Super unleaded worthwhile in c200k?

[cookci]

Would i be wasting money by running on super?

I ran the tesco 99RON stuff through my c230k for 6 months and the difference was not noticable.

I use tesco 97ron as theres no 99ron at any of the tescos near me. It states in the book that the C230 should be run on super. What does yours say about the 200? I wouldn't bother unless it tells you too.

c36 defo runs better and actually gives better fuel economy on super!

I used to use unleaded and get about 270-300 on full tank... now i full up with super and i get 320-340 all the time... it does give u more miles, less knocking and smoother power delivery.

Does your engine suffer with knock (pinking) when using regular unleaded then? If you're still getting some with super unleaded too then it would be worth getting it checked out.

I use normal unleaded in both mine, unless I'm going to a gtg or a track day, then I treat the old girls.
