i only run mine on V Power mate and i love it, i noticed a difference in performance and mpg over Optimax as soon as i tanked it.

It's supposed to be 99RON but that's only according to the guy in the Shell station i fill up at, doesn't actually say it on the pump

Any high grade Super unleaded should be ok, i'd avoid supermarket 97RON stuff as it's probably nowhere near as good as it should be.
