I am trying to figure out what certification VW's Certs translate into as API, if that's even possible?
Looking for oil for a '08 2.0T Passat, and it looks like it's calling for VW 502 cert.
Some oils clearly say VW 502 right on them... That's great... But almost all oils will list a API cert.
Looking on the boards finds "tons" of people "running" T6 in their gas engines. Subaru-world tends to love it, too, as well as many cycle communities.
Can someone explain why or why not T6 isn't ok?
Thank you for your time.
