Around here 93 seems to be the labeled octane on all the "high-test"
pumps. It used to be that Sunoco Ultra was 94, but now it is also
listed as 93. I used to run Ultra all the time, but I can't say it
is any worse with the current 93's, maybe even better. Of course,
this area being in the (used-to-be-)snow-belt, it is flooded with
Subarus which require a high octane gas, so I've been told.

I believe the comp ratio was 9:1, compared to the traditional 7.5:1.
