Do you ever wonder where gasoline comes from? The answer is crude oil, a thick, flammable, mixture of solid, liquid, and gaseous hydrocarbons. Crude oil, or petroleum, consists of three major classes of hydrocarbons — alkanes, cycloalkanes, and aromatics. The approximate range of hydrocarbons in crude oil is C5H12 to C18H38. These hydrocarbons, along with a number of other substances, comprise the chemical makeup of petroleum.

Petroleum is found in porous rock formations in some areas of the Earth's crust. During the past 600 million years, plants and animals have become buried under layers of rock, which are believed to have later become petroleum. The high organic compound content in petroleum is probably due to the microscopic plankton organism remains.

Petroleum is used mostly by volume for the production of fuel, gasoline, and other energy sources. Therefore, an important property of petroleum is density; a ratio of its mass to its volume. In petroleum production, density is used to give an estimation of the gasoline and kerosene present. This, in turn, determines the price of the gasoline.

The density of petroleum is approximately 800 kg/m3. The specific gravity (density compared to water) of petroleum is 0.8.
