I was not there at the time of the
oil change. I think I was wrong and it was on the drain plug magnet.
The mechanic told me that when he changed the
oil he found this on the magnet of the filter. But my filter does not have a magnet. I opened one 3-4 days ago and there is nothing magnetic there. So I guess my initial post was wrong and that these tiny pieces (most probably from the
oil lifter) where on the drain plug magnet and not the filter itself.
