Virgin fuel oil, known as Residual Fuel Oil or D6, is a high-viscosity liquid that plays a crucial role in various industrial applications. Here, we explore the characteristics, applications, and standards associated with this type of fuel oil.

Virgin Fuel Oil D6 is mostly used for generators. Recent changes in fuel quality regulation now require further refining of the D6 in order to remove the sulfur (S), which leads to a higher cost. Despite this recent change, D6 is still less useful because of its viscosity as well as that it needs to be pre–heated before it can be used and contains high amounts of pollutants, such as sulfur. Since it requires pre–heating, it cannot be used in small ships or boats or cars. However large ships and power plants can use the residual fuel oil.

Virgin fuel oil (D6) is a type of residual fuel, mainly used in power plants and larger ships. It is not possible to use it in smaller engines or vessels/vehicles where it is not possible to pre–heat it. D6 is its name in the USA. In other parts of the world it has other names.

Virgin Fuel Oil (D6) remains a vital component in the energy sector, particularly for large–scale applications. Its unique characteristics, coupled with challenges such as viscosity and sulfur content, necessitate ongoing refinements to meet evolving regulatory requirements and market demands. Understanding the global standards and classifications is crucial for both suppliers and consumers in navigating the dynamic landscape of the fuel oil industry.
