After all the hype, I was finally forced to try this yesterday.

Contrary to other opinions I've read on here, I saw less knocklink activity and a noticeably faster pickup through the rev range, particularly under heavy load in 4th and 5th on the mway.

 

I've tried BP Ultimate, Optimax and Super Unleaded from various places and I can honestly say that I cant tell any difference between the lot

To be honest I can tell more of a difference between a day that is circa 0C and 10C than between Optimax and Ultimate, apart from the size of the hole in my wallet of course

 

i have just ran a tanks of Ultimate & optimax on my RS & can honestly that i am converted as of now to optimax WOW !!
