Fuel Oil

Fuel oil is a liquid petroleum product used for powering combustion engines and boilers. It is typically a dark, viscous liquid that is produced during the refining process of crude oil. Fuel oil is categorized into different grades based on its viscosity, sulfur content, and other physical characteristics.

The most common grades of fuel oil are No. 1, No. 2, and No. 3, with No. 2 being the most commonly used. No. 1 fuel oil has the lowest viscosity and sulfur content, making it ideal for use in portable heaters and smaller furnaces. No. 2 fuel oil is the most common grade used for residential and commercial heating and for powering diesel engines. No. 3 fuel oil is thicker and has a higher sulfur content, making it suitable for use in larger industrial boilers.

Fuel oil is commonly used for heating homes and buildings, powering diesel engines, and as a feedstock for the production of other products, such as asphalt and lubricants. However, due to its high sulfur content, fuel oil is a major contributor to air pollution and greenhouse gas emissions. As a result, many countries have implemented regulations to limit the use of high-sulfur fuel oil and promote the use of cleaner alternatives, such as natural gas and renewable energy sources..
