Â­ Crude oil is the term for unprocessed oil, the stuff that comes out of the ground. It is also known as petroleum. Crude oil is a fossil fuel, meaning that it was made naturalÂ­ly from decaying plants and animals living in ancient seas millions of years ago -- most places you can find crude oil were once sea beds. Crude oils vary in color, from clear to tar-black, and in viscosity, from water to almost solid.
We use the term 'petroleum products after crude oil is refined in a factory. Crude oil can exist either deep down in the earth's surface or deep below the ocean beds.

Saudi Arabia, USA, Russia, China and Iran are among the top crude oil producers in the world, and the USA is the world's biggest consumer of crude oil, followed by China.
