Nearly 280,000 vehicles in the United States use propane in place of gasoline or diesel fuel. Transportation use of propane is expected to rise as more automakers take advantage of its special properties, such as its higher octane rating than gasoline - so you don't have to sacrifice performance for environmental friendliness. And with a propane-powered vehicle, power, acceleration, payload, and cruise speed are comparable to those obtained with an equivalent internal-combustion engine.

Compared to other alternative fuels, propane can go longer between fill-ups, oil changes, and overhauls, making it the most economical. And propane vehicle tanks are tested to four times the normal operating pressures, and the propane has the lowest flammability range of any alternative fuel.
