I used to only use 91 octane in my vehicles because I was always told it was the better choice for my engine. But then I saw this video from Consumer Reports and it was pretty eye opening. Now I primarily use 87 octane, unless premium is required.
For the Telluride I can't see there being much of a performance difference based on the type of fuel. It would be an interesting test though.
