Airplane fuel, also known as jet fuel, aviation fuel, or avgas, is used to power aircraft engines. It is a type of fuel specifically designed for use in airplanes, and its properties differ from those of regular automotive gasoline or diesel fuel. Jet fuel is typically kerosene-based, with a higher flashpoint and a lower freezing point than gasoline, making it suitable for the cold temperatures experienced at high altitudes. While jet fuel is stable and less volatile than gasoline, the question remains: can it be used in cars?

What You'll Learn
Jet fuel is stable and less volatile than gasoline
Jet fuel is denser and heavier than gasoline. It is made up of longer chains of hydrocarbon atoms, with 12 to 15 atoms, compared to gasoline's 7 to 11 atoms. This difference in molecular structure contributes to jet fuel's stability and lower volatility.
The stability of jet fuel is further enhanced by its high flash point, which is the temperature at which it can ignite. Jet fuel has a higher flash point than aviation gasoline, making it less likely to ignite accidentally. This characteristic is particularly important for aviation safety, as it reduces the risk of combustion during fuel handling and storage.
Additionally, jet fuel has a very low freezing point, typically around -60°C. This property is essential for aircraft operating in extremely cold environments, such as in northern Canada and Alaska. The low freezing point of jet fuel helps to maintain its stability and fluidity even at high altitudes, where temperatures can drop significantly.
In contrast, gasoline is lighter, less dense, and more volatile than jet fuel. Gasoline has a lower flash point, making it more flammable and easier to ignite. When sprayed into a cylinder, gasoline immediately starts to vaporize, and the spark plug's fire causes it to detonate and power the engine. This quality makes gasoline well-suited for use in cars, where ease of ignition is crucial for engine performance and efficiency.
While jet fuel is less volatile than gasoline, it is still highly combustible. Its combustion properties are carefully regulated by organizations such as ASTM International and the U.S. Department of Defense to ensure its safe and efficient use in aircraft engines.

Jet fuel is similar to diesel but with fewer lubricating oils
Jet fuel is similar to diesel fuel but with some key differences. Jet fuel is often used in diesel-powered ground-support vehicles at airports. However, jet fuel has poorer lubricating abilities compared to diesel, which can increase wear and tear on fuel injection equipment. This is because jet fuel is "dry", lacking the additives mixed into diesel fuel to lubricate the injector system.
To compensate for the lack of lubricity, an additive may be required. Some people add a cup of Marvel Mystery Oil to each tank when using jet fuel to improve lubricity. Jet fuel contains more sulfur, up to 1000 ppm, which gives it better lubricity and means it does not currently require a lubricity additive, unlike pipeline diesel fuels.
The viscosity specifications of the two fuels also differ. Jet fuel tends to have a lower viscosity than diesel, which can cause long-term wear on pumps and injectors. Jet fuel is also closer in composition to kerosene, while diesel is heavier and has a higher lubricity.
While jet fuel can technically be used in some diesel engines, it is not recommended for newer engines as it can cause issues such as clogged injectors. It may be more suitable for older engines, such as the Cummins B-series, which have been known to run on jet fuel without issues.
Overall, while jet fuel and diesel have some similarities, the differences in lubricity, viscosity, and composition mean that jet fuel is not always a suitable substitute for diesel in cars and can cause increased wear and tear on engine components.

Avgas is 100 octane leaded gasoline
Avgas, or aviation gasoline, is used in piston-engine aircraft. It is leaded gasoline with a 100 octane rating. Avgas 100, as it is also known, is a high-lead fuel used in high-performance aircraft. The high octane rating is achieved by the addition of tetraethyl lead (TEL), a toxic substance that boosts the octane rating and prevents engine knocks in high-performance aircraft. TEL is also a great antiknock agent, allowing higher compression ratios in the cylinder for greater efficiency and power.
The use of lead in avgas is a concern due to its known hazardous effects on health and the environment. Government agencies have been working on replacements for leaded avgas, and the aviation industry is slowly making steps to transition to more environmentally friendly and healthier fuels. However, as of 2024, the annual US usage of avgas was 180 million US gallons, most of which contained lead, and 170,000 aircraft in the US used leaded avgas. In Europe, avgas remains the most common piston-engine fuel.
Leaded avgas is available in several grades with differing maximum lead concentrations. The most common type of avgas for general aviation is 100LL, which has a lower lead content than Avgas 100 while still maintaining the required octane rating for most piston-engine aircraft. The "100" in 100LL represents the octane rating of 100, while "LL" stands for Low Lead. Regulations allow for a maximum lead content in 100LL of 0.56 grams of lead per liter of fuel.
Avgas 100 has largely been replaced by Avgas 100LL, but it can still be found at some airports. Avgas 80, a low-octane fuel used in older, low-compression piston engines, has also been mostly phased out, with most aircraft transitioning to Avgas 100LL. Avgas 100 is dyed green to make it easily identifiable.

Kerosene is cheaper to produce than gasoline
Kerosene, which is used in jet fuel, is cheaper to produce than gasoline. Kerosene is a composition of hydrocarbon chains that typically contain 12 to 15 carbon atoms. It has a higher boiling point than gasoline and does not evaporate under normal temperature conditions, which means it can be stored for a long time.
Gasoline, on the other hand, is composed of chains with 7 to 11 carbon atoms. These chains vaporize at temperatures below the boiling point of water, which is why spilled gasoline evaporates so quickly. Gasoline is extremely flammable, with a flashpoint of -40 degrees Fahrenheit, while kerosene is much less volatile, with a flashpoint of 100 degrees Fahrenheit.
Kerosene's lower volatility and longer storage life may contribute to it being cheaper to produce than gasoline. Additionally, kerosene does not have the same taxes as gasoline, which may also factor into its lower production costs.
However, it is worth noting that kerosene contributes to greenhouse gas emissions and is a non-renewable resource, which means it cannot be reused or recycled. Despite being cheaper to produce, kerosene may be more expensive to purchase due to its specialty and low sales volume.

Automotive gasoline is not a fully viable replacement for avgas
Secondly, while some lower-powered aviation engines can run on unleaded fuel, many high-performance and/or turbocharged airplane engines require 100 octane fuel, and modifications would be necessary to use lower-octane automotive gasoline. Additionally, automotive gasoline does not have the same quality tracking as aviation gasoline, which could impact the performance and safety of the aircraft.
Furthermore, ethanol-treated automotive gasoline is susceptible to phase separation due to altitude and temperature changes during flight. This can lead to water flooding the fuel system, causing in-flight engine failure, and the remaining portions of fuel may not meet octane requirements.
Lastly, while it is possible to use avgas in older cars without a catalytic converter, it will ruin the catalytic converter in modern cars. Therefore, while automotive gasoline may be used in some aircraft, it is not a fully viable replacement for avgas due to the specific requirements and operating conditions of aircraft engines.
