Ok, so I did oil change today. Mileage was 5278, first ARX clean stage, with double dose.
Oil came out very dark,black. Similar to used oil from diesel engines. Arx is black and Moly additive is black/grey. No chunks or very thick oil. I would say looks normal. Before drain, I sprayed almost full can of Amsoil Powerfoam, into intake thru breather hole, while running engine. Bunch of smoke as after/during seafoam. Let it sit for about 10-15 min, meanwhile cleaned Maf with maf cleaner. Put all together, throttle body looks nice and clean. Ran to store to get some beer, and to get [censored] out after powerfoam.Car was running at little higher idle.
After oil change, I checked under PVC valve, looks clean enough, just little varnish, no sludge looking stuff.Valve was wet and oily so, I guess it works. Also night before I put in Lubro Moly valve cleaner right before fill up.
Now pics:
Oil that went in for rinse phase.
It is API SJ and SH, what I heard why those oils not certified higher, only because new oils should be looking gold/clear.
That's how that oils looks:
This oil is blend with lots of Moly in it.I hope I will bring full syntech version that looks toxic green, next spring from Europe, and than go to oil change place and see their reaction

P.S. Filter on is OCD, should be fine for 1000 mile run.
