100 octane C300 V6 2012
So there's a gas station not too far away from me and it has 100 octane fuel. I was thinking of putting a 1/4 to a 1/2 tank in, mixing it with the 93 I have in now. I have a few questions before I do this because I am afraid this may have some adverse affects.
Is it worth it?
Final question will it set off any codes/faults that will give me an emission warning/ or set off my O2 sensor?
I drive a 12' C300 with the 3.0 V6 (W204)

I think it would be a waste of money.
The reason for specifying a minimum octane value is to assure that there is neither pre-ignition (bad for engine), nor a timing adjustment to prevent pre-ignition (bad for performance).
Once ignition occurs, it doesn't matter how much reserve octane your fuel has, the deed is done.
I'm no automotive engineer so if I'm wrong, don't hesitate to say so.

You are quite right here with your thoughts.
The higher octane is a waste of money since you will not be racing, you do not have a turbo or super charges or a highly tuned natural aspirated engine with after market ECU specs.
Here they sell octane 94 which in turn is high enough for street cars.
Besides higher octane does not mean cleaner burn. If the high octane fuel is low on detergents then it will still leave carbon deposit build up.
Hope that helps.
