I have read that filtering under 3 microns can strip VI improvers and antifoam additives from oil. Does anyone running Franz or Amsoil bypass systems test for viscosity at 100F and 210F or test for defoaming?

I've got a 2006 Chevy Colorado Crew Cab Z71 with the automatic transmission. I get about 20 mpg on my 10 mi commute and about 23-24 on longer highway trips. My wife gets about 15-16 when she drives it only in town. The I5 is actually a dang good motor. I've been really pleased with the truck.
