In Armenia, for example, the transport ministry estimates as many as 20 to 30% of vehicles use autogas, because it offers a very cheap alternative to both diesel and petrol, being less than half the price of petrol and some 40% cheaper than diesel. The recent [when?] rises in oil-derived fuel prices has significantly increased the difference.
Liquefied petroleum gas, also referred to as liquid petroleum gas (LPG or LP gas), is a fuel gas which contains a flammable mixture of hydrocarbon gases, specifically propane, n-butane and isobutane. It can sometimes contain some propylene , butylene , and isobutene .

Among the beneficiaries of the current state of the oil market are U.S. motorists, who have seen gasoline prices fall to their lowest in 2 1/2 years to near $3 a gallon.
Liquefied petroleum gas (LPG) is a mixture of several hydrocarbons, mainly propane, butane, and ethane. The gas mixes readily with air, allowing for more complete combustion. The fuel costs less than regular gasoline, but LPG has lower energy per unit volume, so its fuel economy and efficiency are lower.
This lower density is a property of the lower molecular weight of propane (LPG's chief component) compared to gasoline's blend of various hydrocarbon compounds with heavier molecular weights than propane. Conversely, LPG's energy content by weight is higher than gasoline's due to a higher hydrogen-to-carbon ratio.
