Diesel fuel

Diesel fuel is a combustible liquid that is used as a fuel for diesel engines, usually obtained from crude oil fractions that are less volatile than those used in gasoline. In the production of diesel fuel, there are fewer processing steps than gasoline.

The reason diesel is more popular with truck drivers is that it is most efficient and economical for such large bodies and engines.

Most trucks and lorries, and trains, buses, boats, agricultural, construction, and military vehicles, have diesel engines.
