Looks good.
This dino HDEO sheared more than I would have thought although that's not a problem since a light 30wt oil is specified.
Try a 5W-30 next time.

how do you know its shearing? he used an oil additive.

LC20 dose as spec'd would have been ~ 4oz at initial fill, plus an oz every 1k miles
Perhaps 7% of the sump, is what I estimate? Looks as though LC20's visc is similar to a "20 wt oil". The Civic Si is a high revving little engine, perhaps that also contributes.
Either way, wear is low, no contaminants. No issues.

Oopss... You got me
I've been driving it conservatively because I'm trying to maximize the FE. I've been keeping it under 4K RPM or less.

I can't see adding just 4 oz of LC20 lowering the oil's viscosity much.

I don't know what's in LC20. OP what oil was run prior to this?
