Jet fuel in cars for speed increases
The idea of using jet fuel in cars for speed increases is a common fantasy among car enthusiasts. While it is technically possible to run a car on jet fuel, it is not recommended and may not provide the desired performance boost.
Jet fuel is a kerosene-based substance designed for use in jet engines, which function differently from piston engines in cars. Jet fuel has a high octane rating, which is a measure of stability. While high octane fuel can provide more power, it requires a high-compression engine to take advantage of it. Modern cars are not designed to run on jet fuel and may experience issues with their emissions systems due to the lead content in aviation fuel.
Some older cars with diesel engines can handle jet fuel, but it is not advisable due to the higher level of sulfur and other additives, such as cetane, which can damage the engine over time. Additionally, jet fuel does not lubricate as well as diesel fuel, so using it in a diesel car may require adding a lubrication additive.
While jet fuel may not provide a significant speed increase in a standard car, some car enthusiasts have experimented with mixing jet fuel with gasoline or using aviation gasoline (avgas) as a substitute for racing gas. Avgas has a very high octane rating, typically around 100, which can help prevent premature detonation (knock). However, avgas is less dense than regular gasoline and may require different carb or injector jettings.
In conclusion, while it is possible to run a car on jet fuel or avgas, it is not recommended for most drivers. The potential risks to the engine and emissions systems, as well as the lack of significant performance gains, make it a poor choice for anyone looking to increase their car's speed.

Jet fuel vs. aviation fuel
Jet fuel is a kerosene-based substance, while aviation fuel, or Avgas, is high-octane gasoline. Jet fuel has an octane rating of 40-50, which means that it will cause a modern car engine to knock and run poorly, or not at all. On the other hand, aviation fuel can be used in cars and will result in less pinging and knocking. However, aviation fuel will not improve performance unless the engine is designed to take advantage of it.
Aviation fuel, or Avgas, is also known as 100 low lead and contains lead in a concentration of approximately 0.5 g/L. The lead in Avgas can ruin oxygen sensors and catalytic converters, requiring expensive repairs. However, some older car engines are not picky about the type of fuel they use and can run on aviation fuel without issue.
Sustainable aviation fuel (SAF) is an alternative to traditional jet fuel that is made from non-petroleum feedstocks, such as used cooking oils, fats, plant oils, municipal solid waste, and forestry waste. SAF has the potential to reduce carbon emissions by up to 80% compared to traditional jet fuel. SAF can be blended with conventional jet fuel at different levels, with a maximum blend of 50% currently allowed for Airbus aircraft. However, by 2030, Airbus aims to have aircraft and helicopters capable of flying with 100% SAF.
The use of SAF is important for reducing the carbon footprint of the aviation industry, which is expected to double to over 8 billion passengers by 2050. SAF can be produced through various technology pathways, including hydroprocessed esters and fatty acids (HEFA) and alcohol-to-jet (AtJ) processes. ASTM International has approved eight technical pathways for producing SAF, and multiple federal agencies are working together to expand its consumption and reduce greenhouse gas emissions.

Jet fuel and engine compatibility
First, it is important to understand the differences between jet fuel and automotive fuel. Jet fuel, also known as Jet A, Jet A-1, or aviation turbine fuel, is a kerosene-based substance designed specifically for airplanes with gas turbine engines. It has a higher level of sulfur and other additives, such as cetane, than automotive diesel fuel. This difference in chemical composition can lead to issues when used in car engines, which are designed to run on fuel with significantly lower sulfur content.
When considering jet fuel and engine compatibility, it is crucial to distinguish between gasoline and diesel engines. Jet fuel is not suitable for gasoline engines due to its diesel-like properties. Gasoline engines rely on spark ignition, and jet fuel is not designed to be ignited in this manner. Using jet fuel in a gasoline engine will likely result in knocking and poor performance, if the engine runs at all.
However, jet fuel can be used in diesel engines with some success. Jet fuel is chemically similar to diesel fuel and kerosene, and some car owners have reported running jet fuel in their diesel cars without major issues. That being said, jet fuel does not provide the necessary lubrication for diesel engines, so additional lubrication additives may be required to prevent engine damage.
Additionally, the high lead content in some types of aviation fuel, such as avgas, can coat the catalysts in the emissions system, rendering the car inoperable and requiring costly repairs. The lead in avgas can also damage oxygen sensors, leading to frequent replacements.
In conclusion, while it is technically possible to run jet fuel in some car engines, particularly diesel engines, it is not advisable due to the potential for engine damage, decreased performance, and environmental concerns. Car engines are designed to run on fuel with specific properties, and using jet fuel can lead to costly repairs and may even void warranties. Therefore, it is best to use the fuel that is designed for your vehicle to ensure optimal performance and longevity.

Jet fuel and engine performance
The idea of using jet fuel in cars for additional performance has been a topic of fascination for many car enthusiasts. However, the reality is that jet fuel is not a magical solution for boosting car performance. Jet fuel is specifically designed for use in jet engines, which have different fuel requirements than piston engines found in most cars.
Jet fuel, also known as Aviation Turbine Fuel, is similar to kerosene or home heating oil. It has a high octane rating, which is a measure of stability, but this does not translate into increased power unless the engine is designed to take advantage of it. In a normal car, jet fuel would provide a more stable fuel source, resulting in less pinging and knocking. However, it is important to note that jet fuel is not suitable for use in gas-powered cars as it is similar to putting diesel in a gasoline engine.
While some older car engines can handle the leaded aviation fuel, it is not recommended due to potential negative impacts on the emissions system. The lead in aviation fuel can coat the catalysts, rendering them ineffective. Additionally, jet fuel has a higher level of sulfur and other additives than automotive fuel, which may damage the engine and even result in fines.
For those seeking enhanced performance, it is important to understand that increasing power requires more than just high-octane fuel. To utilize the stability of high-octane fuel, modifications are necessary to increase the compression psi in the cylinder, either through static or dynamic compression ratio adjustments. Simply using jet fuel in a standard car engine will not result in significant performance gains and may even lead to engine damage.
In conclusion, while jet fuel can be used in certain car engines, it is not a guaranteed way to improve performance. The stability and high octane of jet fuel do not automatically translate into increased power. Additionally, there are potential drawbacks, including emissions system issues and engine damage, which should be carefully considered before attempting to use jet fuel in a car.
