Petroleum product, such as gasoline, kerosene, home heating oil, residual fuel oil and lubricating oils, come from one source. Crude oil is found below the earth surface, as well as under large bodies of water, from a few hundred feet below the surface to as deep as 25.000 feet into the earth interior. Crude oil is obtained by drilling a hole through the earth, but sometimes more dry holes are drilled than those producing oil. Pressure at the source, or pumping, forces the crude oil to the surface.

Crude oil wells flow at varying rates, from ten to thousands of barrel per hour. Petroleum products vary greatly in physical appearance: thin, transparent, or opaque. Their chemical composition are made up of only two elements: carbon and hydrogen, which from two compounds called hydrocarbons. Other chemical elements found in the union with the hydrocarbons are few and are classified as impurities. Trace elements are also found, but these are of such minute quantities that they are disregarded.

The various petroleum products are refined from the crude oil by heating and condensing the vapors of crude oil. These products are called light oil such as gasoline, kerosene and distillate coil.(Sumber: UNAS 2008)
