CRUDE OIL

Crude Oil is Petroleum which is directly out of the ground and is a remarkably varied substance, both in its use and composition. Crude oil is formed from the preserved remains of prehistoric zooplankton and algae, which have been settled to the sea (or lake) bottom in large quantities under anoxic conditions. It was formed over millions of years from the remains of tiny aquatic plants and animals that lived in ancient seas due to compression and heating of ancient organic materials over geological time. The oldest oil-bearing rocks date back to more than 600 million years.

GASOLINE / PETROL

Automotive gasoline and gasoline-oxygenate blends are used in internal combustion spark-ignition engines. These spark ignition engine fuels are primarily used for passenger cars. They are also used in off-highway utility vans, farm machinery and in other spark ignition engines employed in a variety of service applications.

Gasoline is a complex mixture of relatively volatile hydrocarbons that vary widely in chemical & physical properties and are derived from fractional distillation of crude petroleum with a further treatment mainly in terms of improvement of its octane ratin
