Colyn,
 
I installed the ADC oil screen and have been very pleased with it.  (See http://www.aircraftspruce.com/catalog/eppages/adcsystem.php ).  100% of the trapped particles are right there on the surface and could be seen at a glance.   It traps particles far finer than a paper filter.  By-pass triggers an indicator lamp and there is provision for a chip detector as well.  And cleaning is a snap.

Subject: oil filters - 21st century preferred

 
I did a little research on oil filters and discovered that:
    a) champion bypass pressure differential is below continental spec
    b) champion particle size is 40 microns which is right at expected film thickness.   auto spec is 25 microns
    c) in general, much higher efficiency filters are available to the auto-industry
 
I'm wondering if anyone on the list has experience with better filters.
 
thanks,
 
Colyn
