A few gas stations near here sell 103 or 108 octane race fuel. It was like $8 dollars last year so I can only imagine what it is now.In CA we only have 91 octane as our premium that is readily available. So I don't run anything less than that in my 6R.
As far as I am concerned, I run 91 usually. I notice small differences when I am cold starting the engine and need to run it.
