 Uh, no. Okay. You know, coolant would change it a different color, but I just want to point out that that engine does have some issues with the intake manifold gasket, allowing coolant cross-contamination into the engine oil, but it won't make it black like that. All right? I know. All right. You know, black like that usually is a sign of a rich running engine or a gasoline-contaminated oil as a byproduct. So that's why I'm thinking more towards fuel.
