Motorcraft FL-820S (Purolator) 10,000Km

[OVERKILL]

This filter has been sitting in my basement for a while. It was the Redline 5w-30 run in the Expedition from April 14th, 2011 to August 27th, 2011.

After all the Purolator hysteria on here lately I figured it might be a good time to cut this one open. Truck currently has an FL-820S on it as well.

The tear-down:

Biggest gap (at the seam):

Rest of the filter (even pleats):

No tearing at the seam area:

Excellent filters - Looks good!

The Purolator filters have tears are the one with metal crimp at the seam.

Currently I don't have any Purolator, I used the last P1 about 2 years ago.

Thanks for posting this. Do you know, or can you determine, if the Purolators with the tearing problem have the same filter media as Motorcrafts?

Purolators and Motorcrafts don't use the same media. The efficiency of them is different, and I'm betting the media in the Purolators is more stiff and brittle than in the Motorcrafts, which is one factor on why it tears in some cases.

Or maybe it's more flexible and easily torn.

How nice it would be for readers had you some facts to go along with your speculations.

Or maybe the metal crimp at the seam is causing problems, along with wide pleat spacing.

The Motorcraft filters are made using media spec'd by Ford, so that is probably a key difference.

I ran one for 15K on my FX4 and it looked like every other one that I removed at various mileages. It seems the MC filters have dodged the Purolator issues (if there is indeed a wide-spread issue).

Have you ever cut open a Purolator and actually played with the media by putting side force on it to see just how stiff and brittle it is? I have, you obviously haven't. BTW, I found this tear way back in 2011, and I kept using Purolator filters since then. But now there seems to be a huge up-tick of reported tear incidents.

Based on what I've seen, I'd bet the Motorcraft filter media is more flexible and resilient than the media in the Purolators.

Note the text:
"The media seemed too "brittle" and I could make it tear easily by simply just pushing the pleats sideways when spreading the pleats apart for debris inspection."

What do you think of that tear ... trivial and not a big deal in your mind? A failure? ... definitely.

I have two thoughts:

- the tear is trivial.

- you need to find an outlet other than bashing Purolator for your need to attack something.

And that teen is only "a little bit pregnant". A filter with a whole is no longer a filter, it has no more purpose.

This is BITOG. This IS our outlet. This is the place WE get to say something and find our own answers, and not just put up with useless liability-conscious market-speak from manufacturers.

 

[EA82]

Im convinced, motorcraft is the best bank for the buck.

I take it this means I am allowed to disagree with you.

So far the only answers have been ungrounded allegations of doom, destruction, and despair based on tiny tears. On the other hand, someone actually took the trouble to analyze his oil after finding some tears:

This tells me that even though tears are...or even minimal

and noted that the effect was apparently nothing at all.

A few facts to go along with the shouting would really be helpful.

Seems like your whole motive on this chat board is to go find someone to disagree with. You must like conflict and arguing.

What's your real agenda here?

"The tear is trivia."

Just an Ostrich with his head in the sand. If you think I'm "bashing" Purolators you're hallucinating. I'm stating facts, these tears happen and it's being discussed. Show me where I've said to everyone that they shouldn't use a Purolator. There are many here who say that themselves based on the information they have seen. Maybe you think all the reports and photos are all fakes. Wouldn't be surprised if you did actually

 

[KCJeep]

His agenda is overwhelmingly obvious, denial to the point of incredulous.

What are you Wilhelm, a paid Puro posting henchman?

 

[Merkava_4]

^^^ Yeah, this Wilhelm_D dude sure goes all Rambo over Purolator.

 

[KCJeep]

On the other hand, the UOA looked fine. So do a whole bunch of Honda/Toyota UOA's using OEM filters with absolutely abysmal efficiency.

So I'd put forth the notion that the lost efficiency on the torn Puro's is not a huge deal. But torn media still is. Or Puro can just keep their heads and the sand and make the most of it.
