I do not know if this is design dependant, but most german/british car owners will crap their pants at the sight of metal shavings, especially the highly tuned engines with super tight tolerances - example - if you had an E92 generation M3 and saw metal shavings in the oil filter, standard recommendation is to stop driving and take it to the shop (preferably a well versed indy instead of the dealer). but then that generation is known to have rod bearing issues. so it becomes an instant freak out factor.
The only toyota I have had till now was a scion XA in grad school. that and none of the other cars I have ever owned have ever had visible metal shavings in their filters. I will typically tear open a filter after an oil change to look for this. Good to know that the LC filter makes it easy.
Asking the general community here - do you guys/girls typically run oil analysis on the oil coming out??
