Hi everyone - I happened across a curious PDF file on the internets this evening - which should put to rest any speculation on what oils are approved for which specification.

The document I found is an Audi TSB dated July 2005. The subject matter? It's essentially a long list detailing which commercial oil brands, product line, and weight conform to the VW 502.00 standard - which is the successor standard to the 501.01 oil specification that our RS6 engines require...

I figured this might be a useful bit of information!
