Default [ASKED] 17 z06 running on 91 octane

Tadge I have a 17 z06 and live in las vegas. I use chevron and the highest octane I can find is 91at any brand name gas. The local chev dealer told me 91 is fine I have read that the 17 z06 is tuned different than a 15or16 and that's why the owners states 93. I have called GM and was told it will have a slight impact on performance. What I am concerned about is the effect on engine life and no one has answered that question for me .. My z06 is driven on the street only and used for long trips Engine longevity is important to me Thanks PS this is my 5th corvette and second z06
