I log almost every pull I do. Nothing stands out, no extra timing pull on C4, and avg_ing stays below 1 all the time.

I did C2,4 and 6 compression test 3 times each. I also cleaned the seat a bit to see if there was a leak, but results were within 15psi. C4 did drop to 165 as the very last measure, but that could have been from the oil cooling.

I'll take a closer look at the old plugs. Nothing stood out, but I'll get a better pic of the electrode.

One thought I had was a bad injector. I swear I got a low oil light very soon after installing the PS2 and have wondered if it has a bad seal. The oil consumption could be unrelated to the plug deposits and dark piston and just be coincidental.

Edit: coils and plugs were replaced 12k miles ago. Then replaced the plugs again now.
