100 octane on a basically stock naturally aspirated vehicle? worthless.
heavily modified turbo cars with no cats can run leaded fuel with no problems. even O2 sensors can take the lead for a little while. OBD2 cars will throw a code a lot more quickly though. Lots of heavily modified cars run without O2 sensors though.

have posted this before but will post it again.
Back in the 60's, Curtis Wright where bench testing their own rotary engines for different fuel applications.
They tested their own RC2-60 engine with fuels rated from practically Kerosene to 102 Octane.
They found that from around 87 - 102 Octane showed a less than 2hp difference after resetting the carby jets for the correct fuel mix.. A piston engine would have pinged & died
I suspect the RC2-60 engines had a compression ratio of around 9.0:1 being the 60's but the theory still stands for the todays "Atmo" rotary engines.
Thats why I will only ever use the cheaper stuff in the RX-8 as the only difference is felt in the wallet.

COME ON PEOPLE!! Has no one ever heard of Mr. Pillowpants???? The troll that lives in your car's gas tank and will bite off the fuel pump nozzle if you try to fill up with anything less than 100 octane!! The little bugger almost took off a couple of my fingers last time I tried!!! I am not trying that again....
And don't even get me started on Listerfiend... Don't you dare put synth oil in her!
