Fuel oil is a fraction obtained from petroleum distillation, either as a distillate or a residue. It is also known as heavy oil, marine fuel or furnace oil. Broadly, fuel oil is any liquid fuel that is burned in a furnace or boiler for the generation of heat or used in an engine for the generation of power. The term fuel oil is also used in a stricter sense to refer only to the heaviest commercial fuel that can be obtained from crude oil, i.e., heavier than gasoline and naphtha.
