What color is No. 2 Fuel oil?

No. 2 Fuel oil is commonly identified by its red color. This designation is important for a few reasons, primarily related to safety and regulatory compliance. The red dye in No. 2 fuel oil serves to distinguish it from other types of petroleum products, particularly those that are taxed differently such as gasoline and diesel fuel. By coloring No. 2 Fuel oil red, it helps to ensure that users apply it correctly according to its intended purposes, including heating and power generation, without confusion with on-road vehicle fuels.

Additionally, the color coding of fuels is an essential practice in the industry, as it helps prevent illegal use and tax evasion. The use of specific dyes indicates the fuel is not meant for highway use, thus allowing for easier monitoring and enforcement of regulations by authorities. Understanding the color of No. 2 Fuel oil aids in promoting safe handling and compliance with laws governing fuel usage.
