I did european delivery and I spoke with both my delivery agent and the paperwork agent on petrol and they both had the same speech: don't bother buying more than 91 as the engine won't know the difference and it'll be a waste of money.
I don't know enough to have an opinion on it and can only buy 91 here anyway, but that's what they said.[/QUOTE]
Oh, I think it's more powerful using 93. I will try 91 next time. THX
