Really when you think about it the filters job it to filter particles which on today's low drag, low scuff designs (all roller, no flat tapet etc) so not a lot of debris and it is the additives in oil that really break down so as long as the additives hold up (which are tons better today than ever before but you pay a premium for them) then the risk of premature wear is pretty low.

I'm curious to see my results, guess will find out.
