Robin,
IMO your engine looks great. Your wear numbers are great and your engine is just fine. Whatever you are doing is working out well.
I only have one issue, and it does not in any way reflect the condition of your engine. Your engine looks great and the wear metal numbers reflect that.
This might be a little nit picky and technical but the numbers on your oil viscosity to not match up on your blackstone report. Blackstone is reporting a 73.3 SUS viscosity at 210*F and a 13.82 CST viscosity @ 100*C. Both of these test results are within a 40 weight oil specification, but do not equal each other on a comparative viscosity chart. Does it matter in your situation? No. I just noticed the discrepency on your report. A 13.82 should be under 70 on a comparative viscosity chart.
I'm sorry to be picky, just seemed to be an odd reading when they should be closer. But, the bottom line is - both results are within the 40 weight oil specifications and your engine wear numbers look great. Keep doing what you are doing because it is working for you.

Converts perfectly, 13.82 cSt = 73.306 SUS, unless this formula is wrong:

I was using a comparative viscosity chart similar to this:

Rich & Clux,
Thanks for the feed back and links. The SUS and cST is something that Blackstone does not elaborate on in the enclosure that comes with the report, or on their website. At least I couldn't find it. Now I know
