Petrol vs. Gas: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Updated on October 12, 2023
Petrol, known as gasoline in the U.S., is a liquid fuel for engines; gas can refer to various gaseous substances, including natural gas used for heating.

Key Differences
Petrol is a term primarily utilized in the UK and some other regions to describe what Americans commonly refer to as gasoline. It's a refined product from crude oil and serves as the primary fuel in internal combustion engines found in most vehicles. On the other hand, the word "gas" in American English often refers to gasoline, which can be confusing to those from other parts of the world.

Gas, in a broader context, represents any substance in a state where it expands freely to fill the whole container, devoid of a definite shape. Examples include oxygen, nitrogen, and helium. Additionally, "gas" can pertain to "natural gas," a fossil fuel used primarily for heating and electricity generation.

While petrol is specifically a liquid used for a particular purpose (fueling vehicles), gas encompasses a wider range of materials, from the air we breathe to fuels for various utilities. It's crucial to contextualize the word "gas" as its meaning can shift depending on the situation.

In summation, while petrol refers exclusively to a type of liquid fuel, gas has a more versatile application, spanning from a state of matter to a shorthand reference for various gaseous substances and fuels.

Gas
An aëriform fluid; - a term used at first by chemists as synonymous with air, but since restricted to fluids supposed to be permanently elastic, as oxygen, hydrogen, etc., in distinction from vapors, as steam, which become liquid on a reduction of temperature. In present usage, since all of the supposed permanent gases have been liquified by cold and pressure, the term has resumed nearly its original signification, and is applied to any substance in the elastic or aëriform state.
