What will 100 octane gas do?

Yes this is true. I think our ECU can compensate till 95-96 Octane.

Here'a a mixture of 91 Octane and 100 Octane to get your desired octane mixture that I received from Unocal several years ago.

Well I've run my tank to about half full now and will stop by that station to fill it up with the "good stuff" for the weekend! We'll see how it goes! Hehe... Thanks for input fellas!
