Gasoline or gasoline is a product derived from crude oil/petroleum. It is derived during the fractional distillation process and has a transparent liquid form. It is not used in its raw form. Various additives such as ethanol are added to be used as fuel for passenger cars. gasoline blending components called gasoline blendstocks, which require blending with other liquids to make finished motor gasoline. Most finished motor gasoline is produced at blending terminals, where gasoline blendstocks, finished gasoline, and fuel ethanol are blended to produce finished motor gasoline in different grades and formulations.
