bobistheoilguy is an excellent resource. We may have limited choices, but both the Mobil 1 ESP and Castrol SLX 507 approved oils are excellent. Some of the other European 507 oils such as Motul 507 specific are also available here on the internet.
The Amsoil has not been certified by VW as an approved 507 oil. Amsoil says it meets the specs, but they have not put the oil up for testing and certification. I'd consider using it after the warranty period since they do have good products, but not before.
