in your home has a gauge on it. We would like to help you know how to read your tank gauge and how much fuel is in your tank based on where the gauge is.

There are several different types of gauges that are install in tanks, one of the most popular and difficult is a bobber type gauge. This a long glass tube with lines for full, ¾, ½, ¼, and measurements in between. Inside the tube is a bobber that represents where how much oil is in the tank, similar to the image above. Many of customers will call and state that the tank is empty when the bottom of the bobber hits E. The bobber is meant to be read from the top down. So if the top of the bobber is at ¼ you have enough oil for several days in the winter, but should schedule a delivery or a delivery will be on it’s way. Other gauges include dials and old time outside thermometer styles which can be easier to read off.

Now, what does a ¼ tank mean? Using the image below you’ll know how much fuel is in your tank at any given moment. Now, these numbers are based on a standard 275 oil tank. When the tank is full will only have about 255 gallons in it instead of a full 275. This is because of air inside the tank that prevents it from being maxed out. When a driver makes a delivery they listen for a whistle that comes from the vent pipe (one of the two pipes that run out of your tank). This whistle means that the tank is full.
