Tacking on my oil analysis to this thread. Low miles on this sample (600-ish), but I wanted a gut check on how things were fairing internally. There's about 2000 miles on the build in total. All looks good according to Blackstone.
I've been running 15-50 Driven HR1. When I took this sample I switched to 15-40 GP1 to lower the pressure a little bit.
