Diesel vs. Petrol: What's the Difference?
Edited by Huma Saeed || By Sumera Saeed || Updated on November 18, 2023
Diesel is a type of fuel derived from crude oil, used in diesel engines, while petrol, also known as gasoline, is used in petrol engines.
Key Differences
Diesel and petrol are both derived from crude oil but differ in their refinement processes. Diesel is heavier and less volatile than petrol. Diesel engines are more fuel-efficient and produce more torque than petrol engines. Petrol engines, on the other hand, are typically lighter and produce more horsepower.

Diesel fuel has a higher energy content and is more efficient for heavy-duty applications. Petrol, also known as gasoline, is more volatile and is used in lighter vehicles for its quick ignition properties. Diesel engines rely on compression ignition, while petrol engines use spark ignition. Diesel is typically cheaper than petrol in some regions, while the opposite may be true in others.

Diesel engines are known for their fuel efficiency and torque, making them suitable for trucks and heavy machinery. Petrol engines are preferred for their power and acceleration, making them suitable for most passenger cars. Diesel fuel is more dense and has a higher energy content than petrol. Petrol is more refined and has a lower boiling point than diesel.

Diesel and petrol have different chemical compositions, with diesel being a heavier fuel with longer carbon chains. This results in diesel having a higher energy content and being more efficient for powering heavy vehicles. Petrol, on the other hand, is lighter and more volatile, making it suitable for lighter vehicles that require quick acceleration.
