The octane ratings of AVGAS, a gasoline-based fuel, are usually either 91 or 100 (lean mixture) and 96 or 130 (rich mixture). The octane rating of jet fuel is much lower, around 15 – this is much more like automotive diesel and thus much more resistant to detonating due to sparks or compression.

What octane level is aviation fuel?
The Lean Mixture rating is 100 octane (15 octane higher than the comparable 85 MON for unleaded Mogas) but Avgas also has a Rich Mixture rating of 130 which allows higher supercharger boost pressures to be used without detonation occurring.
What octane is avgas 100LL?
100LL has a minimum MON of 99.6. AKI is the octane rating used to grade all U.S. automotive gasoline (typical values at the pump can include 87, 89, 91, and 93), and also the 93UL fuel from Airworthy AutoGas. The minimum AKI of UL94, as sold by Swift Fuels, is 98.0.
What octane is Jet A1?
Most jet fuel (Jet A, Jet A1, JP-5, JP-8, TS-1) is kerosene based and kerosene has an octane rating of 15. Some jet fuel (Jet B and JP-4) is naphtha based and naphtha has an octane rating of around 60.
What is octane fluid?
Octane is a straight chain alkane composed of 8 carbon atoms. ... N-octane is a colorless liquid with an odor of gasoline. Less dense than water and insoluble in water.
What fuel do commercial airplanes use?
Aviation kerosene is the fuel of choice for aircraft across the globe.
Why is avgas 100 octane?
The most common avgas is 100 octane, which is a measure of the fuel's ability to resist premature detonation or "knock." Avgas is also available at other octanes such as 87 and 130, but they are rare today. ... It is generally safe to operate engines with a higher octane fuel than required, but not lower.
What is the octane rating of methanol?
Methanol reported as having an octane rating of 133 (RON) and 105 (MON), with a combined octane rating of 119 ((R+M)/2). In contrast the combined octane rating of regular gasoline is 87 and that of premium gasoline is 93.
Can you use avgas in a motorcycle?
AvGas is suitable for certain engines, namely ones that do not contain oxygen sensors or catalytic converters. It also is alright to use in dirt bikes that are rebuilt frequently, because the build-up of lead is not a problem.
What is the octane of diesel?
Diesel fuel has an octane rating of 25-40. Mixing 2% diesel fuel into gasoline will lower the overall octane rating by 1 point.
Can I put jet fuel in my car?
Jet fuel can actually be used in cars, but only in diesel engines. Kerosene jet fuel and diesel are actually similar enough to allow for cross-functionality and would provide a similar performance. ... Both are derived from crude oil, and both run their respective engines on combustion.
What is the octane of kerosene?
Generally, the octane number (ON) of gasoline is in the range of 70–97, whereas the octane number of kerosene is much lower as only 20–50.
What is octane number and cetane number?
The main difference between cetane and octane ratings is that the octane rating represents how well a fuel can resist pre-ignition due to compression—ensuring the fuel ignites only from a spark from the spark plug. However, the cetane number measures the delay in the ignition time of the fuel.
What is knocking and octane number?
Octane number is also known as octane rating. Octane numbers are based on a scale on which isooctane is 100 (minimal knock) and heptane is 0 (bad knock). The higher the octane number, the more compression required for fuel ignition. Fuels with high octane numbers are used in high performance gasoline engines.
Can I use 92 octane instead of 95?
Generally speaking, there isn't an issue with using petrol with a higher octane rating. ... Using lower octane petrol (92) in a car designed for higher octane petrol (95) is potentially destructive. It's likely you'll lose some power, acceleration and fuel economy.
