RON fuel rating for Cayman

[PorscheJW2014]

Hi all,

Picking up my Cayman this week, and I have heard that it is meant to be run on 98 RON Super Unleaded. I wont be running any less, eg. standard 95, but does it hurt to run any higher? Like Tesco Momentum 99 or V Power Nitro? I don't mind if you gain nothing from it, I'm just worried about running the wrong fuels. I understand about running it below the recommended RON rating and it reduces the ignition timing to prevent knocking, but what happens when you run a higher rating? Around me they all have at least 99 or 100.

Sorry for the noob question. I know there are many fuel threads but all I could see was people discussing whether to run 95 or 98. I want to know if it hurts running a higher figure than 98.

Thanks a lot!

Thanks for all of the great replies everyone! All of the petrol stations around me are always busy, so no worry about fuel that's been left stagnant for days. Really interesting replies, I'm glad I asked the question! Thanks a lot!

I pick up the car on Thursday around 3.30pm. I will post pics on a new topic when I get a chance!
