Still, 93 IS better than 91 in all condition, so far. (I'd bet that the guys up at 7000 to 10000 ft are better off with 91 octane.
There used to be some 93 octane available here. I'm going to start looking again.

There's a place 5 minutes away from me that sells 108 octane. I wonder how much I'd have to mix in a tank of 93 to get it up to about 97 octane or so... The stuff is close to $10 a gallon.
