Crude oil is a naturally occurring material that is rich in hydrocarbons. The crude oil is pumped out of the ground and refined into the gasoline and other oil products. On the stock market, crude oil is considered a valuable energy commodity. Its daily value influences the price consumers pay for a gallon of gas at the pump. As the price of a barrel of crude oil escalates, so does the price of a gallon of gasoline.
