Gas oil, also known as diesel fuel or diesel oil, is a liquid fuel refined from crude oil. It is widely used to power diesel engines in vehicles, trucks, generators, and industrial machinery. With a higher energy density than gasoline, gas oil offers greater efficiency for power generation and transportation.

Its low volatility and stability make it safer for storage and handling, while its reliability and versatility make it a preferred fuel source globally. Gas oil plays a vital role in transportation, agriculture, construction, and manufacturing, driving engines and supporting essential economic activities.
