Buying Diesel in Abu Dhabi

[JonnyW]

I did a search and couldn't find anything on this so my apologies if it has already been covered. I drove to Abu Dhabi yesterday and on the way back tried to fill up in an Adnoc station and was told I couldn't as I didn't have a special card (eventually the supervisor let me have 100 dhs worth and I was fine). There must be lots of Dubai based landrover owners who drive to AD, do you have this card, is it possible even to get one or do you just chance it and have a chat with the supervisor?

Thanks,

JW
