If VW NA is issuing a recall, these failures might be from something other than the oil used. If VW suspected out of spec oil was used, and it was the cause of cats failing, my belief is they would just void the warranty.

Separately, VW NA just issued a recall on various VWs including the ATLAS due to premature wear on Catalytic converter failing. The 504.00 oil on mine is at 9.5k on 87pump on my OCI and still golden brown and The taillpipes have no soot. It's remarkable how clean these run on the right oil. The 508.00 0w-20 are the only ones that are green. It's a dye placed in the oil to indicate green.

In the meantime, I have bought 6 quarts of VW 508/509 oil, plus an extractor, so I CAN swap it out-- if needed. I really don't know whether to or not,, what do y'all think? I really wonder about NOT using the 508 oil, what might happen to the motor? Will the motor blow up? Got any thoughts on this?
