Jet fuel is not diesel fuel, JP5 is basically Kerosene.

Kerosene is diesel #1
Diesel #2 is what diesel cars and trucks run on. They will also run just fine on diesel #1.

Diesel oil would burn too slow to be used in a jet engine I would hazard a guess.

Diesel is dirtier than jet fuel but still usable as jet fuel if engine is derated by 10%.
