Fuel Oils, Color : light yellow, radish, etc.

Fuel oil is a petroleum-based liquid fuel derived from crude oil during the refining process. It is primarily used for heating, power generation, and industrial applications, where it is burned to produce heat or energy.Fuel oil varies in thickness (viscosity) and quality, depending on how much refining it undergoes. Lighter fuel oils flow easily and ignite more readily, while heavier fuel oils are thicker, darker, and require preheating before use.
