turbulent kasi sa loob ng oil filter( madalas may pressure differential) there is a good chance yung naipon na dumi might get dislodge simultaneously during the high revs pag mataas oil pressure tapos bigla bumaba pressure...

sa drain plug which is the lowest portion doon sa engine, especially dahil metal fragments sila, im thinking na doon mag settle...
plus hindi masayado turbulent doon dahil malayo sa pressure differential...

im thinking na yung drain plug doon kakapait yung mga pwede ma-magnet na particles, safely

yun ang rationale ko, although wala tayo definitive proof if even placing magnets does help... kakatuwa lang ilagay, parang it just makes sense hahahahaha...
