Thanks, I'll look into it. It's a bit thicker, which isn't optimal for this engine's tight bearing clearances, but I'll have a look at it.

Trav had great insight on engine wear and I am of the opinion that it is possible that the previous owner didn't get the car up to temp before ripping on it or used an oil not up to the task. Again, use the Redline and uoa it, then use it again and get a more consistent answer. Good luck
You're probably right, I kind of freaked out when I saw the original numbers and grabbed the best I could find at Walmart. I have an oil change planned in the next couple weeks. These engines are a little hard to fill properly and check the oil level. I'm thinking to drain and turn the engine over to get as much of the existing oil out as possible.

OP should maintain current PP in the upcoming oil change to establish declining wear trends to be followed by a Redline 10W30 UOA to 'demonstrate' its socalled cleaning capabilities if and when iron and copper rises then .
I'm not going to reuse the PP after viewing the decrease in viscosity (see report above), especially as I plan to do a few more HPDE days this summer. The person at blackstone said viscosity is lower than it should be, which hurts my confidence in PP with this engine and how it handles heat.

Is there any documentation to show that being the case with Red Line oil?
I think the "dissolve" refers to cleaning up engine wear/varnish/oxidization. I don't recall the exact term for what it cleans, but the guy I spoke with at redline said it cleans aggressively compared to other oils, as you can see it has a 3x higher value of calcium than PP. Logically, it's very possible there was some wear or an additive used (who knows why), and Redline is aggressively cleaning it out.
