Reading your gas gauge is easy. You'll see bold black numbers encircling the gauge and a single pointer needle. The pointer will indicate a number that represents a percentage. By nature propane expands when it is heated and therefore a tank that is filled to 80% is considered full to allow for the expansion of the propane. To ensure you don't run out of propane, please check your tank's gauge on a regular basis and contact APP Propane before the gauge reads less than 20%.
