Here's the latest UOA for the car, looks good I think. This was with a Mobil 1 M209 filter. I usually use a Wix or Napa Gold filter but wally world had these on sale for $5 ea. so I bought several. This is the first time I've used Valvoline Synpower in this car, it's been Mobil 1 since the first oil change and a couple of times with PP. Also This is the first time using 5W30, it's been 10W30 till now.
