Please note this is NOT a "slam AMSOIL" post.
It took a couple of attempts, but I finally got an answer from AMSOIL to the following question:
Hello - This is the second time I have written about this issue. I wrote a little over a week ago with no response. I am a preferred customer and recently ordered a case of the 5w-40 Euro oil for my 2005 VW Gti 1.8t. I thought the oil was VW 502 approved but on the bottles it says "recommended" but not approved. I would certainly appreciate knowing if it is approved or recommended and what is your stance on VW warranty requirements and the 502 spec. Please contact me. Regards, "JKH"
Here is their response:
Thank you for contacting AMSOIL with your concerns.
In response to your inquiry, Volkswagen (and most other manufacturers) does not make a list of "Approved" motor oils. They simply list recommendations.
Thank you again for the opportunity to respond to your concerns. As always, please feel free to contact us again if we can be of further assistance.
Sincerely,

Now this is not the answer I really wanted, but was masterful if you look at what was not said. They took NO position themselves but rather deflected to the auto manufacturer.
I wish I could get something definitive, but it looks like I am stuck, at the moment, using BC 5w-40 ... when I would really like to use AMSOIL 5w-40.
Interesting response.
