Read the FAQ explanation of Comprehensible InputReal Context
Petroleum is a natural, dense liquid that forms deep underground from ancient organic matter. It is the raw material for gasoline and many other products after refining, and it powers vehicles, airplanes, and industry around the world. In everyday English, oil is the broad term; petroleum is more technical and often used in economics, energy policy, or science discussions. The word also covers crude oil in its unrefined state, as well as refined petroleum products like fuels and feedstocks for plastics. Understanding this term helps you discuss energy sources, drilling, refining, and the global trade in fossil fuels.

- Petroleum can mean crude oil or refined products.
