Hello, I'm a chemical engineer with a focus on fuel science and technology. I've spent years studying the various types of fuels and their properties, which includes a deep dive into the specifics of "red diesel". Let's explore what makes red diesel red and its unique characteristics.
Firstly, the coloration of red diesel is intentional and serves a specific purpose. The term "red diesel" is commonly used in the United Kingdom and refers to a type of diesel fuel that is dyed red. This coloring is not for aesthetic purposes but is a regulatory measure to distinguish it from regular diesel fuel that is used in road vehicles. The dye used to color the diesel red is called "marker dye" or "dye marker," which is a chemical compound that imparts a distinct red hue to the fuel.
The use of red diesel is restricted to certain applications to ensure that it is not used in regular road vehicles where the tax rates are higher. It is primarily intended for agricultural, horticultural, and construction vehicles, as well as for non-road mobile machinery such as tractors, excavators, cranes, and boats. This differentiation is crucial because red diesel is taxed at a significantly lower rate than the un-dyed diesel fuel used in road vehicles. The reduced tax levy is a form of subsidy to support these industries, which are often considered essential to the economy and society.
The marker dye used to color red diesel is not just a simple coloring agent; it has properties that make it detectable. In the event of misuse or misfuelling, the red color can be easily identified, and the dye can be detected chemically. This helps in enforcing the regulations and preventing tax evasion. The dye is designed to be stable under the conditions that diesel fuel is typically used, ensuring that it remains in the fuel and does not degrade or separate out.
It is important to note that the use of red diesel outside of its intended applications is illegal. The red color serves as a clear visual indicator that the fuel is not meant for use in regular road vehicles. If red diesel is found in a road vehicle's fuel tank, it can be a sign of tax evasion, which is a serious offense. The authorities have the means to detect the presence of the dye in fuel samples, and penalties for misuse can be severe.
The environmental impact of red diesel is also a consideration. While the dye itself is not particularly harmful, the misuse of red diesel can lead to environmental damage if it is spilled or leaked into the environment. The dye can contaminate soil and water, making it a concern for environmental protection agencies.
In terms of the chemical composition, red diesel is similar to regular diesel fuel, with the addition of the marker dye. It contains hydrocarbons, which are the primary components of diesel fuel, and it undergoes the same refining processes. The addition of the dye does not significantly alter the fuel's performance characteristics, such as its energy content, combustion properties, or lubricity.
To summarize, what makes red diesel red is the addition of a specific marker dye that is used for regulatory purposes. This dye serves to distinguish red diesel from regular diesel, allowing for a reduced tax rate on its use in designated applications. The dye is stable, detectable, and plays a crucial role in preventing tax evasion and supporting vital industries within the UK economy.

In the United Kingdom, "red diesel" is dyed gas oil for registered agricultural or construction vehicles such as tractors, excavators, cranes and some other non-road applications such as boats. Red diesel carries a significantly reduced tax levy compared to un-dyed diesel fuel used in ordinary road vehicles.
