Any of the petroleum products which are less volatile than gasoline and are burned in furnaces, boilers, or other types of heaters. The two primary classes of fuel oils are distillate and residual. Distillate fuel oils are composed entirely of material which has been vaporized in a refinery distillation tower. Consequently, they are clean, free of sediment, relatively low in viscosity, and free of inorganic ash. Residual fuel oils contain fractions which cannot be vaporized by heating. These fractions are black and viscous and include any inorganic ash components which are in the crude. In some cases, whole crude is used as a residual fuel. Distillate fuel oils are used primarily in applications where ease of handling and cleanliness of combustion are more important than fuel price. The most important use is for home heating. They are also used in certain industrial applications where low sulfur or freedom from ash is important. Increasing amounts of distillate fuel oils have been burned in gas turbines used for electricity generation. Residual fuel oils are used where fuel cost is an important enough economic factor to justify additional investment to overcome the handling problems they pose. They are particularly attractive where large volumes of fuel are used, as in electric power generation, industrial steam generation, process heating, and steamship operation.
 
Classes Fuel oil is classified into six classes, numbered 1 through 6, according to its boiling point, composition and purpose. The boiling point, ranging from 175 to 600 C, and carbon chain length, 9 to 70 atoms, of the fuel increases with fuel oil number. Viscosity also increases with number, and the heaviest oil has to be heated to get it to flow. Price usually decreases as the fuel number increases. No. D1 fuel oil, No. D2 fuel oil and No. D3 fuel oil are variously referred to as distillate fuel oils, diesel fuel oils, light fuel oils, gasoil or just distillate. For example, No. D2 fuel oil, No. D2 distillate and No. D2 diesel fuel oil are almost the same thing (diesel is different in that it also has a cetane number limit which describes the ignition quality of the fuel). Distillate fuel oils are distilled from crude oil.
 
::D1
This is similar to kerosene and is the fraction that boils off right after gasoline.
 
::D2
This is the diesel fuel that trucks and some cars run on, leading to the name "road diesel". It is the same thing as heating oil.
 
::D3
This is a distillate fuel oil and is rarely used.
 
::D4
This is usually a blend of distillate and residual fuel oils, such as D2 and D6; however, sometimes it is just a heavy distillate. D4 may be classified as diesel or residual fuel oil.
 

::D5 & D6
These fuel oil are called residual fuel oils (RFO) or heavy fuel oils. More Number 6 oil is produced compared to Number 5 oil, the terms heavy fuel oil and residual fuel oil are sometimes used as names for D6. D5 and D6 are what remains of the crude oil after gasoline and the distillate fuel oils are extracted through distillation. D5 fuel oil is a mixture of 75-80 % D6 oil and 25-20% of D2 oil. D6 oil may also contain a small amount of D2 to get it to meet specifications.
 

Residual fuel oils are sometimes called light when they have been mixed with distillate fuel oil, while distillate fuel oils are called heavy when they have been mixed with residual fuel oil. Heavy gas oil, for example, is a distillate that contains residual fuel oil. The ready availability of grades of fuel oil is often due to the success of catalytic cracking of fuel to release more valuable fractions and leave heavy residue.
