What is the relationship between Oil and Gas?

Question

What is the relationship between oil ( the earths natural resource) and Gas at the pumps, that fill cars?

Answer 1

Probably about $4 a gallon.

Answer 2

Gas is made from refined oil. No oil, no gas.....

Answer 3

gas (gasoline)  is made from oil (crude oil).  The gas represents the more volatile hydrocarbons that easily move from liquid to gaseous phase (that is where the term gas came from).  Refineries are used to convert crude oil into gasoline.  Gas can also refer to natural gas which is often associated with crude oil.

Answer 4

Gasoline is a refinement of crude oil. The process used for this refinement is called "cracking". It takes the long chain hydrocarbons and waxes found in crude oil and heats them up to break them into smaller chains. This process is done in a tall cracking tower where crude oil is heated at the bottom of the tower and its lighter constituents are collected at different points up the tower. Longer chaing hydrocarbons for motor oils and lubricants are collected at the bottom of the tower. Gasoline are medium length hydrocarbons such as octane (hence the octane rating on gasoline) and are collected above the longer chained hydrocarbons. At the very top of the tower you get gases like methane, butane and propane. These are sometimes burned off in flares (the flames you see coming from stacks at oil refineries). Additives like ethanol are then added to gasoline to increase the oxygen available for burning in your car's motor. This decreases the amount of soot and incomplete combustion. Hope this helps!
