Oil filter was a Fram Ultra Synthetic.
The ending viscosity of this sample is 7.89. The minimum for 20 grade is 6.9, so this oil looks to me like it's right below the midpoint of the 20 grade range of 6.9-9.29. And it looks like every other sample on this sheet has stayed in grade (barely).I'd also bump up to 30. It's at the minimum

and others that commented on the silicon.Check your airbox to see if the silicon is from dust. I've had sealing issues with an aftermarket filter on my Subaru. It's also easy to miss one of the lower hooks when closing it back up.
I probably posted it with my older uoa posts, but I’m guessing the good filter was the Fram Ultra Synthetic and the bad filter was a Wix. I can’t remember off the top of my head if I used anything else on this car.I'm curious what oil filters you used for the two UOAs that included a particle count. One of them is exceptionally good. The other is pretty bad.
