Diesel fuel, often simply referred to as diesel, is a liquid fuel designed for use in diesel engines, which include those in trucks, trains, buses, boats, and agricultural vehicles. D2 diesel fuel, specifically, is a refinery abbreviation for gasoil, which is the second distillate from crude oil. D2 can be used without reformers and additives, and was used in the first engines before the invention of the petrol car. The principal difference between gasoil and D2 is their sulphur content.

D2 is a refinery abbreviation for Gasoil
Diesel fuel is a liquid fuel used in diesel engines, which are a type of internal combustion engine. Diesel engines are used in trucks, trains, buses, boats, agricultural vehicles, construction engines, and some cars. Diesel fuel is also used in electricity generators, which are common in industrial facilities, large buildings, hospitals, and utilities.
The primary difference between Gasoil and D2 is their sulphur content. Sulphur was previously used as a lubricant in diesel fuel, but it has been removed due to its harmful emissions. Ultra-low-sulfur diesel (ULSD) is a type of diesel fuel with substantially lowered sulfur content. Since 2006, almost all petroleum-based diesel fuel available in Europe and North America has been of the ULSD type. The reduction of sulphur in Gasoil has contributed to decreased pollution in many cities.
The GOST variant for D2/Gasoil is GOST 305-82, which specifies a sulphur content of 0.02 MAX according to the ISO standard. However, the ANSI standard refers to this as "Ultra Low Sulphur" and defines "Low Sulphur" as 0.2% (2000ppm). The usual variants traded are EN590 and EN560, which are specified by ISO in Paris and may be sold in the US while complying with EPA regulations.

Gasoil is the second distillate from crude oil
Diesel fuel, also known as diesel oil, heavy oil, or simply diesel, is a liquid fuel used in diesel engines. Diesel engines are a type of internal combustion engine that uses compression to ignite the fuel without a spark. Diesel fuel is produced from various sources, most commonly petroleum, but also biomass, animal fat, biogas, natural gas, and coal liquefaction. The most common type of diesel fuel is a fractional distillate of petroleum fuel oil, but alternative sources that are not derived from petroleum, such as biodiesel, biomass-to-liquid (BTL), or gas-to-liquid (GTL) diesel, are also used.
Gasoil, also known as D2, is a type of diesel fuel that is the second distillate from crude oil. It can be used without reformers and additives, making it suitable for early diesel engines that lacked spark plugs. The primary difference between gasoil and other types of diesel fuel is its sulphur content. Gasoil typically has a lower sulphur content, which has contributed to reduced pollution in many cities. The ISO standard for sulphur content in gasoil is 0.02% MAX, while the ANSI standard for Ultra Low Sulphur is 0.2%.
In some countries, the term gas oil is used interchangeably with diesel fuel. For example, in France, diesel fuel is called "gazole." However, in the UK, gas oil refers specifically to red diesel, which is a low fuel duty variant of regular road diesel. Red diesel is blended with a red dye marker to help identify illegal use on public roads, as it is taxed at a lower rate than regular diesel. While gas oil is primarily used in agricultural and industrial sectors, it is illegal for use in road vehicles.
The use of gasoil, or D2, as a refinery abbreviation for diesel fuel, highlights its importance as an early source of fuel for diesel engines. With its ability to be used without reformers and additives, D2 played a crucial role in the development of diesel engine technology before the invention of petrol-based engines. Today, ultra-low-sulfur diesel (ULSD) is the standard for diesel fuel in Europe and North America, offering reduced emissions and improved performance.

Gasoil can be used without reformers and additives
Gasoil, also known as red diesel, is a refinery abbreviation for the second distillate from crude oil. It is a type of diesel fuel that can be used without reformers and additives.
Gasoil is a standard diesel that has been blended with a red dye marker. This dye is added to help authorities quickly identify illegal use. Gasoil is illegal to use on public roads and is reserved for off-road vehicles and machinery. It is commonly used in the agricultural industry, powering farm vehicles such as tractors, utility vehicles, and combine harvesters. It is also used in emergency generators for hospitals and non-commercial buildings.
Gasoil differs from regular diesel primarily in its sulphur content. Sulphur acts as a lubricant in diesel fuel. However, the reduction of sulphur content in gasoil has contributed to decreased pollution in many cities. Ultra-low-sulphur diesel (ULSD) is a type of diesel fuel with substantially lowered sulphur content. Since 2006, almost all petroleum-based diesel fuel available in Europe and North America has been of the ULSD type.
The use of ULSD allows for the application of advanced emissions control technologies, significantly reducing harmful emissions from diesel combustion. Testing has shown that emissions control devices used in conjunction with ULSD can reduce the exhaust output of ozone precursors and particulate matter to near-zero levels.
Gasoil, or D2, is an example of ULSD, adhering to international standards for sulphur content. It can be used without reformers and additives, making it suitable for diesel engines that require no spark plugs, such as the original engine invented by German scientist Rudolf Diesel.

Gasoil has a lower sulphur content than diesel
D2 is a refinery abbreviation for Gasoil, which is the second distillate from crude oil. It can be used without reformers and additives. The main difference between Gasoil and D2 is their sulphur content.
Gasoil, also known as red diesel, is a low fuel duty variant of regular road diesel. It is blended with a red dye marker to signify illegal use. Gasoil is used in a variety of sectors, including agriculture, forestry, rail transport, and in backup generators for hospitals and non-commercial buildings. It is also used to power machinery and equipment in several commercial and industrial sectors.
The reduction of sulphur content in gasoil has contributed to reduced pollution in many cities. The US EPA introduced a limit of 4% sulphur in gasoil about 10 years ago, with Europe and the rest of the world following suit. The GOST variant for D2/Gasoil is GOST 305-82, which specifies a maximum sulphur content of 0.02%, considered "Ultra Low Sulphur" by ANSI standards.
Since 2006, almost all petroleum-based diesel fuel available in Europe and North America has been of the Ultra-Low-Sulphur Diesel (ULSD) type, allowing for the application of advanced emissions control technologies that substantially lower harmful emissions from diesel combustion.

Ultra-low-sulphur diesel (ULSD) reduces harmful emissions from diesel combustion
Diesel fuel is a refined crude oil product that powers most trucks, trains, buses, boats, agricultural vehicles, and construction engines. It is also used in electricity generators. Diesel fuel is a distillate, closely related to heating oil, but with lower sulphur content.
D2 is a refinery abbreviation for Gasoil, which is the second distillate from the crude oil. It can be used without reformers and additives. D2 was used in the first diesel engines, invented by a German named Diesel, which required no spark plugs. The principal difference between Gasoil and D2 is the content of sulphur.
Ultra-low-sulphur diesel (ULSD) is diesel fuel with substantially lowered sulphur content. Since 2006, almost all petroleum-based diesel fuel available in Europe and North America has been ULSD. The reduction in sulphur content allows for the application of advanced emissions control technologies, which substantially lower the harmful emissions from diesel combustion.
Testing by engine manufacturers and regulatory bodies has found that the use of emissions control devices in conjunction with ULSD can reduce the exhaust output of ozone precursors and particulate matter to near-zero levels. ULSD reduces the emission of sulphur dioxide (SO2), a compound harmful to health and the environment, and a precursor to acid rain. The use of ULSD decreases the formation of particulate matter, which is directly related to respiratory health problems, such as asthma and heart disease.
ULSD is also used to reduce emissions from power stations. For example, boilers at Castle Peak Power Station were converted to burn ULSD to cut down on sulphur dioxide emissions.
