Essential Things You Need to Know: What Is Red Diesel?


As gas prices continue to rise, it is essential to know the fuel we use to power our cars. Knowing the basics of how gasoline and fuel works can help you save money and understand how to best maintain your vehicle. Here are some tips to help you become more informed about gas and fuel.

In today’s article, let’s take a closer look at red diesel. What is it? Here’s what you need to know:

What to Know about Gas and Fuel

First, it is important to understand the different types of fuel available. Either regular or premium gasoline powers most cars. 

Regular gasoline is the lowest octane grade and is typically the least expensive. Premium gasoline is a higher octane grade and is generally more costly. Knowing which type of fuel is best for your vehicle will help you save money at the pump.

Second, there are different additives and detergents in gasoline. These additives can help improve the performance of your vehicle, as well as make it more fuel-efficient. It is important to use the right fuel for your car and ensure the fuel you use has the right additives.

Third, there is a difference between gasoline and diesel fuel. Diesel fuel is typically more expensive than gasoline but also more efficient. Diesel engines are designed to run on diesel fuel, so it is important to make sure you are using the right type of fuel for your vehicle.

What Is Red Diesel?

Red diesel, also known as gas oil, is used primarily in off-road vehicles, such as tractors, agricultural and construction equipment, and boats. It is also widely used in some power generation plants. Red diesel is unsuitable for vehicles that drive on public roads, as it contains a different level of taxation than regular diesel fuel. 

It is commonly coloured with a red dye to differentiate it from regular diesel. This colouring helps prevent the fuel from being used in vehicles meant to drive on public roads. 

In the United Kingdom, the red diesel is coloured with a red dye called Solvent Red 164, while in other parts of Europe, the dye used is Solvent Red 26.

Red Diesel vs Regular Diesel

The main difference between red diesel and regular diesel is the taxation. Regular diesel is subject to a higher level of taxation than red diesel, so it is cheaper for off-road vehicles to use red diesel. The lower taxation also encourages people to use red diesel for off-road applications, which is more economical than regular diesel. 

In addition to the lower taxation, red diesel has some other advantages over regular diesel. It has a higher cetane rating, which means it has a higher combustion efficiency and produces less smoke. It also has better lubricity, which means it does not cause as much wear on the engine components. 

For these reasons, red diesel is the preferred fuel for off-road vehicles, as it is more economical and performs better. However, it is essential to remember that red diesel is unsuitable for vehicles that drive on public roads, as it does not contain the same level of taxation as regular diesel fuel.

The Bottom Line

Red diesel is a valuable fuel for a variety of applications. It is both cost-efficient and produces fewer emissions than other fuel types. Its low sulfur content also reduces the pollution produced in the burning process. 

In addition, it is a reliable source of energy for off-road vehicles, construction equipment, agricultural machinery, and even marine vessels. Red diesel has proven to be an invaluable resource for many industries, providing a reliable and cost-effective source of power.
