grrrrrrrrr

I wish, the highest RON we get ANYWHERE in N Ireland is 97

People have told me to use octane booster but I dont trust that stuff. Any of you have experience of it? I wouldnt even have a clue where to start. I have no intention of using it but I was just wondering what the story with it was. I just wish Tesco, Shell or anyone would bring there 98 or 99 RON over. The excuse apparently is that it costs too much to bring it over from the mainland england/scotland. Why then bring crappy 97? I notice no difference using it compared to 95RON in either my R32 or GTI.
I wanna book a week in England just to get a run on VPower to see what its like.
Santa please bring me some nice quality petrol
