How do you find nearby propane refill stations?

Companies such as U-Haul and AmeriGas offer online refill station locators on their websites. The U.S. Department of Energy offers an interactive map of propane refill stations online, intended for alternative fuel-source vehicles.

Some stores, such as Tractor Supply, offer propane tank refills and propane tank exchanges. Most propane refill stations are intended for small-tank refills and can only fill tanks up to 100 pounds.

Propane-powered vehicles operate at a significantly higher pressure level than consumer propane tanks. Propane engines maintain an average pressure level of 150 pounds per square inch, which means that small-tank refill stations often struggle to refuel them.
