I had emailed Purolator about the new Pure One filters and they told me they were exactly the same as the old ones, only difference was paint color and texture. I believe there are cut open Pure One filters in other threads, they should be the same.
That's funny, busa posted on the thread with the new gold Pure One cut open. I believe he was engrossed with GA having one of their tete a tete's regarding oil filter function.
And yes, it really seems that Purolator is cutting corners compared to the blue PO, on the new and improved (efficiency) gold Pure One.
ODD. With their old blue can and packaging, they claimed 98% efficiency. Now, with the new coated cans and packaging, they claim 99.9% efficiency. In their email back to me about it, they said they had indeed changed the media to be more efficient. I wonder why we got different anwsers?
Btw, Purolator is offering some pretty decent mail in rebates on their oil and air filters; the coupon is on their website to download. Of course, it will take about two months to get your rebate check....
