OVERKILL
$100 Site Donor 2021
I'll add that @wwillson you might recall I had a similar experience (but without the trend of UOA's) with my Expedition. It had spent its life on bulk dealer oil prior to our purchase of it and when I started running Mobil 1 in it, I was getting all this carbonaceous material in my filters as well. Took quite a while to taper off.
