oil change on my 360

What you see on my finger is the total amount gathered from the magnet not just a sample. I hope next oil change I will not see this again. I managed to get a magnetic drain plug and have left the magnet out of the filter. New filter and new 20w50 oil. We shall see. It is what it is.
