93 octane worth it?
Just curious if the 370z would run better/faster on 93 octane fuel. In nevada we only have 91 here but there is a place not to far from home that has 100. Figured I could occasionally mix the two to get roughly 93 octane if it was worth it. I know the STI's are meant to run on 93 so west coast STI's see slightly decreased performance due to 91 octane fuel. Just wondering if the Z is similar in that it would benefit from 93 or not. By the way this is in regards to stock trim. Thanks

93 isn't nessassary, don't waste your time looking for it. We have alot places with 93 around but I don't go out of my way to go find it. From 91 to 93, the increase in performance would be marginal at best. 91 will work fine in the Z.

I miss 93 octane. It definitely made a performance difference. In the 350Z (last car to try 93 octane), throttle response was awesome and it was easy to spin out of 2nd while making a turn. When the tank gets close to empty it starts feeling a tad weak until I fill it up again.
I wonder what it feels like with the 370Z. Anyhow, most of the gas stations here contain 10% Ethanol. |

Also, what you experienced with your 350z and 93 octane was placebo, short of you having done something to the engine to "require" it - such as an ECU tune. Bolt-ons will not change octane requirements, but forced induction may. My 370z, with it's 7AT, will roast 1st entirely, chirp 2nd pretty good, and sometimes chirp 3rd. I'ev also gotten it to trigger the slip light in 4th. All of that while going in a straight line. Knowing how quickly this car will whip around when it breaks traction while turning (VDC is a good thing...lol) - I don't try the whole "while turning" bit. If mine had an open diff, I might still be able to get away with powersliding and so on...but not with my Z's VSLD... |

cool guys. thanks

Fill up my Z with 91 or 93 but don't let me know.
$1000 says I can tell you the difference. |
unless you change your compression ratio you won't realize any advantages to higher octanes. Remember octane is not a measurement of energy potential -- it measures a fuel's resistance to premature detonation. Higher octanes mean you can safely compress the gas further. But you can't take advantage of that just by filling up with higher octane
