Better? Bad? For V12's. new gas stations have. Only 90 octane??

We have no choice, they add it to the fuel by up to 10 or 20%. It is the Ethanol producer's Lobby that has mandated this. I have read that in older cars it corrodes various engine parts.

Ok,... everyone please understand, I have a few local stations here locally (Fort Myers /Naples to) who sell non ethanol fuel. For boats mainly. Its a little higher priced and only 90 octane.

My question is, it better for my car or is there a possibility it could hurt somethings?
My car calls for 91 octane.

I live in Naples and I tried half a tank in my S65. I was wondering about it too. I use it in my 1958. Any one know if it is good for our cars (S65)?
