Hi All
I bought my mint STI just over a week ago and have been told that it has been mapped for Optimax/V power , its a 1998 STI S plate runing 320 BHP with full decat , can I use SUL 98 Ron or should I stick to 99Ron and above ????? I have been using V power from shell but thought I would ask the question due to the recent petrol price reductions ..... some feedback would be appreciated ...
