So as per reply of BPCL to ported_head, they have quietly introduced 91 octance in metros. I remember reading a press report somewhere in April / May that the refineries were having problems supplying 91 octane to meet BSIII norms for metros. So in effect we are paying 2-3rs more for the additives, which may or may not be necessary. Maybe I should go back to IOC regular instead of xtrapremium and see whether the difference is noticeable or just a placebo effect.
@subbarp: if you filled at different pumps, the octane rating may have nothing to do with it, simply the quantity calibration - which we all know can be quite haywire at some pumps.
Which are the BSIII cities by the way? Other than 4 metros?
