Is Optimax crap or brilliant?
OK. I would like to know what is the best fuel, specifically for BA XR6 and Ts. Been hearing a lot of bad stuff about Optimax and good stuff generally about Synergy and Ultimate... I use Ultimate (yes, it is tuned for it) on recommendation by the guys who work on my car. I know there's other threads on this issue, but I want to know - is Optimax really Opticrap or are there other issues? And could someone please enlighten me as to what the mimumum rons are for these fuels?
