Oil changes with HPOS

What oil change intervals is everybody using that have the BO systems? Does the oil break down faster using the two pumps and running higher pressures?

I'm wondering if I can go with extended oil changes since I have an Oil Guard filtration system.

I run 4k on Delo 400 or Delo LE. Viscosity loss due to shearing is not considerably worse in my case than without the daul pumps. There is certainly an increase in shearing though. Oil samples are the only real method to determine what your OCI needs to be.
