Propane is used increasingly for vehicle fuels. In the U.S., 190,000 on-road vehicles use propane, and 450,000 forklifts use it for power. It is the third most popular vehicle fuel in America, behind gasoline and diesel. In other parts of the world, propane used in vehicles is known as autogas. About 13 million vehicles worldwide use autogas.

Propane is also used as fuel for small engines, especially those used indoors or in areas with insufficient fresh air and ventillation to carry away the toxic exhaust of an engine running on gasoline or diesel. More recently, there have been lawn care products like string trimmers, lawn mowers and leaf blowers intended for outdoor use but fueled by propane to reduce air pollution.
More than 1 million commercial establishments, such as hotels, restaurants and laundromats use propane in the same way a homeowner does: for heating and cooling air, heating water, cooking, refrigeration, drying clothes, barbecuing, and lighting. More than 350,000 industrial sites rely on it for space heating, brazing, soldering, cutting, heat treating, annealing, vulcanizing, and many other uses. Petrochemical industries use propane in the manufacture of plastics.
