The zinc in your Subaru uoa is too high though. It exceeds Energy/Resource Conserving specs. Unless you put in a zinc additive, the zinc reading may be incorrect. Might want to ask Blackstone to retest. The first one is Subaru oil, correct? Also, calcium is too low and magnesium is way too high.

I have not included any additives in my oil at any time. The first UOA was actually with Castrol Edge. I had the first oil change done at the dealership and just figured it was with Subaru synth. My bad. The UOA should say Castrol though, I'm pretty sure I wrote that down on the slip.
