Do any of you people who have had your Countachs or a while use octane booster in the fuel and if not in the UK how do they get on in France. I've also got one rear Pirelli with not much mileage on it if that helps anyone out?
I used to use Millers VSP as no one could give me a definitive answer as to whether the CT would run happily on unleaded. I think that used to bump the octane rating a couple of points as well.
