Colyn,
Keep in mind that there is about 400
million hours of aircraft piston engine experience in engines for which there
was no oil filter and they never changed the oil - - they just added oil as
needed. Engines had excellent TBO’s. In many cases, over 3000 hours.

Subject: [LML] 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.
