I've used Shell for a quite a long period, now shifted to BP for last 2-3 months, due to non-availability of Shell in my nearby area.And to my surprise there was no mileage drop nor any difference in driving.So I could safely say that there is not much difference between un-adulterated fuel in any normal bunk and that of Shell,atleast the kind of difference I could notice.So in a sense I said bye bye to Shell already and with the price difference of 6 Rs it doesn't at all make any sense. |
