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.

  • See this, it is their own certification standard so it will not translate directly to API.....oilspecifications.org/articles/… – Moab Jun 25 '18 at 13:07
  • This lack of VW certs does not mean there are not better oils out there. – Moab Jun 25 '18 at 13:07
  • It really annoys me when manufacturers do this - it's just to try and force you to buy their own consumables instead of generic ones. I had the same thing with coolant in my Subaru... – Nick C Jun 25 '18 at 13:13
  • BobIsTheOilGuy website claims: VW 502.00 Oil for high performance gasoline engines without extended oil fill change interval (15000 km – 1 year), HTHS viscosity min. 3.5 mPa-s, ACEA A3 + additional VW tests ... not sure if that helps. I agree with @NickC here ... PITB. – Pᴀᴜʟsᴛᴇʀ2 Jun 25 '18 at 21:14
