I don't know which part of Italy you are but Gas there is similar or better than here.
The Standard one should be 95-96 octane (US 93 Ron) and it should be easy to find the 98+
I'm in CA now and the maximum I have is 91 Ron with 10% of Ethanol.
(By the way, if you are near Rome, let me know, I can give you some tips to find good specialists in US cars)
