I did a little research on oil filters = and=20 discovered that:

a) champion bypass = pressure=20 differential is below continental spec

b) champion particle = size is 40=20 microns which is right at expected film thickness. auto spec is = 25=20 microns

c) in general, much = higher=20 efficiency filters are available to the auto-industry

I'm wondering if anyone on the list has = experience=20 with better filters.

thanks,

Colyn
