 Right? If you heat the oil for 30 seconds, do you get sparkles out of the oil? Does it flash and pop? I don't think you will. We're talking about, at this point, the fact that the engine still runs, but you're getting noises. We're looking for bearing wear. We're looking for small metal particles the naked eye can't see. All right? Because if the naked eye can see them, that means you've got a much bigger problem and you're so far down the road, then it's time to do an engine repair.
