Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order.

I changed the oil last week and used Blackstone Labs for an oil analysis for the first time.

This can happen immediately after an oil change, just before an oil change, or it may not happen at all the whole time the oil is in service.

I view oil analysis like an annual physical exam's blood work up; i.e., look for changes over time.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I don't post a whole lot in this forum because my 996 runs so damn well. I don't have a lot to offer in fixing stuff because I haven't had much work to do! I changed the oil last week and used Blackstone Labs for an oil analysis for the first time. I thought I'd share the results:

POST 2Original post

Thanks for sharing an it looks quite healthy for 6k oil use. Don't quite understand why they said Aluminum doesn't track with mileage though. I thought all metals do since virgin oil should have 0 metal in it.

POST 3 / ORIGINAL POSTEROriginal post

Quotes source post: 10408731

Yeah... good point.

POST 4Original post

I use Signum Oil Analysis, a Mobil company, and their measurement criteria aligns nicely with Blackstone. FWIW, in re. my '99 w/68K miles and annual oil changes w/about 6K miles each, my AL ppm typically runs 3-4. Once I saw a 7 after about 10K miles. I view oil analysis like an annual physical exam's blood work up; i.e., look for changes over time. relinuca

POST 6Original post

Quotes source post: 10408731

The oil analysis does look pretty good. A very large percentage of the internal engine surfaces swept by the oil is aluminum. Any bit of alum. flashing that comes loose will invariably end up going through the oil pump and being pulverized. This can happen immediately after an oil change, just before an oil change, or it may not happen at all the whole time the oil is in service. There is also the chance a bit of alum. flashing trash in the oil sump gets ingested by the oil pump and this can cause a bump in the metal content of the oil, alum. in this case.

To add another report to the pile, here is my report from last week:
