Gas oil is a refined petroleum product falling within the middle-distillate range, positioned between lighter fuels like gasoline and heavier fuels such as fuel oil. It is produced through the fractional distillation of crude oil and is characterized by its higher energy density, efficient combustion properties, and suitability for engines and machinery requiring reliable, sustained power output. Gas oil is commonly known in various markets as diesel fuel, heating oil, or marine gas oil (depending on its grade and sulfur content).

Gas oil is widely used across several sectors:

• As diesel fuel for transportation, including trucks, buses, commercial vehicles, and off-road machinery.

• As heating oil for industrial boilers, furnaces, and power generation units.

• As marine gas oil for ships and small vessels requiring clean, efficient combustion.

• As a feedstock or intermediate fuel in industrial processes, including refineries, manufacturing plants, and agricultural equipment.

Overall, the image represents the scientific and industrial context of gas oil, highlighting its role as a versatile, energy-dense fuel essential to transportation, heating, and industrial operations worldwide.
