Incorrect. Most cars are fine on 87 octane, but some higher-performance cars with higher-compression engines really do need higher octane fuel. I don't know the percentages, otherwise I'd post an answer myself, but it's definitely more than 0%.

Agreed. Ditto those that use forced-induction like the WRX/STi, the Evo, the Mini Cooper S.....

For God's sake - take a joke!!

Personally, I have had a few cars that would not run on 87-octane without problems and the one car I had that lasted the longest got killed by it's new owner in short order in part because he ignored my warnings and ran 87-octane only. Pinging can kill, therefore I don't take it as a joke.
