Running 99RON fuel

[Kinky]

I've been looking at the Shell V-Power ads, and it got me wondering if my 5 could run 99RON fuel without any retardation.

Anyone running theirs? Any advice? Or is it simply a case of filling up and off you go.

H - I guess any 99RON fuel ... is there a difference between the tesco/Shell/etc/etc fuels?

That's the key I was looking for.

I wanted to know if the 5 would ok on a higher octane fuel, or if I might have needed to do something to get it to run as efficiently as possible. I run it on standard unleaded now, as I guess the owner before me did too.

AHA - ok - so the timing does need retarding.

Thanks for that
