Out of curiosity, last night I put a string around the magnetic plug and lowered it into my oil sample, wondering if there may be suspended metals in the sample. After 30 min. when I pulled out the magnetic plug it was clean. So those extra fine paste like fillings on my drain plug in earlier pic are not small enough to be in suspension.
