This UOA was performed at 7700 miles on the truck. Oil was in the engine from 4700 - 7600, roughly 2900 miles on the oil. Keep in mind some wear metals are still there because of the break-in. It takes a while to flush it all out. Many say upwards of 20k miles.
Iron is a little higher than I expected, but this is hard to tell if this has anything to do with wear vs normal break-in. Viscosity held up very well. Right on the edge of being a 30 grade after 3k miles. 0 fuel dilution and additive packs look really good at this mileage. The manganese is coming from a fuel additive most likely. Anyway, I wanted to share these results from my first UOA. I have an engineering background and I've built / balanced a few motors in my life. Always nice to see things wearing in properly and actual data.
I am OZ tuned and I consistently run E40 - E50 fuel. If anyone is interested in doing one of their own, these guys are really good. Lake Speed Jr is a legend in the industry.

Viscosity chart :
xw-20 = 6.9-9.2 cSt
xw-30 = 9.3-12.4 cSt
xw-40 = 12.5-16.2 cSt
xw-50 = 16.3-21.8 cSt
