Liquefied petroleum gas (often called LPG or Autogas) is a mixture of hydrocarbon gases; usually propane and butane.
LPG is used increasingly in vehicles, as it is environmentally friendly and relatively cheap at the same time.
Replacing petrol with LPG can reduce damage to the ozone layer.

"LPG burns cleanly with no soot and very few sulfur emissions, posing no ground or water pollution hazards."
"Large amounts of LPG can be stored in bulk tanks and can be buried underground if required. Alternatively, gas cylinders can be used."
"LPG has a typical specific calorific value of 46.1MJ/kg compared to 42.5MJ/kg for diesel and 43.5MJ/kg for premium grade petrol."
"When LPG is used as fuel , it is often referred to as autogas. In some countries, LPG has been used since the 1940s as an alternative fuel for spark ignition engines."
"LPG advantages are that it is non-toxic, non-corrosive and free of any additives and has a high octane rating (108 RON). LPG burns more cleanly than petrol or diesel and is especially free of the particulates from the latter."
