EA888 gen 3 - Swirls in Oil

[kosmaras]

This is a 1,000 mile drain on an 80k mile ea888 running an e50 blend. Oil looked totally normal upon initial drain, but after sitting and spinning it around you see some minor swirling only when shining a shop light into the drain pan. Can’t say I’ve ever moved the old oil around this much before to say I’ve seen it or not in the past. UOA’s usually good and no meaningful metal in filter. Engine sounds great.

Edit: oil used in engine is LiquiMoly Leichtlauf 5w40. Maybe it’s additives?

I’ll work on easing my paranoia going forward

It could be blow-by or other gunk that the oil picked up and dissolved. Unless you see forbidden glitter in your used oil, your engine is doing just fine.
