One main difference between gas oil and kerosene is their **boiling point**. Gas oil has a higher boiling point, typically ranging from 250°C to 350°C (482°F to 662°F), making it more suitable for use in diesel engines and heating systems. Kerosene, on the other hand, has a lower boiling point, generally between 150°C and 300°C (302°F to 572°F), and is commonly used in jet engines and as a lighter heating fuel.

What Is Gas Oil?
Gas oil, also known as diesel oil or distillate fuel, is a type of hydrocarbon fuel derived from the fractional distillation of crude oil. It is characterized by its heavier molecular weight and higher boiling point compared to lighter fuels like kerosene. Typically, gas oil boils at temperatures ranging from 250°C to 350°C (482°F to 662°F), making it suitable for applications requiring a denser, more energy-dense fuel.
Gas oil is predominantly used as diesel fuel in internal combustion engines, such as those found in trucks, buses, and industrial machinery. Its high energy content makes it ideal for these applications, where efficiency and power are crucial. In addition to its use in transportation, gas oil is also employed in heating systems, particularly in industrial and commercial settings, due to its ability to produce a steady and reliable heat output.
The fuel is known for its higher viscosity and density, which affects how it flows and combusts. Gas oil often has a darker color and a more pungent odor compared to lighter fuels. Due to its properties, it requires careful handling and storage to ensure optimal performance and safety.
What Is Kerosene?
Kerosene is a light hydrocarbon fuel derived from the fractional distillation of crude oil. It is characterized by its relatively low boiling point, which typically ranges between 150°C and 300°C (302°F to 572°F), making it a lighter and less dense fuel compared to heavier hydrocarbons like gas oil.
Kerosene is widely used in various applications due to its versatile properties. In aviation, it serves as jet fuel, powering jet engines in commercial and military aircraft. Its high energy content and stable combustion make it ideal for this purpose. In addition to aviation, kerosene is commonly used as a heating fuel in some residential and commercial systems, particularly where other fuel sources are less practical.
Kerosene is also used as a solvent in various industrial processes and as a component in certain cleaning products. It typically has a clear or pale yellow color and a relatively mild odor compared to heavier fuels. Due to its lighter nature and lower viscosity, kerosene flows more easily and is more fluid, which affects how it is handled and stored.
