iv been using normal diesel.. its either IOC or Reliance
no problems so far
As far as I am concerned, id not be buying the box until my car completes 10-12k atleast. after that id be convincing my father for the same for the next few months
BTW I would love to know the performance stats(0-60, 100, 160 timings) before actually plunging to buy one.
cheers
