Agreed that Euro 95 RON is ok, but the link to the US explanation of their octane rating is just an odd way of doing things, I thought RON was universal so could be compared across countries, creating their own 'MON' and then creating a third octane rating by averaging the two achieves what??
RON is important but for me it's the potential cleaning packages that should make a difference long term so I do use super for daily stop-start journeys but often use 95 for longer motorway runs.
