These pics are under the valve cover of my Toyota 7AFE engine from my 95 Geo Prizm at 153296 miles that I took yesterday. No Auto-RX, Mobil 1 was in here since 139,960 miles, synthetic since 136k according to the previous owner. My most recent oil change, I decided to see what Delo 15w-40 would do with my UOA's. I've been using LC as well since I acquired the car. 500 miles into the current interval so the oil is coating the engine to make a brownish tint to everything, as you can see on the valve cover a gentle wipe with a shop towel and things are clean and silver-shiny for that center hourglass shaped part of the cover. I meant to do this when I got it but I hadn't got around to it until now.
