I don't know if the guy will post it here and no I'm not cherry picking, this is the first multiple runs uoa with an engine that is broken in that I have seen over on another website, yes hemi's are high wear engines get that out of the way first. 4 uoa's, last one 30 weight then 2 20 weight runs and first looks like another 30 weight, wear dropped like a hot rock. Additive packages look very similar, last run PUP.

22,634 10,184 9.79 A6 I-28 C-78
It looks like he went 30,20,20 and then 30 as far as weights. I chalk the high copper to a young engine in the first uoa, that oil was put in with only 12k miles on the truck. But looking at the numbers one could easily say the 30 weight is producing less wear. I don't know if the guy is a member here or wants me to post the uoa, but this is the meat of the uoa. Last run was PUP, likely all the runs are PUP, bt I don't know for sure other then very similar additive packages. The first uoa's iron was amazing as well as the last, both 20 weight runs not so much.
