What air and oil filters are you using? Hopefully the silicon is still from break-in because it typically drops a little more quickly.

I can try sending the next sample out to those guys and see. Not sure what's up with the oil weight. It should be the same formula as the 3rd report and about the same miles. The only difference is I took the sample cold this time.
I still have the original air filter in which is made by Toyota. I checked it a few times and knocked out a couple bugs but it's still white. It looks like an industrial HEPA filter compared to most stock ones! I'm using the Subaru stock oil filter which is the black wide one by Tokyo roki.
