Aviation Kerosene Colonial Grade 54 (JP54), is essentially a broker slang for aviation kerosene used in turbine driven aircraft. Aviation kerosene referenced as JP54, in reality is Jet A, Grade 54. No one produces Russian aviation jet fuel JP54. Many novice 'traders' sometimes refer to Jet Fuel as JP54. Beware of "brokers" or "agents" purporting to sell "JP54". Most likely they do not know what they are selling. Only available in the USA.

Jet A-1 is a kerosene grade fuel suitable for most turbine engined aircraft. It has a flash point minimum of 38 degrees C (1000F) and a freeze point maximum of -47 degrees C. It is widely available outside the U.S.A.

D6 Virgin Fuel Oil is Residual Fuel Oil and is of a high-viscosity state. Fuel Oil D6 requires preheating to 220-260 degrees Fahrenheit in order to be utilized. Since Fuel Oil D6 requires preheating, it cannot be used in small ships or boats or cars. However, large ships and power plants utilize residual fuel oil.

D2 is known as Gasoil or diesel fuel. D2 grades are based upon the amount or sulfur content. D2 has a PPM content between 50 and 200 max.

EN590 describes the physical properties that all automotive diesel fuel must meet if it is to be sold in the UK, the rest of the European Union, Croatia, Iceland, Norway and Switzerland. EN590 for diesel (in Europe) has been around for almost 20 years. EN590 has as a PPM content of 10 max.

Automotive Gas Oil, or AGO, is the name given to fuel intended for use in road vehicles (trucks, buses, vans and cars) powered by diesel engines. AGO is used in two main types of vehicle: Heavy-duty vehicles, such as trucks and buses. Light-duty vehicles, such as vans and passenger cars. AGO has a PPM content of 3000 max.

Mazut is a heavy, low quality fuel oil, used in generating plants and similar applications. In the United States and Western Europe, Mazut is blended or broken down, with the end product being diesel.

Octane rating or octane number is a standard measure of the performance of an engine or aviation fuel. The higher the octane number, the more compression the fuel can withstand before detonating (igniting). In broad terms, fuels with a higher octane rating are used in high performance gasoline engines that require higher compression ratios. There's also 87 Octane Gasoline.
