on 504/507 oil?


I don't think most people are using 504/507 oil in gasoline VAG engines in the U.S.

Also, I'm not sure it would survive U.S. fuel for a 10K mile interval, though it seems to do OK on a 5K mile OCI if my recent UOA is any indication.

I noticed that the reasons they gave for adding the port injectors did not include "washing the oil vapor buildup off the intake valves, which has been a pervasive issue in DI engines that we have attempted to sweep under the rug."
