I average 35-40 on my '02 at an average speed of 75+ including throttle happy moments. 
I have always use the higher octaine but have been contemplating lowering it to 87. Any one ever have issues doing this? As far as I know it timing has never been advace to merit the higher octaine, it is just how I have always taken care of her.
