Jet Fuel

On another forum, one man who served in the military said that jet fuel is actually just kerosene. Is that really true?

JP-4

JP-8

There’s been several different blends used some have gas and other additives mixed in to avoid corrosion and icing etc.

A quick google suggests that jet fuel is a highly refined variant of Kerosene. Probably similar to the difference between regular and high octane gasoline

Yes, Avtur is basically kerosene with additives to stop icing and other stuff that grows in it. Gasoline/petrol would melt a gas turbine engine.
