It is possible to run a diesel engine on jet fuel, but it is not recommended. Jet fuel lacks the lubricants found in diesel fuel, which can cause long-term damage to the engine. Older diesel engines are better suited to running on jet fuel, as they have inline injection pumps that can better cope with fuel that doesn't meet diesel parameters. Modern diesel engines have stricter requirements for fuel viscosity and sulphur content, which jet fuel may not meet.

What You'll Learn
Jet fuel lacks lubricants, which are found in diesel fuel
Jet fuel can be used in diesel engines, but it lacks some of the lubricants found in diesel fuel. Jet fuel has a higher flashpoint and a lower freezing point than gasoline, which is similar to diesel fuel. However, jet fuel has poor lubricating abilities in comparison to diesel fuel, which can increase wear and tear on fuel injection equipment. This means that an additive may be required to restore its lubricity.
Lubricity additives have been used in diesel fuels for many years to reduce wear on engine components. The use of these additives has now become a requirement in most diesel fuels to meet global specifications. The performance of the fuel is determined using the high-frequency reciprocating rig (HFRR) test, which measures the diameter of the flattening of a ball after the test. A lower result indicates better performance.
The careful selection of lubricity additives is crucial, especially when blending diesel and jet fuel. The increased amount of cetane improver required to maintain the cetane number can also impact the lubricity of the final diesel-jet fuel blend. To ensure the blend meets the required specifications, refiners and blenders must assess the performance of these new blends and revise additive treatments.
While jet fuel lacks the lubricants found in diesel fuel, it can still be used in diesel engines with the addition of lubricity additives. However, it is important to note that this practice may not be suitable for modern vehicles, as adding most oils can create soot that will block the DPF. Overall, while jet fuel can be used in diesel engines, it requires careful consideration and the addition of additives to compensate for its lack of lubricants.

Jet fuel has a higher flashpoint and a lower freezing point than diesel
Jet fuel is also known for its low freezing point, with Jet A specification fuel having a freezing point of -60°C. This is much lower than diesel fuel, which typically freezes at around -10°C. The low freezing point of jet fuel is necessary for use in extremely cold environments, such as northern Canada and Alaska.
The higher flashpoint of jet fuel makes it less flammable than diesel fuel, which contributes to its safety during transportation and handling. Turbine engines, such as those found in diesel vehicles, can operate with a wide range of fuels, including jet fuel. However, jet fuel lacks some of the lubricants found in road diesel fuel, so the addition of a lubricity additive may be necessary when using jet fuel in a diesel engine.
Some people have successfully run jet fuel in their diesel vehicles for extended periods without issues, especially in older vehicles. However, it is not recommended for use in modern vehicles, as the addition of oils can create soot that blocks the DPF/SCR. Overall, while jet fuel can technically be used in a diesel engine, it may not be advisable due to potential compatibility issues and the need for additives.

Jet fuel is denser than diesel fuel
Jet fuel and diesel fuel have a lot in common. Historically, jet fuel and diesel were quite similar in extraction, production, composition, and application. However, jet fuel is denser than diesel fuel. This is important because it means that water contamination can be identified and removed. During flight, the temperature of the jet fuel in the tanks decreases, causing the precipitation of water, which is denser than jet fuel. This water can then be removed to prevent it from freezing and blocking fuel inlet pipes.
Jet fuel is also defined as a performance specification rather than a chemical compound. The range of molecular mass between hydrocarbons is defined by the requirements for the product, such as the freezing point or smoke point. Kerosene-type jet fuel has a carbon number distribution between about 8 and 16 carbon atoms per molecule, while wide-cut or naphtha-type jet fuel has a range of about 5 to 15.
In terms of practical use, jet fuel has been used in diesel engines, particularly older ones. Some people have run jet fuel in their diesel vehicles for years without issue, but it is not recommended for modern vehicles. Jet fuel lacks some of the lubricants found in diesel fuel, so an additive may be required to restore its lubricity and prevent increased wear in fuel injection equipment. Additionally, jet fuel has a higher freezing point, which can be hazardous at high altitudes.
Overall, while jet fuel is denser than diesel fuel and there are some similarities between the two, there are also important differences to consider when using jet fuel in a diesel engine.

Modern diesel engines may not be compatible with jet fuel
Diesel fuels are rated in cetane, which is a measurement of the ignition quality of the fuel. Jet fuel is not rated for cetane and typically has a lower cetane rating than standard diesel fuel. Jet fuel also has a higher level of sulfur than is allowed in diesel fuel, which may cause damage to the engine.
Modern diesel engines have higher injection pressures than older engines, which means that the fuel must be within a narrow range of parameters set for the fuel, or the injection pump will suffer damage. These electronic systems often have sensors measuring fuel viscosity, and any variation from the fuel parameters set by the engineers means the ECU won't fire the injectors. Newer diesel engines also require ultra-low sulfur fuel, as high-sulfur fuel can damage sensitive pollution control devices.
While jet fuel may work in older diesel engines, it is not recommended for use in modern diesel engines due to the potential for long-term damage to the engine. It is always best to use the fuel that is made for your vehicle.

Using jet fuel in a diesel engine could lead to fines and engine damage
Jet fuel can be used in diesel engines, but it is not recommended. While some older diesel engines can handle jet fuel, it is not designed for use in cars and there are key differences between the two fuels. For example, jet fuel has a higher level of sulfur and other additives, including cetane, than diesel fuel. As such, using jet fuel in a diesel engine could result in fines and engine damage.
Firstly, jet fuel lacks some of the lubricants found in diesel fuel. This means that using jet fuel in a common rail diesel engine will require a specific lubricity additive. Without this, jet fuel can destroy the DPF/SCR of a diesel engine.
Secondly, jet fuel has a higher level of sulfur than diesel fuel. This means that jet fuel has a higher level of emissions than diesel fuel, which could result in fines for the driver.
Thirdly, jet fuel has a higher flashpoint than diesel fuel. This means that jet fuel is more likely to ignite than diesel fuel, which could result in engine damage.
Finally, jet fuel has a lower freezing point than diesel fuel. This means that jet fuel is more likely to freeze in the filters, which could result in engine damage.
In conclusion, while jet fuel can be used in diesel engines, it is not recommended due to the risk of fines and engine damage. It is always best to use the fuel that is made for your vehicle.
