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. This is not a probability of success.

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.

6 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Blackstone Oil Analysis report: I don’t know how to interpret these results. Is anyone experienced in reviewing these? It looks good to me, but I don’t know if there is anything that I should be concerned about. Is this report average, good, great, excellent etc. Oil report

POST 2Original post

That's an OK report. It's just ONE report, so we don't know much. For example, are wear metals (Iron, copper, Alum, lead) going up or down? Keep doing the tests. And update in 2019. Why are you using a 10W40? You don't want to use a 10 weight oil. You should use a 0 or 5 weight. So, 0W40, 5W40, or 5W50. See how low you are in the spec range for viscosity? That's classic Mobil One shearing down. I suggest using Mobil's 5W50, and it will greatly improve, and is still A40 Porshe approved. Your wear metals should follow, with a slight improvement in 1 or 2 changes, and drop 1 or 2 PPM.

POST 3 / ORIGINAL POSTEROriginal post

Oil weight was a typo. It’s 0W40. So do the trends is what is more important than comparison to similar vehicles?

POST 4Original post

See this thread..... https://rennlist.com/forums/996-foru...-analysis.html There are a bunch a posts around 100 that have postings of the findings.....I am one of the last posts with four oil analyses, #199. Scroll up from there, but you can get lost with info in this thread. https://rennlist.com/forums/showpost...&postcount=199

POST 5Original post

You also need to compare to equivalent oil. My Driven 40 would not be a good comparison.

POST 6Original post

That makes sense now. That is very classic Mobil 0W40 shearing. Stop using it. Start using a quality A40 approved 5W40. Unless you drive in the winter, use a 0W40. Then change for spring-fall. Mobil 5W50 would be a great choice.
