Well the plot thickens. I just spoke to Martin at Premium Guard and he stated it's 99%@20 Microns for their synthetic oil filters and that they'll get the website updated. What to believeThanks for the clarification. I thought I had read that somewhere but I get Premium Guard and Pentius mixed up they look so much alike. Pentius does claim 99% at 20 for their extended filter, but I'm somewhat skeptical of that claim. The filter itself is a dead ringer for a Premium Guard (cloned?) and it also appears to by a syn blend media at best...I'd expect more in the 95% at 20 for that type of media.
I don't think pentius shares any filters with PG w/ pentius making a good chunk of their filters in South Korea.
Pentius sent me this pic for their synthetic oil filter line a while back.
