US don't use RON do they? I thought around 93 US octane was about equivalent to 99. No idea how easy it is to get fuel that decent there though.I'm half way through, but looks like it's dropped either a rod or piston. I'm thinking he's just had it "tuned" in the UK, probably on 98RON, then filled it with pissy 87RON over there and spanked it on a drag strip.
