I'm more looking for some 100 octane than anything higher. Just enough for some extra knock protection. I can't have anything leaded, since I have a cat still, and it also will destroy my O2 sensors (the front O2 is expensive).

Still haven't really found anything definitive. There's no Sunoco in this area (Lakeland or Sarasota are the closest) that sell their 100 octane, according to their website. I've been told of a station on Hercules in Clearwater, but haven't found exactly where its at, or what the station's name is, or what type of race gas they sell. I think I'm gonna call Automotive Engineering (across the street) and see if they know of anybody.

The tolulene is my last resort. And I guess I don't quite understand how high[er] octane can cause a lean condition.
