I'm not in any way saying that I would run 85 octane in a Z or any high compression engine for that matter, but what I am saying is that if you accidently filled it up with a lower octane fuel your not going to cause damage.

Oh BTW, on page 9-3 it does state that you should not use gas containing lead in it, FYI most race gases have lead in them.

This is page 9-3 of the manual, I think you are reading a different manual than me, or you can't comprehend English.

FUEL RECOMMENDATION
VQ37VHR engine
Use unleaded premium gasoline with an octane
rating of at least 91 AKI (Anti-Knock Index)
number (Research octane number 96).
If premium gasoline is not available, unleaded
regular gasoline with an octane rating of 87 AKI
number (Research octane number 91) may be
temporarily used, but only under the following
precautions:
. Have the fuel tank filled only partially with
unleaded regular gasoline, and fill up with
unleaded premium gasoline as soon as
possible.
. Avoid full throttle driving and abrupt acceleration.
However, for maximum vehicle performance,
the use of unleaded premium
gasoline is recommended.
CAUTION
. Using a fuel other than that specified
could adversely affect the emission
control system, and may also
affect warranty coverage.
. Under no circumstances should a
leaded gasoline be used, because
this will damage the three-way catalyst.
. Do not use E-85 fuel in your vehicle.
Your vehicle is not designed to run
on E-85 fuel. Using E-85 fuel can
damage the fuel system components
and is not covered by the
NISSAN vehicle limited warranty
