Propane Tank Sizing Information

Rinker Oil propane tanks


Propane is stored in a variety of different size tanks. Tanks can be above-ground or underground; they hold 80% of their stated capacity. For example: a 500 gallon tank actually holds only 400 gallons.

We've provided some details about both above-ground and underground tank sizes here for your information. Our expert technicians are always eager to come to your home or business and help you determine what size and type of tank you need.
