Before I get slaughtered on here, I'm new to the site and new to S3's after only buying mine last Friday. Also apologies if this is covered elsewhere, I couldnt find any threads on this.
Wanted your opinion - when driving my car back to Glasgow area from Aberdeen last week (and almost losing my liscence in my first outing), I put 'Normal' 95 petrol in the car. Got home and put some more in. On the way down, the car seemed very quick (not sure if its remapped) and more recently, it seems quick, but not AS quick. Last night, went down to my local BP and put BP Ultimate in and straight away, the car seems to run better but i haven't given it the beans as yet.
However, my question is, whats better and why? BP Ultimate or Shell V Power?
