For servicing you must use 507.00 ( or 507.01) or 506.01 Castrol oil.

attached is VW reponse

response 1

Thank you for contacting us through the Volkswagen Australia Website, we appreciate it.

In response to your email enquiry, I can advise you that the correct engine oil for vehicle is Volkswagen 504.00/501.01. Any oil used in the engine therefore must meet with these specifications. Depending on the oil manufacturer as to which one of their oils meet this specification the oil may be either 0w-30 or 5w-30 and must be fully synthetic. The engine oil for use in this vehicle is the same or similar to that as used in some of our high performance petrol engines and as such Diesel engine oil may not be suitable. I would suggest contacting the individual engine oil manufacturers to ascertain which of their oils they recommend to use to meet this specification. Alternatively your dealership would be able to assist you further with the purchasing of engine oil.

reponse 2 after I mentioned that my Golf is diesel

The correct oil viscosity of the 2.0L Tdi golf is 5W30. Please note we supply this grade of oil purely for the convenience of the customer in the case that the VW oil is unable to be obtained. If you are replacing the oil then it must be replaced with the genuine oil only. If it is found that any component has failed due to the incorrect oil being used that part may not be covered under the vehicles warranty .

what I would like to know is where Mobil oil comes into it?
506.01 is 0w-30 SLX LongLife2 and you can buy it from the dealer. To me it doesn't matter how much it cost because if you don't use correct oil your engine valve train will eventualy fail, maybe it will be at 80,000km or sooner and than the difference betveen right and wrong oil will be payed many times over. There is a lot of writing at tdi.com forum about it. To me it is not worth the risk.
