RE: K&N filter test -construction equipment

I feel I have to ask, just for the sake of thoroughness...  Was the K&N
properly oiled?

My first reaction is surprise, since I thought the oil would certainly
catch dust better than a dry paper element.  I've had a couple of K&N's
in different cars (not yet in my current 200qw) and just accepted them
as better, even if only marginally so.  What if you oiled it real good
and just didn't clean it?
