Oil analisys is better than nothing, but it doesnt tell where the metal came from. It can tell you if it is Bearing material, aluminum, gasket, sealer, or iron/steel.
Yours sticks to the magnet. It is either iron or steel, period. That means that SOME of it stuck to the magnet. Some is in the oil filter, look in there. Buy a filter cutter, they are cheap, then look!
Keep in mind, anything you find in the filter went thru the oil pump. The gears are iron and are not likely much harder than what you found. BUT! The front cover and the oil pump housing is aluminum. Much softer! Keep an eye on the oil pressure after the oil change.
Always use the same weight oil and brand, that way it is easier to spot any pressure fluctuations after oil changes.
If you are not as anal as I am, you won't worry as much, but should you?
In my world, anal is short for analyze,
I don't consider it an insult.
Just sayin'
