Ok - I was going to wait 50 miles but just could not wait. I strapped rare earth magnets around the outside of the plastic oil filter housing and they did catch some ferrous material. There were 2 pieces of metal I would consider "chips" though quite small, and there was also what looked like aluminum dust, and some small pieces of sealant. I'm up in the air if I change the oil, or run another 50 miles then change the oil. The majority of what was caught I would categorize as ferrous dust. Perhaps finer than the filter could catch. The magnets are about 1 cm in diameter.
