~ Fun Fact ~
The 80% fill rule applies to everyone who owns a 500-gallon propane tank. This is why these tanks should only be filled with a maximum of 400 gallons of propane. Like most liquids, propane expands when it heats up. This is especially true during the hotter summer months.

This expansion of propane can be dangerous, especially if a tank is filled to the brim. When propane heats up, it can increase in volume by almost 17% more than water!
