No. It doesn't. If high octane gas makes your car faster, you have a problem with carbon buildup artificially raising your engine's compression and creating hotspots in your cylinders.
I know for a fact my car will run like crap on anything lower than 91. It explicitly states this on the fuel door itself, and several places in the manual. Turbo + 87 = bad performance and lower gas mileage. Possible engine damage is also a factor.
^^^To add to that, higher octane gas generally has less energy upon ignition. Thus you get less power (sometimes noticeably) in cars that weren't designed to NEED higher octane for safety (turbo cars, supercharged cars, and high compression motors).
Mythbusters used Ford suvs and rolled down all of the windows. So the results should not apply to a sedan or compact with only 1 or 2 windows rolled down because bodies, ride height, and interior space are completely different.
You are absolutely dead-on correct! The reason for the colder-humid climate and not being able to start your car is in my response to the article just below your's. The 87 will burn immediate since it has a shorter carbon chain than the 93. This is why Pentane and Hexane come with warning labels that would make hairspray envious! Not only does it burn quickly, very hot, and mostly without smell, but you can't really see the flame either! lolTurns out most of the people replying to that bulls**t article on Digg are sharper than the people graduating from UTI! Go Diggers!

I'm sure he means stale air vs fresh air.
