LoL, yeah I wonder why. I called them not too long ago and asked, and they told me that info was "propriatary". Since when is a filter's efficiency a secret to the consumers?
It is proprietary when your competition boldly advertises efficiency spec's that you can't match ... when your competition says 99 % , it would be silly to openly advertise anything less.
Fram Ultra :
2-ply synthetic, metal-screen-reinforced media provides 99%+ filtration efficiency.*
*FRAM Group testing of average filter efficiency of PH8A, 3387A and 4967 or equivalent FRAM TG or EG models under ISO 4548-12 for particles greater than 20 microns.
I don't think "cant" has anything to do with it. Not like they don't have the resources, haven't had time to catch up or they are making something complex and hard to figure out. IF they wanted Fram Ultra or Royal Purple numbers they could have it to you within a few months. They have addressed this and simply believe there is a compromise between efficiency and ability to reach high capacity without jeopardizing getting clogged (going into bypass with real extended intervals. Now we all know there are many synthetic media filters that claim to go 15-25k miles with 99% efficiency at 20 microns with no chance of malfunctioning BUT Wix (when Wix was actually Wix) had no reason or history of compromising quality(not to mention the regular Wix has normal efficiency numbers) so its hard to believe they just arbitrarily have inferior efficiency numbers to even its own lessor cheaper filter with no real basis. Its basically a reliability feature for extended use and most people should be using a regular wix. I got that info from the horses mouth but that was back when Wix was Wix. I just don't buy the filter lol. I will use a regular Wix if the price is right. If I'm trying to do extended intervals on a fleet diesel work truck accumulating 60k miles a year or a tractor I might reconsider.
