It's got 97RON Sainsbury's fuel in it at the moment, the dealer filled it up for me. Manual says 98 is normal, Shell 99 is recommended but 95 is the bare minimum. Not sure how much of a difference stepping up to 98RON will make or even 99. I imagine this will open a rabbit hole of opinions on the best fuel to use in the M cars.

97-99 is all fine in my view and experience - I use either BP (so 97, as it is the one I pass all the time) or Tesco Momentum (99) or Sainsburys (97). I favour Tesco in terms of value and being 99. I think you'd only notice the difference between any of those in tenths of a second on a track...
I could never bring myself to pay Shell prices - just seems like setting fire to pound notes with no benefit... I know many M drivers will swear anything but Shell will halve your performance and melt your engine
