That may be true, but you try running 87 in your 370z and tell me how your engine runs after 2 years. If the manual recommends 91 or above then why go low octane? Like I said before, it doesn't feel more powerful, it just like the throttle is a bit more responsive. Plus, I'm not going to do all Race gas. I'm mainly going to do a blend of 100 plus 91 just because I don't believe in the bare minimum for my Z!
