What is Petroleum/Petrol?

It is the combination of Greek words 'Petra' for rocks and 'Elaion' for oil. The term 'Petraoleum' was used in 10th-century old English sources, which became 'Petroleum' and then later simply 'Petrol'.

In the USA, manufacturers term it as the 'Gasoline'.  However, the consumers locally also call it the 'Gas' which is the short-form of the 'Gasoline'.

How the manufacturers extract the Petrol fuel?

Crude Petroleum undergoes the processes of fractional distillation. This process extracts various petroleum products such as the light distillates (LPG, gasoline, naphtha), middle distillates (kerosene, diesel), heavy distillates and, residuum (heavy fuel oil, lubricating oils, wax, asphalt) etc. The manufacturers extract them according to their respective boiling temperatures.

Characteristics of the Petrol Fuel:

Petrol is easier & lighter to burn whereas Diesel is difficult & heavier to burn cleanly. This is the fundamental difference between the two technologies; making their respective engines technically different from each other. Petrol engines use 'Spark Ignition' whereas Diesel engines use 'Compression Ignition' technology.

Shell, BP, CNPC, ExxonMobil, Chevron, and Gazprom are some of the biggest oil and gas manufacturing companies in the world. Some of these have the annual revenue of US$ 100 billion.
