'''Oil''' is a [[viscosity|viscous]] [[liquid]] that is not [[solubility|soluble]] in [[water]] and which is used for mainly for lubrication and [[fuel]].
There are two main types of oil. One is derived from plants, such as [[olive]]s, and the other, [[petroleum]], is obtained from geological sources.
Whilst many [[liberal]]s and [[environmentalist]]s argue for investment in less efficient and more expensive sources of energy with the claim that petroleum sources will one day run out, recent research in to [[Abiotic oil]] has shown that this may not be the case.<ref>http://www.wnd.com/news/article.asp?ARTICLE_ID=59991</ref>
== Uses ==
Uses of oil include the following:
* [[Heat]]ing, by [[burn]]ing the oil
* Illumination, in oil lamps
* Generation of [[electricity]], by burning the oil to turn water to steam used to run generators
* Lubrication
* Anointing
* Manufacture of perfumes
* [[Cooking]], to add [[flavor]], and to improve [[heat transfer]]
== Oil in the Bible ==
Oil, probably usually referring to olive oil, appears over two hundred times in the [[Bible]].
* Oil, particularly olive oil, is used in drink offerings to God, but not in sin offerings.<ref>{{Bible ref|Genesis|28|18}}, {{Bible ref|Genesis|35|14}}, {{Bible ref|Leviticus|2}}, {{Bible ref|Leviticus|14}}, {{Bible ref|Numbers|7}}</ref>
* Oil is used for anointing the priests of God by pouring it on their heads. This sanctifies them and makes them holy<ref>{{Bible ref|Exodus|29|2,7,21}}, {{Bible ref|Exodus|30|25}}, {{Bible ref|Leviticus|8}}</ref>. It was also used for anointing the kings of Israel.<ref>{{Bible ref|I_Samuel|10|1}}, {{Bible ref|I_Kings|1|39}}</ref>
* Oil is used for lighting lamps.<ref>{{Bible ref|Exodus|27|20}}</ref>
