I had a UOA done with this oil from my '05 WRX, and had high levels of Silicone, Sodium and Tin. Well I still can't explain the Tin, but it seems Silicone and Sodium are at least present here in the VOA. My air filter is only about 5k miles old so that doesn't explain the higher silicone. I dunno about the sodium either.
Anyway here is the report. And I posted a link below it to the original UOA.
