I've never seen oil look so gross. Like dark Dutch processed cocoa with a bit foam. It looked almost as nasty as my rear differential fluid. I'm a bit surprised, because my engine looks, at least around the cams, pretty much spotless. I guess the M1 did some cleaning. The 5W-40 had 8k miles on it. A sample is going in for analysis.
