How do I read my gauge?
Your gas gauge is located under the dome at the top of the tank. Reading your gas gauge is not complicated. You'll see bold black numbers encircling the gauge and a single pointer needle. The pointer will indicate a number that represents a percentage.

Due to the physical properties of propane, your tank is considered full at 80% (allowing for the expansion of propane vapor). A propane tank is in IMMEDIATE NEED of refilling at 30%. For your safety and protection, it is best to fill your tank BEFORE the gauge goes below 30%.


How many gallons of Propane do I have in my tank based on the percentage?
This chart shows how many gallons of propane you have in your tank at a given percentage. A propane tank is considered full at 80%.
 
GAUGE READS NUMBER OF GALLONS REMAINING

60% 90 120 150 300
50% 75 100 125 250
40% 60 80 100 200
30% 45 60 75 150

IF GAUGE READS LESS THAN 30%, ORDER GAS NOW!

 

If your tank size is not listed in the chart on this page, use the following formula:

Tank Size X Percentage = Gallons

Example:
A 250 gallon tank with a 50% gauge reading:
250 X .50 = 125 gallons
