Propane is a clean-burning, high-energy alternative fuel that’s been used to power light-, medium-, and heavy-duty propane vehicles. This fuel only accounts for about 2% of energy used in the United States of which less than 2% is used for transportation fuel.
Propane is also known as liquefied petroleum gas (LPG) or autogas, and is usually stored under pressure inside a tank, becoming a colorless and odorless liquid. When pressure is released, propane turns into a gas used for combustion. Propane autogas has a high octane rating and excellent properties for spark-ignited internal combustion engines, but it also has a slightly lower Btu than gasoline vehicles.
LPG is non-toxic and poses no threat to soil, surface water, or ground water.
