Was browsing around Donaldson's website and noticed they appear to sell a filter for applications requiring either the FL500S or the FL2127, the P577066. Has anyone had any experience with these, or with Donaldson oil filters in general?

They don't give a 99% or 99.9% micron rating but they do claim 50% at 6 microns. Does anyone know how that stacks up against the PGI 99% at 20 micron filters?

Filters that are 99% @ 20u will typically be around 70-80% @ 5-6u.
