We had a scooter (J-52 powered A-4) fueled with diesel in California from a fuel truck with the wrong load that ended up flying back to ABQ. No one had a clue until fuel samples were taken at home plate following the next fueling.
Corrective action was to completely drain and refuel with JP-4-- so it appears that the engines don't really see much difference.
Good thing he didn't encounter fuel freezing.
With a single stovepipe, that wouldn't be good.
