93 octane worth it?

From 87 to 93, definitely!; from 91 to 93...?

93 is all we get around here for super unleaded... So that's what I use in my Z.

there are noticeable differences between fuels but usually only if you are comparing a good premium to a lesser grade fuel even of the same octane. It's more about the gas than it is the octane number.

as for the JP-5 apparently it is the naval standard for at sea operations so every plane on an aircraft carrier uses it

Makes sense - its high flashpoint is crucial to...oh, I dont know...not killing the crew if it ignites, and its extremely low freezing point is crucial to the U2's ability to fly extremely high without its fuel freezing.
