I read page 9-3 and no where did it state that running a lower octane fuel would hurt the engine. Like I said previously it will not hurt the engine because the ECU won't let it hurt the engine.

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.
