All mileage is in kilometers not miles.

Notes from oil slip: "Fluid apparently looked bad. Was it? We couldn't fill entire sample container, so do what you can with it."

Previous fill was Red Line 75W90. I'm not sure why the Aluminum has been elevated, so I'm going to try Red Line 75W110. Though I don't expect much of a change.

I'm not sure what the Aluminum wear is from. Anyone have any idea about the C7's eLSD diff?

The aluminum could be the new diff cooler as it's breaking in? I had it put in April 2019 when we also upgraded various cooling systems on the car. Maybe...
