I know that all makes sense to you all, but because I really don't know that much about cars at altitude(or sea level for that matter) I can only relate back to my plane which is probably operated at twice the altitude as the normal high altitude car. When I am at 14,000 lets say, I am getting the same octane that the engine was designed for(100LL) whether it's at sea level or not. Because the air is thinner the higher I go I have a mixture control that lessens the amount of fuel going into the engine, but at no time does it change the octane rating. Sorry for the hijacking by the way...
