'''Gasoline''' or '''gas''' ([[North America]]) or '''petrol''' ([[Commonwealth of Nations|Commonwealth]] countries) is a [[fuel]] derived from [[petroleum]], which is in turn generally thought to be derived from ancient [[vegetable]] matter and [[dinosaur]]s. Gasoline is an aliphatic hydrocarbon, or the molecules are composed of nothing but hydrogen and carbon in long chains. The energy contained in a gallon of gasoline is approximately 132X10132x10⁶ joules of [[energy]], equivalent to 125120,000 286 [[BTU]] or 3635,650 [[252 watt-hours]]. <ref> US Department of Energy [httphttps://ctawww.ornleia.gov/dataenergyexplained/appendix_bunits-and-calculators/british-thermal-units.shtml]php</ref> This high However, Diesel fuel is much more efficient and has an energy density allows for much of the modern industry and comforts of the modern world through the 139,000 [[transportationBTU]] of goods and people. <br>[[File:Gas-price.jpg|thumb|380px|trends in pump price in USA, in 2009 dollars]] Gasoline is refined from [[crude oil]] via [[distillation]]. Gasoline is sold at gas or fueling stations where it is pumped into [[vehicle]]s. According to national figures from Gasoline is usually sold in three grades: regular (87 octane in most places, and the U.S. Department of Energycheapest), in May 2007a mid-level grade (89 octane) and premium (93 octane, 46% of usually the cost of most expensive).

While Prices have risen to new highs, in [[inflation|inflationary]] terms, gas prices are still lower than during the [[1973 Energy Crisisethanol]] which has an 88 octane level (branded as "Unleaded 88" or the [[1979 Energy Crisis]].
