Atm moment my S3 is completly standard and I live near Sainsburys, the super unleaded they sell is only 2p more a litre, so I may as well use this even though the car is std? Esp when I get it mapped they will map to the constraints of the fuel, I can't face Optimax after 3 Subarus I spent a bomb on it. Either way the 97 Ron has to be better than the 95 Ron, I heard this fuel is Bp Ultimnate without the additives? Has anyone a chipped car that is running S-burys super? Any probs? Remap time is in June /ubbthreads/images/graemlins/smile.gif Opinions~?
