Automobile diesel fuel (EN 590) Grade E (winter), recommended for use at ambient temperatures up to minus 15 C (limiting filterability temperature).
Diesel fuel EN 590 (EN 590) Grade E is obtained from petroleum refined products and is intended for use as automotive fuel for diesel engines of cars and trucks. Diesel fuel meets the requirements of the international standard EN 590/2000 and is characterized by a low content of sulfur, aromatic hydrocarbons and a high cetane number, which leads to an overall reduction in sulfur oxide emissions, a decrease in the amount of particulate matter in exhaust gases and the formation of deposits in the fuel system of cars and heavy vehicles, reducing exhaust smoke and is the key to good starting properties of the fuel during cold start of the engine.
The oil refining industry produces diesel fuel in accordance with GOST 305-82 of three grades:
L - summer, used at ambient temperatures above 0 C;
3 - winter, used at temperatures up to -20 C (in this case, winter diesel fuel should have a stagnation <-35 C and n <-25 C), or winter, used at temperatures up to -30 C, then the fuel must have a stasis <-45 C and n <-35 C);
- Arctic diesel fuel, the temperature of which is up to -50 C. The sulfur content in diesel fuel of grades L and Z does not exceed 0.2% for type I fuel and 0.5 for type II fuel, and grade A 0.4%
Aviation Jet Fuel is a type of aviation fuel designed for use in aircraft powered by gas-turbine engines. It is colourless to straw coloured in appearance. The most commonly used fuels for commercial aviation are Jet A and Jet A1, which are produced to a standardised international specification. The only other jet fuel commonly used in civilian turbine-engine powered aviation is Jet B, which is used for its enhanced cold-weather performance.
Jet fuel is a mixture of a variety of hydrocarbons. Because the exact composition of jet fuel varies widely based on petroleum source, it is impossible to define jet fuel as a ratio of specific hydrocarbons. Jet fuel is therefore defined as a performance specification rather than a chemical compound.
Aviation Jet Fuel is commonly referred to as JP54. However, this is the wrong terminology as there is no such grade of Jet Fuel. Jet A and Jet A1 are what refineries offer. Aviation Jet fuel Gas is what powers turbine aircraft engines. Worldwide, Jet Fuel is the most used low Sulphur content Kerosene. For instance, Colonial JP54 is similar to Jet A except the energy is 18.4 mj/Kg compared to the 42.8 MJ/kg of Jet A. Most importantly there is also a slight difference in additives.
Aviation Jet Fuel B is used for its extremely cold weather performance. However, aviation Jet fuel Bs lighter composition makes it more dangerous to handle. For this reason, it is rarely used except in very cold climates. A blend of approximately 30% Kerosene and 70% Gasoline. Because of its very low freezing point (60 C (76 F), it is known as a wide cut fuel and has a low flash point as well. Aviation Jet Fuel B is primarily used in some military aircraft. In Canada, it is also used because of its freezing point. Aviation Kerosene standards are published as GOST10227-86. The standard consists of different properties. It separates paraffin and gasoline in the refinery.
Military organisations around the world use a different classification system of JP (for Jet Propellant) numbers. Some are almost identical to their civilian counterparts and differ only by the amounts of a few additives. For instance, Jet A1 is similar to JP 8, Jet B is similar to JP 4. Military fuels are highly specialised products and are developed for very specific applications. Jet fuels are sometimes classified as kerosene or naphtha type. Kerosene type fuels include Jet A, Jet A1, JP 5 and JP 8. Naphthatype jet fuels, sometimes referred to as wide cut Jet Fuel, including Jet B and JP 4.

D6 is also be known as Residual Fuel Oil and is of high-viscosity. This particular fuel oil requires preheating to 220 - 260 Degrees Fahrenheit. D6 is mostly used for generators.
D6 is a type of residual fuel, mainly used in power plants and larger ships. The fuel requires to be preheated before it can be used. 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.
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 percent water and one-half percent mineral soil. D6 fuel is also known as residual fuel oil (RFO), 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, 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.
The price of D6 diesel traditionally rises during colder months as demand for heating oil rises, which is refined in much the same way.In many parts of the United States and throughout the United Kingdom and Australia, d6 diesel may be priced higher than petrol.
D6 Diesel Standards and ClassificationCCAI and CII are two indexes which describe the ignition quality of residual fuel oil, and CCAI is especially often calculated for marine fuels.
Modern mineral base oils are the result of a long and complex distillation and refining processes. The feedstock used is crude oil. This substance is not of uniform quality but consists of several thousands of hydrocarbon compounds in which the elements carbon and hydrogen are present in all molecules and, in part, are bound to other elements.
The hydrocarbons can be divided into three main groups: paraffinic, naphthenic and aromatic. Paraffinic hydrocarbons can be further divided into two subgroups: normal paraffinic and iso- paraffinic.
Paraffinic hydrocarbons are the best lubricants. The distillation process in the refinery separates the hydrocarbons contained in the crude into cuts based on the molecule size.
Furthermore, as many unwanted substances as possible are removed in the process, such as sulphur, aromatic hydrocarbons, paraffin wax, etc. In other words the mineral oil production process is physical cleaning and the end product is so-called paraffinic base oil.
Most of the hydrocarbons in the base oil are paraffinic, but it also contains naphthenic and aromatic molecules. When the finished lubricant, such as motor oil, is made of these, several additive compounds are used to improve the base oil properties.
The final outcome can also be so-called naphthenic base oil, where most of the hydrocarbons are naphthenic. Their cold properties are excellent.
