Petrol vs. LPG: What's the Difference?

Edited by Sumera Saeed || By Sawaira Riaz || Published on January 16, 2024
Petrol, a liquid fuel used mainly in internal combustion engines, is derived from crude oil; LPG (Liquefied Petroleum Gas) is a gas at room temperature, used as fuel in heating appliances and vehicles.

Key Differences

Petrol, a liquid obtained from refining crude oil, is primarily used as fuel in cars and motorcycles. LPG, a mixture of propane and butane, is a gas that turns to liquid under pressure and is used in heating, cooking, and as automotive fuel.
