Gasoil or D2 is a group of petroleum distillation products having boiling points between Kerosene and lubricating oil. The term originally referred to the product of oil gas works that was added to the product of coal gas works to produce improved illuminating gas.
D2 is an abbreviation for Gas oil. It is the second distillate from the processing of crude oil. It can be used without reformers and additives. D2 has helped in a major reduction of wasted energy, pollution and waste.
It is a heavy oil and it is created by a process of fractional distillation of petroleum. It is used as a fuel for automotive applications and in heating. Diesel engines are used worldwide due to higher thermodynamic efficiency and thus fuel efficiently. Gas oil, which is used in off–road vehicles is often called red diesel.
The 305–82 version of D2 has a lower sulphur content. The GOST 305–82 variant of Gas oil and D2 meets the ISO industry standards with a suplhur content of 0.2% maximum. This low sulphur content refers to Ultra Low Sulphur fuel. D2 Oil GOST 305–82 also creates less pollution. Since 2006, nearly all of the petroleum–based diesel fuels available in North America and Europe have been of a ULSD type.
