Propane autogas is the leading alternative fuel in the United States and the third most commonly used vehicle fuel across the globe, following gasoline and diesel.
More than 90 percent of the United States propane autogas supply is produced domestically, with an additional 7 percent from Canada.
Almost 75 percent of propane used in the U.S. comes from natural gas refining, and the remaining comes from petroleum during the refining process.
Using American-made propane autogas helps the nation’s energy security goals and reduces the nation’s dependence on imported oil.
