Red diesel and kerosene are two types of fuel commonly used in various applications. Understanding their differences, similarities, and proper uses is essential for making informed decisions about fuel usage.
What is Red Diesel?
Red diesel, also known as gas oil or marked diesel, is a type of diesel fuel. It is dyed red to indicate that it is a rebated fuel. This means it is subject to lower taxes compared to standard road diesel. Red diesel is primarily used in agricultural, construction, and industrial applications. It is not legal for use in vehicles that operate on public roads.
What is Kerosene?
Kerosene is a lighter petroleum product. It is often used as a fuel for jet engines, heating, and lamps. Kerosene is clear or slightly yellow and has a lower viscosity than red diesel. It can also serve as a solvent and is utilized in various industrial applications.
Key Differences Between Red Diesel and Kerosene
Composition: Red diesel has a higher cetane rating than kerosene. This affects combustion efficiency and engine performance.
Taxation: Red diesel is heavily taxed for use on public roads, while kerosene is generally used in applications where road taxes do not apply.
Usage Restrictions: Red diesel is restricted to specific sectors, while kerosene has a broader range of applications.
Can You Substitute Red Diesel for Kerosene?
Using red diesel instead of kerosene can have significant implications. It is crucial to consider the intended use before making a substitution.
Legal Considerations
Using red diesel in applications designed for kerosene is generally illegal in many jurisdictions. This is because red diesel is taxed differently. If caught using red diesel in a vehicle that operates on public roads, penalties can be severe.
Performance and Compatibility
Engine Compatibility:
Engines designed for kerosene may not operate optimally with red diesel. The higher viscosity of red diesel can cause issues in fuel injection systems designed for the lighter kerosene.
Red diesel burns differently, affecting combustion efficiency and power output.
Burning Characteristics:
Kerosene has a lower boiling point than red diesel. This means kerosene vaporizes more easily, which can be critical for certain applications, such as heating.
Emissions:
The combustion characteristics of red diesel lead to different emissions profiles compared to kerosene. This can be a concern for regulatory compliance in certain applications.
Applications of Red Diesel
Red diesel is commonly used in specific industries. Here are some primary applications:
Agricultural Use
Farm machinery often uses red diesel due to its lower tax rates. Tractors, combines, and other agricultural vehicles benefit from the fuel’s higher energy content.
Construction Industry
Construction equipment, such as excavators and bulldozers, typically runs on red diesel. The cost savings from using this fuel can be significant for construction companies.
Industrial Applications
Many industries use red diesel for stationary engines and generators. Its cost-effectiveness makes it a popular choice for powering equipment in various settings.
Applications of Kerosene
Kerosene is used in different sectors, mainly for:
Aviation Fuel
Jet fuel is a type of kerosene. It powers commercial and military aircraft. Kerosene’s characteristics make it suitable for high-altitude flights.
Heating
Kerosene is commonly used for heating homes and buildings. It is often found in areas where natural gas is unavailable.

Lamps and Stoves
Kerosene can also fuel lamps and stoves in areas without electricity. Its ability to burn cleanly makes it a preferred choice for such applications.
Considerations for Substitution
When considering using red diesel instead of kerosene, several factors should be evaluated:
Cost
While red diesel is generally cheaper due to lower taxes, the total cost of ownership should include potential engine modifications and repairs. If switching fuels leads to increased maintenance, savings may diminish.
Availability
In some regions, kerosene may be more readily available than red diesel. Consideration of local fuel supply chains is essential.
Environmental Regulations
Different fuels have varying emissions standards. Ensure compliance with local regulations before making any substitutions.
Conclusion
In summary, while it might be tempting to use red diesel instead of kerosene, it is crucial to understand the legal, performance, and compatibility issues involved. The two fuels serve different purposes and are subject to different regulations.
Using red diesel in place of kerosene can lead to legal repercussions, engine performance issues, and potential compliance violations. Before making any fuel choices, it is advisable to consult with fuel experts or regulatory agencies.
In most cases, it is best to use each fuel for its intended purpose to ensure optimal performance and compliance with laws and regulations. Always consider the specific requirements of your equipment and the legal ramifications of fuel use in your area.
FAQs
Does Diesel Burn as Clean as Kerosene?
No, diesel generally does not burn as clean as kerosene. Kerosene is a lighter fuel with lower levels of impurities, which leads to cleaner combustion and fewer emissions. Diesel, particularly red diesel, tends to produce more soot, sulfur compounds, and particulate matter during combustion. This is especially true in applications where proper air-fuel mixing isn’t optimal. Kerosene’s cleaner burn is why it is often used in heating systems and aviation, where cleaner exhaust is important.
Will Red Diesel Damage My Engine?
Red diesel will not damage your engine if the engine is designed to run on diesel fuel. However, if your engine is designed for kerosene, using red diesel could lead to problems. Red diesel has a higher viscosity and different combustion characteristics, which can cause issues such as incomplete combustion, clogged injectors, or excessive carbon buildup. Always check the manufacturer’s recommendations for fuel types to avoid engine damage.
Is Red Diesel Heavier Than Kerosene?
Yes, red diesel is heavier than kerosene. Red diesel has a higher density and viscosity compared to kerosene, which is a lighter and more refined fuel. This difference in weight affects how the fuels flow and burn. For instance, kerosene vaporizes more easily than diesel, which contributes to its cleaner combustion.
