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.
