Definition & Meaning of "diesel oil"in English

What is "diesel oil"?

Diesel oil is a type of fuel used in diesel engines, which are found in some cars, trucks, buses, and large machinery. It is made from raw oil, like gasoline, but has a different composition that allows it to work efficiently with diesel engines. Diesel oil is more energy-dense than gasoline, meaning it provides more power per gallon, which is why it is commonly used in vehicles that need to carry heavy loads or travel long distances. Diesel engines also tend to be more fuel-efficient, although diesel oil can produce more pollutants than gasoline in certain conditions.
