98 ron only. Optimax all the way for me.

 

why? are you posting from a petrol station, pump in hand? LOL

i would say always run it on optimax (98 RON) or tesco 99 RON.

if you need to put in 97 RON SUL

only in emergencies use 95 RON (normal)

the price difference is not so great that its worth using lower grade fuel which (can) do a bit or damage, but most importantly will reduce performance (and you certainly have a performance car)

my boss runs his Ferrari 360 on UL & SUL about 3:1, and says its fine. i think its just a pretty stupid thing to do

 

dont worry - just found info on prodrive site

for the record - doesnt need it - but they recommend best perf with it !
