While I'm no expert, I've read a good bit on the subject ... I couldn't have said it better myself.
A few weeks ago, I was driving through rural Ohio at night and came across a gas station that only had 87. Each pump had three nozzles, but every single nozzle was labeled "regular" and "87". I was not pleased. I always choose the highest octane rating available (well, not Sunoco Racing Fuels). My understand is some pre-detonation is audible, other pre-detonation is not, so I don't rely on the noises I hear.
