370z requires premium fuel?

Crash

Nope. It just runs with fewer knocks.

100 octane is really meant for MUCH higher compression engines or forced induction.

But it would still be safe if you were to use it right?

Yes, it is safe. But not necessary on a naturally aspirated VQ unless you are tuned for it.

I have a 2006 G35 Coupe 6MT with a tune, and one of my maps is tuned for 100 octane. It does yield a few more hp and smoothens out my powerband, but its nothing like forced induction.

I only use my 100 octane performance map when I track the car. Mostly for additional safety since 100 octane would be less likely to knock.
