Blackstone commented that my aluminum, chrome, and iron are higher than they like to see.
Aluminum was 55, average is 53 and it was 49 previous
Chromium was 9, avg is 8 and was 9 previous
iron was 73, avg is 74 and was 63 previous

So it looks like I'm hurting stuff unless this is part of the damage from a couple starts over the winter with cold oil. My sample from the first 31 runs in 2018 is at the lab and I'm desperately waiting for results. Compression on the 6 cylinders I could get a gauge in were all 188 to 194. I didn't do a leak down.

One bothersome thing is that the oil doesn't test well for viscosity at 210F. I'm beginning to not like Brad Penn 10-30.
SUS viscosity at 210 is 55.4, should be 58-65 and was 55.4 previously.
