Oil (Civ5)

== Game Info ==
Late-game strategic resource. Used by most of the powerful late industrial-early modern era units.
== Strategy ==
 Oil is the first late-game strategic resource (revealed by the Biology technology), and is quite unique for a number of reasons. First, it is the only strategic resource found on both land and sea. Second, it is the only resource which requires two unique new improvements to access: the Oil Well for land-based sources, and the Offshore Platform for sea-based ones. Finally, its sources are in weird locations: Deserts, Snow, and Tundra terrain or anywhere on Coast tiles. Of these, Oil is most often found in Deserts, which gives desert-based civilizations a unique advantage: they can be all but sure that they will reveal multiple sources already within their territory. Otherwise, be ready to expand immediately after you reveal the Oil sources.
Unimproved, the Oil resource itself doesn't provide a big bonus (only +1), but both of the improvements add a whopping +3 . This is a total of +4 over the base tile yield, which makes the tile really productive. Sea-based sources of Oil are even more useful because of the additional bonuses the Lighthouse and the Seaport provide (+2 and +1 , apart from the Offshore Platform's own bonus).
 Oil is used for most early late-game machines on land, sea, and air, such as armored units and airplanes, so militaristic civilizations should make sure they have plenty of Oil to continue their wars.
