Purolator Classic Efficiency

[The Critic]

I picked up a Purolator L14610 at WM tonight. The box stated 97.5% efficiency at 40 microns.

Wix Premium and Fram TG cite 95%+ at 20 microns.

Does anyone have the Purolator Classic's efficiency at 20 microns?

Even though I'm using this for a 5k interval, the efficiency does seem pretty low...and I'm sure the capacity isn't great either.

Did you check the other larger PC filters? They probably state 97.5% at 20 microns. As with the smallest PureONE filters, the Classic ones seem to be rated at 40 microns instead of the 20 microns the rest of the filters are rated at.

I suppose I could, but it really isn't helpful for me and my purposes.

This was all about the Pure One's beta effiency, and how it thrumps everything else out there. It went on for quite a while with a number of people refusing to believe what a Purolator's engineer put into writing, with his name, and made public.

Again, Japanese auto makers have long specified lower efficiencies in exchange for higher capacity media. I think four of the smaller filter sizes are rated at 40 microns instead of at 20 microns. It is no coincidence that these smaller filter sizes are also predominantly Japanese/Asian applications. Purolator does not simply use the same media and cut it to fit different filter sizes; the media can be specific to the filter application.

Keep your oil fresh and you have no need to worry about efficiency ratings.

I called Purolator's Tech Dept. several years ago when I discovered BITOG(2004-05). And the engineer on the phone told me that the Puro Prem Plus(a.k.a. CLASSIC) and the PuroOne both trapped between 10-20 microns and the P1 just trapped a higher % of those particulates. Now they're saying that they trap 20-40 microns?

The Puro website boasts "97.5 percent" efficiency at 20 microns, but then double asterisks to "when applicable". Apparently that's the exception to the certain filters already mentioned for Japanese apps.

The double astrix note on Purolator's website is actually pertaining the the ADBV. The only place you will see the 20 vs 40 micron difference called out is on the actual filter box.

Why do they even bother putting that on the box? Why not just put "100% efficiency at filtering small bowling balls" ?

i only use group 7 which are purolators or the classic i like my oil to flow
