True but even the AAP filters made by purolator were 96% @ 20 microns according to the packaging, so I'd think the motorcraft was at least that good.
Hard to say ... I've tried contacting Ford and the Motorcraft parts division of Ford and can not get any oil filter efficiency data from them ... ZERO. Their canned answer is "contact the nearest Ford dealer" ... yeah, like the dealer is going to know what the beta ratio is on the Motorcraft oil filters. I doubt they even know what beta ratio means.
But yeah, if you want to
assume the Motorcraft filters made by Purolator use the same basic media as the Classic, then you could
assume they are also around 97~98% efficient.
Nothing about efficiency ratings:
