Jet fuel does not have an octane rating. Octane is a measure used for spark-ignition piston engines, while jet engines run on continuous combustion in a turbine cycle, so the octane concept isn’t applicable to Jet-A, Jet-A1, or JP-8 fuels. In practice, aviation fuel quality focuses on properties like energy content, density, viscosity, flash point, freezing point, and additives, not octane number. For up-to-date context, sources emphasize that octane ratings are irrelevant for turbine fuels. If you’d like, I can pull a few recent articles that explain this distinction in more detail.[1][2][4]
Availability of octane-boosting blendstocks could drive the US toluene and mixed xylenes (MX) market in early 2020 as new bunker fuel regulations affect global refinery operations.

www.spglobal.comDifferent jet fuel types serve different purposes. Let's discover in detail what they are.
simpleflying.comThe antiknock rating of a fuel, commonly associated with gasoline used in piston engine vehicles, is not directly applicable to turbine engine fuels. Turbine engines, unlike piston engines, operate on a continuous combustion process. Therefore, the measurement of a fuel's resistance to detonation, as indicated by octane number, is not a primary consideration for jet propulsion.
signup.repreve.comSaudi Aramco announced the launch of a new high-octane gasoline grade, marking the first time Octane 98 fuel will be available in the Saudi market. The product is set to debut in January 2026, expanding fuel options for owners of sports cars and high-performance vehicles.
see.newsNew studies were performed at ORNL and NREL to further investigate the relationship between HoV and octane sensitivity. Three fuels were formulated for the ORNL study with matched RON and octane sensitivity, but with differing HoV. Experiments with these fuels in a 1.6-liter GTDI engine showed that the fuels exhibited very similar combustion phasing under knock-limited spark advance (KLSA) conditions. … Environmental Protection Agency (EPA) suggest the potential of a new high octane fuel (HOF)...
www.science.govExplores the concept of octane rating in fuels, differentiating between aviation gasoline (avgas) for piston engines and the kerosene-based fuels used in jet engines, clarifying that jet fuel does not have an octane rating.
