What octane petrol can I use - V12 twin turbo
Hi - what octane petrol/gas do members use in their V12's (twin turbo) - it says 98 minimum, but in New Zealand most pumps are either 91 or 95 unleaded. There are some that offer 98 but these are rare. Do you use 95 octane petrol/gas???

US V-12's are supposed to have 91 minimum, but highest I can get at the pump is 90 and my car runs fine on that, even with my tune. However, it runs a lot stronger when I put in some 109 octane!

Do you guys in NZ use RON or octane? In the UK we use RON which is a middle ground, Ie 98 RON = 94 Octane in USA
