| Apologies if i'm being obtuse, but could someone answer a question for me:
Normal supermarket petrol seems to be derided as cack for you enging, Optimax& Ultimate are better... but is it purely a numbers game? Petrol Top trumps?
I read about additives and stuff, isn't it just petrol?
I'm a bit of div on technical stuff so no science if at all possible.
