99+ octane unleaded not that popular nowadays or is it??

I use V power in mine only, Tesco super if I’m in a pinch

On my 2017 c63, it states 98 or higher, sometimes I use BP super which is 97. Does it really matter that it’s only 97 ? What’s people’s thoughts?

You’ll barely notice the difference, especially now the colder weather is coming in as you won’t get the chance to explore the fuel limits. Won’t do any harm either. I’m lucky to have a few Shells around with 99 Ron but my nearest station en route to work is BP with 97 and I do occasionally pop a bit in
