Gas oil, also known as red diesel, is a type of diesel fuel that is blended with a red dye marker to distinguish it from regular diesel fuel. It is mainly used for commercial and agricultural purposes, such as powering machinery, generators, and vehicles used off-road. Gas oil is also sometimes used for heat generation, although many businesses have switched to using industrial heating oil. It is produced through the fractional distillation of crude oil and is a high-volume product of oil refineries. Diesel fuel, on the other hand, is commonly used in motor vehicles with compression ignition engines and is also derived from crude oil.

Gas oil and diesel are virtually the same fuel, except gas oil is prohibited from use on public roads
Gas oil and diesel are essentially the same fuel. Gas oil, also known as red diesel, is a type of diesel fuel that is blended with a red dye marker. This dye is added to help authorities distinguish it from regular diesel fuel designated for use on public roads.
The primary difference between gas oil and diesel lies in their taxation and intended use. Gas oil is taxed at a lower rate than regular diesel, making it a more cost-effective option for eligible industries. It is prohibited from use on public roads and is designated for off-road vehicles and machinery. Gas oil is commonly used in the agricultural and farming industries to power tractors, utility vehicles, and combine harvesters. It is also used in sectors such as rail transport, marine, and emergency power generation for hospitals and non-commercial buildings.
Regular diesel fuel, also known as white diesel or road diesel, is widely used in motor vehicles that employ a compression-ignition engine. This type of diesel is subject to the standard VAT rate applied to road fuels, while gas oil is taxed at a lower rate.
It is important to note that using gas oil in vehicles driven on public roads is illegal and can result in fines or even a prison sentence. This restriction is in place due to the lower taxation applied to gas oil, which is intended for off-road and agricultural use.
In summary, gas oil and diesel are virtually the same fuel in terms of their composition, but their taxation and intended use differ. Gas oil is prohibited from use on public roads and is primarily utilized in off-road vehicles and machinery, especially in the agricultural sector.

Gas oil is commonly used in off-road vehicles, machinery and equipment
Gas oil, also known as red diesel, is a fuel commonly used in off-road vehicles, machinery, and equipment. It is a standard diesel that is blended with a red dye marker, indicating that it is designated for off-road use and prohibited for use on public roads. The addition of the red dye was introduced in 1961 to help authorities distinguish it from regular road diesel.
Gas oil is primarily used as a commercial fuel in various industries, powering machinery, generators, and off-road vehicles in sectors such as agriculture, rail transport, and marine. It is also used in grain dryers, although industrial heating oil (IHO) is considered a better option for this purpose. Additionally, gas oil is used in emergency generators for hospitals and non-commercial buildings.
The use of gas oil in off-road vehicles offers a cost-effective alternative to regular diesel due to its lower tax rate. While regular diesel (DERV) purchased at petrol stations incurs a higher tax rate, gas oil is taxed at a lower rate, making it a more economical option for eligible industries. This difference in taxation has led to the development of methods to distinguish between the two types of diesel, with the addition of the red dye marker in gas oil being one of the most recognisable indicators.
Historically, gas oil was used for heating homes and businesses before the widespread adoption of natural gas. However, with the introduction of diesel engine road vehicles in the early 20th century, gas oil became a popular fuel choice for vehicles. Despite this shift towards vehicular use, gas oil continued to be utilised for heating in both commercial and domestic settings. In recent years, however, businesses and domestic users have transitioned to alternative heating oils, such as industrial heating oil and kerosene, respectively.

Gas oil is also known as red diesel due to the red dye marker added to it
Gas oil, also known as red diesel, is a type of fuel used in off-road vehicles and machinery. It is functionally the same as white diesel, which is used in road vehicles, but with a few key differences.
The name 'red diesel' comes from the red dye that is added to gas oil to differentiate it from standard diesel and prevent illegal use in road-going vehicles. The red dye does not change the fuel's properties but allows authorities to identify illegal misuse through random checks and dip testing. The dye can also stain the interior of a fuel tank, making it easier for police officers and HMRC to detect and prosecute fuel fraud.
The addition of the red dye to gas oil was introduced in the mid-20th century, specifically from 1961 onwards. This was to distinguish it from regular road diesel, which is designated for use on public roads. Gas oil is subject to a lower level of excise duty than white diesel, making it a more cost-effective alternative for off-road vehicles and machinery.
The use of gas oil is restricted to off-road vehicles and machinery, such as those used in the agricultural, rail transport, and marine sectors. It is illegal to use gas oil in road-going vehicles, and doing so can result in a hefty fine or prison sentence.

Diesel fuel is produced from various sources, the most common being petroleum
Diesel fuel, also known as diesel oil, heavy oil, or simply diesel, is a liquid fuel used in diesel engines. These are internal combustion engines in which fuel ignition occurs without a spark, as a result of the compression of inlet air and the injection of fuel. Diesel fuel is produced from various sources, with the most common being petroleum.
Petroleum diesel is produced by the fractional distillation of crude oil between 200 and 350 °C at atmospheric pressure. This results in a mixture of carbon chains containing between 9 and 25 carbon atoms per molecule. This fraction is then subjected to hydrodesulfurization. However, "straight-run" diesel often has insufficient supply and quality, so other sources of diesel fuel are blended in. One major source of additional diesel fuel is obtained by cracking heavier fractions using visbreaking and coking. This technology converts less useful fractions, but the product contains olefins (alkenes) which require hydrogenation to give the desired saturated hydrocarbons.
Other sources of diesel fuel include biomass, animal fat, biogas, natural gas, and coal liquefaction. Synthetic diesel can be produced from many carbonaceous precursors, with natural gas being the most important. Raw materials are converted to synthesis gas, which is then converted to synthetic diesel using the Fischer-Tropsch process. Biodiesel is another alternative, produced from vegetable oil or animal fats (biolipids) which are mainly fatty acid methyl esters (FAME). Biodiesel can be produced from various types of oils, with common sources being rapeseed oil in Europe and soybean oil in the US.
Diesel fuel has many colloquial names. In the UK, diesel fuel for road use is often called diesel or white diesel to differentiate it from reduced-tax agricultural products like red diesel. The official term for white diesel is DERV (Diesel-Engine Road Vehicle). In Australia, diesel fuel is known as distillate, while in Indonesia, Israel, and the Middle East, it is known as Solar, a trademarked name from Pertamina, Indonesia's national petroleum company. The term gas oil (French: gazole) is also used to refer to diesel fuel, particularly in the UK where it is used to describe diesel fuel designated for off-road use.

Diesel fuel is refined from crude oil and from biomass materials
Diesel fuel is a liquid fuel designed for use in a diesel engine, which is a type of internal combustion engine. Diesel engines are named after their inventor, Rudolf Diesel, who patented his original design in 1892. Diesel fuel is commonly referred to as diesel, diesel oil, heavy oil, DERV (diesel-engine road vehicle), distillate, gas oil, or white diesel, among other names.
Diesel fuel is refined from crude oil and biomass materials. Crude oil is a naturally occurring liquid that can be refined into various fuels and other petroleum-based products. The refining process involves heating the viscous liquid to over 400 degrees Celsius, turning it into vapour, which then enters a fractional distillation tower. As the vapour rises and cools, it transforms into different fuels depending on its temperature and the length of its hydrocarbon chains. Diesel fuel is one of the distillates obtained at a certain temperature range.
The production of diesel fuel from biomass involves the use of renewable sources such as vegetable oils, animal fats, recycled cooking grease, and biomass itself. The common method for converting biomass into ethanol, which is a type of biofuel, is called fermentation. During fermentation, microorganisms like bacteria and yeast metabolize plant sugars and produce ethanol. Biodiesel, derived from biomass, serves as a cleaner-burning replacement for petroleum-based diesel fuel. It is compatible with today's engines and infrastructure, making it a viable alternative.
The specific processes and sources for refining diesel fuel can vary, and different regions may have different standards and names for diesel fuel.
