Purolator Efficiency on Upgraded Oil Filters

[bullwinkle]

I was under the impression the Boss series would do pretty well - I’ve always thought of it has as a Mann fleece filter, as found on many Mercedes in a can rated for 15K.

Now that Fram cheapened the Ultra series - is there no “real” depth media on the automotive side of things?

Still have Royal Purple & Amsoil; also, Fleetguard Stratapore & Donaldson Blue (if they make them in a size you can use). More $, unfortunately...

So what’s the efficiency of the standard red purolator?

Before or after the media splits

The same as any other filter that splits. Been checking my filters for over 12 years now. No filter on my vehicles has split in that time. It happens but how many million of filters a month don't?

When's the last time we saw a split Purolator.

On someone's post on here I've used them since prior to 2010 and have cut them. I've never personally had one.

Red (standard) - 96.5% at 20 microns
Blue (PureOne) - 99% at 20 microns
Gray/black (Boss) - 99% at 25 microns

All per the Purolator website.

^^^ I believe the BOSS use to be worse efficiency than that in the earlier years after it came out. I'll have to see if I can find any historical info. Anyway, 99% @ 25u isn't bad, and the BOSS has nylon mesh reinforced media so they will never tear.

It seems like everyone is cheapening filters these days, so Fram Ultra still looks like one of the better ones out there.

Are the red cans decent filters?

Yes, they are fine.

I'm going through this now due to a bad bad cut on my finger Saturday evening. Took 50 minutes to stop the bleeding. Then another 10 hours to stop slowly seeping.

OT but still important: no matter how bad the wound, all bleeding stops eventually…

Isn't that funny the one with the lowest efficiency costs the most.
