When to Refill Your Propane Tank

The Best Time to Get a Propane Tank Refill

Instead of waiting to run out of propane before refilling, we recommend filling your tank up when it has 2 pounds of fuel left. Not sure when to refill your propane tank? The answer is simpler than you might think. There are two main ways to check the fuel levels of a propane tank. 

  1. Look at the fuel gauge/overfill protection device located at the top of your tank. When the arrow of the gague points to the red zone, it means that the tank is due for a refill. 
  2. Weigh your tank on a scale and subtract the 'tare weight'.

Tare weight is the weight of the tank when empty and can be found on the upper right side of the tank collar or imprinted directly on the tank. The tare weight will be marked with the acronym TW. For example, TW-16.6lbs would mean that the weight of the propane cylinder when empty is 16.6lbs. If you weighed your tank at 18lbs and the tare weight was 16.6lbs, then you have 1.4lbs of fuel left.

20lb propane tanks are the most common cylinders, but U-Haul sells propane tanks up to 100lbs. Propane tanks may be made with either steel or aluminum. Information about what sort of tank you have can be found on the tank collar. 

It is also possible to use water to get a rough estimation of how much fuel you have left. Pour warm water down the side of your tank. The liquid propane within the tank will absorb the heat and cause your propane tank to feel cool to the touch where there is propane and warm where empty.

Save Money by Refilling Tanks Instead of Exchanging

The average cost to exchange a propane tank is often 20% higher than it is to refill the same tank! By keeping the same tank, you also ensure that you don't waste money by losing unused fuel. Our comprehensive article on Propane Refill vs Exchange explores just a few of those reasons why it makes sense to refill and reuse.

The Safe Way to Transport Propane Tanks

There are three safety tips to keep in mind when transporting a propane tank.

  1. Close the tank valve
  2. Secure the tank
  3. Ensure there is proper ventilation

When transporting your propane tank for refilling, be sure to keep the propane tank in an upright and secured position. The best way to do this is by securing it with a Tankfoot or EZGO® Propane Tank Holder and Stabilizer
