For my 2nd stage oil I added castrol GTX 10w40 with Delco EOS (6-8 cylinder) additive. I drove 765 miles minimum drive 25km (16 M), mainly highway but some city, varied rev's and gears, tried to keep rev's above 3200 and below 4200rpm but 5000 rpm did get in there a few times.

I found a local lab to test the oil so this week I'll take in my first and second samples to be tested. Below is what this oil samples looked like. What are the small yellow flakes? Is that possible paint from the new chains? There were about 6-8 very small metal flakes in the filter but I had to work to find them.
Any advice?
