OK, I have an Audi S4 B6 which requires a VW 502.00 oil.
I see from various oil manufacturer products information, that the later VW 504.00/507.00 spec oils are backward compatible with earlier specs such as 502.00 (with some rare exceptions on the diesel side, where the 507 spec does not replace 506.01 etc).
Can anyone definitively tell me if the VW spec test for spec 504.00 includes all the requirements of their earlier 502.00 spec test?
I've been told that while 504 CAN be used in place of 502 on my Audi, the 502 is a BETTER oil in terms of wear and protection.
All of this is in the context of regular, fixed duration oil changes, NOT for use in extended oil changes.
Can anyone confirm or deny this opinion?
