Did the third drain of R&P on my 2013 BMW X5. There is a noticeable amount of carbon in the filter. There was also slivers of non-ferrous metal that I don’t recall seeing before. I should send off a sample to Blackstone for analysis. Hopefully everything is okay.
My oil consumption went from needing to add a quart after 4000 miles to not needing to add anything during the entire 5000 mile interval. So, it’s definitely doing something.
On to the fourth run. I’m supposed to have a spotless engine now, right?
