Gas is a blend, but it's a blend of different organics (mostly in the C6-C7 range) that are produced by distilling crude oil. The cyclohexane, benzene, toluene, etc are components in the crude oil. We separate them from the oil and then add other reagents to make it gasoline.
When you distill crude oil, you get a multitude of products. For the most part, you get gas fuels such as propane and butane, volatile fuel (gasoline) and non-volatile fuels like diesel fuel, jet fuel, and heating oil.
Natural gas is also ususally extracted along with oil. According to a friend of mine who is an engineer at a oil field, when natural gas was not in such demand, they'd just burn it right there and get rid of it. Nowdays, they cryo-distill it to produce methane and ethane.
