87... too high, you can melt the head, from what i understand...

cool we've been using 87 since we bought the car, but some people says we could use 89 or 93 instead.

I'm sure you probably could use higher oct. fuels. I just don't know that you'd be buying yourself anything. The way it was explained to me (back many moons) was the higher compression engines should use higher octane because it could burn hotter... or something. I just remember being told I was gonna melt the head on my honda... and it came with a nice explanation. I nodded and smiled, and decided to switch to low grade. :D

hmm.. poking around, i found this...
