  • How do you read a propane tank gauge?

  • The gauge will reflect the percentage of propane in your tank and not the number of gallons. Additionally, when your propane tank is full, it will read 80%, not 100%. From there, multiply the number of gallons by the gauge鈥檚 percentage to get a feel for how much propane is left. Reading a propane tank gauge is not as cut and dry as one would think.

  • How do I know how much gas is in my tank?

  • You can perform some simple math to determine how much gas is in your propane tank. Just multiply the tank鈥檚 capacity by the reading on the tank gauge. For example, if your 500-gallon tank is showing a gauge reading of 60%, that means you have 300 gallons of gas remaining in your tank (500 x 0.6).

  • What do the lines on the gas gauge mean?

  • The lines on the gas gauge are increments of 1/4 representing your gas tanks fuel level. Anything between 2 lines would be an eight. If the needle were between 1/2 and 3/4, this would mean you have 5/8 of gasoline in your tank.

  • What does 1/4 of a tank mean on a gas gauge?

  • If the needle were between 1/2 and 3/4, this would mean you have 5/8 of gasoline in your tank. The line lowest to the bottom would mean you have 1/4 of a tank of gas and you should probably fill up soon, below 1/4 would be close to 1/8 of a tank which means get gas now.
