Liquid propane or propane autogas has been used worldwide as a vehicle fuel for decades.

More and more fueling locations have seen success adopting propane autogas to service customers, and propane autogas networks are popping up in California and the Pacific Northwest, where alternative fuels have been heavily incentivized and widely adopted.
