Had my oil changed today and asked the dealer to fill a sample bottle for analysis. The service manager tells me that he thinks they will come back and say there is too much metal in the oil and that they always do for Porsche's.

Has anybody here had this done and what was your experience with Blackstone?

 

I can't comment on Porsche, but I've used them and find their service excellent.

What they will do is let you know how the oil compares to other engines of the same model. Also, if the metal level is high, what is the Porsche oil capacity? One would think the dissipation would be greater?
