Called the showroom just now and asked them to pay attendance to this thread and our fuel related concerns.
He clearly read out the notification sent by Atlas Honda and insisted that there was only a mention of "recommended fuel", no mention of it being "mandatory".
He further stated that their would be no logic in releasing a model for which fuel would not be available.
The status as of now is 3-4 months wait for the 1.5T.
I received my booking number as well.
Am I wiser now than before the call? Not quite sure, apart from the recommended/mandatory difference, whatever it means.
