How To Locate and Read An Oil Tank Gauge

HOW TO READ AN OIL TANK GAUGE

Chances are your oil tank is in the basement or outside somewhere close to the house. It’s a big metal tank.

HOW TO READ AN OIL TANK GAUGE

Sticking up on top of the oil tank is a clear tube with a float inside. On the outside, it is marked: F, ¾, ½, ¼, (from top to bottom).Those numbers tell you how much of the tank is full. The float goes up and down according to how much fuel is in the tank. So, if the float is aligned with the ½ mark, the tank is half full. If the float is at the bottom of the tube or not visible, then the tank is empty or close to empty.

HOW MUCH OIL IS LEFT IN MY TANK?

A standard residential oil tank holds 275 gallons. Based on that size, the following readings indicate that your tank contains approximately this many gallons:

  • 1/8 = 40 gals
  • 1/4 = 70 gals
  • 3/8 = 100 gals
  • 1/2 = 130 gals
  • 5/8 = 160 gals
  • 3/4 = 200 gals
  • 7/8 = 240 gals
  • “full” = 265 gals

HOW TO CALCULATE HOW MUCH OIL IS IN YOUR TANK

Most houses have a 275-gallon tank. When full that tank holds close to 225 gallons. If the gauge reads ½ you have about 110 gallons of fuel. At ¼ you have about 55 gallons and at ¾ about 170 gallons. It is recommended to call for a refill when you're around the 1/2 and 1/4 mark in the clear tube.

HOW MUCH OIL DO YOU NEED TO FUEL YOUR HOME?

At an outside air temperature of 32° (average over a 24-hour period) the typical 2500 sq.ft house will burn about 6.5 gallons per day. So if you have half a tank (110 gallons) and it’s cold out you’ll use up that fuel in about 17 days. If you’re not on automatic delivery you need to give us 5-days’ notice so you wouldn’t want to wait more than about 10 days to call for a delivery.
