BMW recommend 95RON fuel but all official BMW performance data comes from using 98RON. Been using 98RON for as long as Shell had it available. (Years ago it was called Optimax & currently V-Power) Extra kms driven compared to lower RON fuel.

Cleaner burning as far as manufacturers' claims go.

My dealer started me off with a tankful of 95RON in my F30. I then put 98RON after using the first tank. I could feel a distinct performance improvement from the 98RON. Will ALWAYS use 98RON in my F30.

98RON recommended.
