what's the highest octane you've put in your cayenne?
 

Has anyone put race fuel in their GTS/Turbo or whichever model? I am wanting a higher octane for performance trial.

I was wondering if anyone had a dyno performed with the different octane ratings...

Thanks.

100 octane, doesn't feel so different...

98+ in all my cars, but don't own a Cayenne yet. I have seen many people fill up Cayenne Turbo/S with 98 here.

I heard some guys mad a mix of 105 but only turbos with work would see any difference

I use 98 or 100 octane depending on the station I fill from. I "only" have the V6 but don't feel any difference between 98 et 100!

98 octane unleaded

wonder if race fuel would help?.....

I have a techart TT and techart says 100 octane only... been using Vpower.

the only way you'd see a difference is if you tune your ECU for the new octane
