and after how many miles does this occur ?  If the oil still gets through, 
why bother changing the oil/filter at all - especially if nothing is broken !

So, why do a single thing to a car from new ?

wow,  it's a good thing you aren't involved in the aircraft industry !

on another note, orange filters have a drainback valve ?  90% of engine 
wear is on cold startup and if all/most oil has drained back from upper 
system (head, cooler, etc.) what might the situation be ? (at least for a 
short but critical time).

Uhmmmm .... no disrespect here but your consistent reasoning suggests you 
might be involved in academia ?

just curious,
