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]

www.spglobal.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.

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)...
