2024 Telluride Gas

I recently noticed in the Telluride app that under the "maintenance" section, it states 91 octane is recommended. I was a little shocked since the Telluride V6 isn't a high compression / high performance engine. Internet searches indicate 87 octane is sufficient. In the 14 months I've owned the car I've always used 87 octane and occasionally a quality fuel system cleaner, and the car runs fine.

Has anybody else run different octanes and seen any effect on performance or reliability?
