FWIW I was trying to get the micron rating from Purolator on the new Gold 20000 oil filter that is now being sold at Walmart.
They did not provide that data. On youtube there's a few videos produced by Purolator and others who attended the official
roll-out of the new 20000 filter line, but nowhere in those videos of the Purolator marketing "conference" does anyone state or list the micron rating of that Gold 20000 filter.
I may be repeating myself but I also asked Purolator what the current micron rating of the BOSS filters was, specifically the PBL30001, and if that had changed since it was first introduced (25 to 46 or ??back to 25). They would not/did not answer that question.
Part of the reason for asking was to see if the BOSS filter had changed over time (ie: before and after MH bought the company), but also because most BOSS filters were updated (at least on the box) from 15,000 miles to 20,000 miles lifespan.
So was that just a marketing gimmick ie: no actual change to the BOSS filter itself or??
Also, FWIW, the PBL30001 still says "15,000" miles on the actual box (if you see any marketing images it may say 20,000 miles, but that specific filter still is rated for 15,000 miles), but again, no micron rating is revealed.
Point is, I've tried to get clarification from Purolator multiple times and their response was only "It's on the website", and I replied that the specific information is not on the website, and they replied "check the website", and so I double/triple/quadruple checked, etc,etc and then they stopped responding, never answered any questions about micron ratings. Seemed to me either the person that was responding was either lazy, didn't care, or was being evasive on purpose to avoid answering the question. IDK which.
