So run 1000 miles with the Rotella, carefully remove all the filings from your magnet and filter, then do another 1000 miles with another oil. Weigh the filings to 0.1g accuracy and that should give you a decent A/B comparison.
Good suggestion, however, aluminum is non-magnetic.
I suggest that we take stock filters only, add the OF super mag mod, soak the filter in oil for 24 hrs. then drain on its side for 24 hrs. Then weight. Put in bike, run for 1000 miles, remove, drain like before and weight.
Not totally 100% as captured dirt will weigh in. But better than trying to pick aluminum dust out of the filter.
BTW, I didn't know Rotella made klotz and mobil1
