just circling back to this. with similar usage, the redline 30wt (thin 10w30) showed no copper wear, so they do something really well with film strength in that oil. I'll probably switch to that one full time, maybe with one quart of 40wt in it, and see how that goes.
high zinc, high moly, large amount of Group V base stock. It’s a great combo.

I would not mix viscosities. Either move up to a 10w40, or stick with 10w30.
Got my latest oil results back. I had a couple internal parts changed around this time, so I think it helps explain the outcome. It's my first time around on Lucas. I stepped up to 20-50 this time around since the tracks are going to open soon. We will see how the next one goes now that all the new break in metal is gone.
They said some of the moly came from the coating on gsc cams (first oil change since cam install). But ya, I have never seen zinc and phosphorus so high. Crazy stuff
