Red,
Since you are relatively new to the club, I will tell you that has been discussed many times. With aluminium heads and just 9.7:1 compression you should be able to run this crap we get here that they laughingly call premium. I have 11:1 in both of my cars and I have ran them on this junk when I was out and couldn't get anything to mix with it. I normally mix 110 octane leaded racing gas in mine and that works great.
