PRODUCT DESCRIPTION
Virgin Fuel Oil (D6):
-
High Viscosity and Pre-Heating: D6 is characterized by its high viscosity, requiring pre-heating to a temperature range of 104 ºC to 127 ºC (220 ºF – 260 ºF) before use.
-
Composition: It consists of long-chain hydrocarbons, including alkanes, cycloalkanes, and aromatics. D6 is derived from the heaviest commercial fuels that crude oil can yield.
-
The term virgin fuel oil (D6) generally includes any liquid fuel that is burned in a furnace or boiler to generate heat.
-
Virgin Fuel Oil (D6) is also used in an engine to generate power. However, it does not usually include other liquid oils. Such as those with a flash point of approximately 42 °C (108 °F). It is burnt in cotton–or wool–wick burners. In a stricter sense, fuel oil refers only to the heaviest commercial fuels. That crude oil can yield, that is, those fuels heavier than gasoline (petrol) and naphtha. Fuel oil consists of long–chain hydrocarbons, particularly alkanes, cycloalkanes, and aromatics. Small molecules, such as those in Propane, Naphtha, gasoline for cars. Also for aviation jet fuel (kerosene), have relatively low boiling points. They are removed at the start of the fractional distillation process. Heavier petroleum products like diesel fuel and lubricating oil. They are much less volatile and distill out more slowly, while bunker oil is literally the bottom of the barrel. In oil distilling, the only components denser than bunker fuel are carbon black feedstock and bituminous residue (asphalt), which is used for paving roads and sealing roofs.

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.

KEY CHARACTERISTICS
-
Composition: D6 consists of long-chain hydrocarbons, including alkanes, cycloalkanes, and aromatics.
-
High viscosity: Due to its thickness, D6 requires preheating to 220–260°F (104–127°C) before it can be burned effectively.
-
Affordability: D6 is one of the cheapest liquid fuels available because its undesirable properties make it less useful for most applications.
-
High sulfur content: D6 contains a high level of sulfur and other pollutants. Burning it releases sulfur dioxide (SO₂), which contributes to acid rain and air pollution.
-
Handling complexity: Due to its viscosity, D6 requires specialized heating, storage, and pumping equipment, making it impractical for small vehicles or vessels.

Specifications and Standards
D6 Diesel Standards and Classification CCAI and CII are two indexes which describe the ignition quality of residual fuel oil. The CCAI is especially often calculated for marine fuels. Despite this marine fuels are still quoted on the international bunker markets with their maximum viscosity. It is set by the ISO 8217 standard (see below) due to the fact that marine engines are designed to use different viscosities of fuel.
The unit of viscosity used is the Centistokes. The D6 fuel most frequently quoted are listed below in order of cost, the least expensive first:
* IFO 380 – Intermediate D6 Fuel Oil with a Maximum Viscosity of 380 Centistokes.
* IFO 180 – Intermediate D6 Fuel Oil with a Maximum Viscosity of 180 Centistokes.
* LS 380 – Low–Sulphur (<1.5%) Intermediate D6 Fuel Oil with a Maximum Viscosity of 380 Centistokes.
* LS 180 – Low–Sulphur (<1.5%) Intermediate D6 Fuel Oil with a Maximum Viscosity of 180 Centistokes.
* MDO – Marine Diesel Oil.
*MGO – Marine Gas oil.
Oil has many uses; it heats homes and businesses and fuels trucks, ships, and some cars. A small amount of electricity is produced by diesel. It is more polluting and more expensive than natural gas. It is often used as a backup fuel for peaking power plants. In case the supply of natural gas is interrupted or as the main fuel for small electrical generators. In Europe, the use of diesel is generally restricted to cars (about 40%), SUVs (about 90%), and trucks and buses (over 99%). The market for home heating using fuel oil has decreased. This is due to the widespread penetration of natural gas as well as heat pumps.
Residual fuel oil is less useful because it is so viscous that it has to be heated with a special heating system. Before use and it may contain relatively high amounts of pollutants, particularly sulfur (S). It forms sulfur dioxide (SO2) upon combustion. However, its undesirable properties make it very cheap. In fact, it is the cheapest liquid fuel available. Since it requires heating before use, residual fuel oil cannot be used in road vehicles. Also in boats or small ships, as the heating equipment takes up valuable space and makes the vehicle heavier. Heating the oil is also a delicate procedure, which is impractical on small, fast moving vehicles. However, power plants and large ships are able to use residual fuel oil.
Residual means the material remaining after the more valuable cuts of crude oil have boiled off. The residue may contain various undesirable impurities including 2% water and 1½% percent mineral soil. D6 fuel is also known as residual fuel oil (RFO). D6 fuel is by the Navy specification of Bunker C, or by the Pacific Specification of PS–400.
Recent changes in fuel quality regulation now require further refining of the D6. In order to remove the sulfur and it leads to a higher cost. Despite this recent change virgin fuel oil D6 is still less useful because of its viscosity. It also needs to be pre–heated before it can be used. It contains high amounts of pollutants, such as sulfur.
The price of D6 Diesel traditionally rises during colder months as demand for heating oil rises. It is refined in much the same way. In many parts of the USA and throughout the UK and Australia, D6 Diesel may be priced higher than petrol.

D6 Fuel Oil vs. Diesel
-
While diesel is cleaner and easier to handle, D6 Fuel Oil is significantly cheaper when purchased in bulk. Diesel is often reserved for lighter applications, while D6 is preferred for large-scale, high-energy operations.
-
D6 Fuel Oil vs. Natural Gas
-
Natural gas is a cleaner alternative but lacks the energy density and availability of D6 Fuel Oil in certain regions. Additionally, natural gas infrastructure can be cost-prohibitive for industries switching from D6.
-
D6 Fuel Oil vs. Kerosene
-
Kerosene, commonly used for heating and aviation, is far less viscous and has lower energy density. D6’s affordability and industrial compatibility make it the better choice for heavy-duty applications.
