New member with oil filter story

Hi everyone. Long time lurker but newly registered. Thought there might be interest in this failure of the well regarded purulator filter I found on another auto forum. I make no judgments either way about the product. Just an example of how bad luck I guess.

interesting...

Every filter manufacturer is going to have an occasional defective filter. They should however stand behind their product when that's brought to their attention.

Wow never heard of that before.

I have 2 on my dual remote.

I once bought a Motorcraft filter that didn't have any threads to screw it in. That was an easy return. Like TJ said, every manufacturer has an occasional defect.

I wonder if Purolator would compensate you for consequential damages (pay for the engine rebuild).

 

[Gary Allan]

He should be able to send them the filter. It will be obvious that he didn't loosen the seal to cause the separation. If it did result in damage, he should have a relatively easy collection process.


..or so I would reason. I don't think that there's any way to "fake" a failed crimped/rolled seam (or whatever the process is)

Any manufacturer can goof. I'm amazed at how many filters they make for such a small amount of slip-ups. That being said there are some other considerations.

I don't know how this filter failed, but filters do have a time/mileage limit for a reason. Depending on how the filter is constructed it could eventually fail if left in service too long. One example could be the type of adhesive used to seal areas of the filter. Also certain materials are designed to last longer like the silicone vs. nitrile rubber used in the anti-drainback gasket.

AMSOIL uses a silicone anti-drainback gasket for longevity in their EaO oil filters, but orange Frams use nitrile rubber. This is expected since the two filters have tremendous differences in the time they are designed to remain in service. But the Mobil 1 filter uses a nitrile rubber anti-drainback which is surprising considering Mobil's new attitude toward extending oil drain intervals. Yet the Fram Dual Gard uses a silicone anti-drainback meaning it could be designed for longer service intervals.

If left on way longer than the rated service interval any filter can fail.

I would think that this could have lawsuit potential.

"But the Mobil 1 filter uses a nitrile rubber anti-drainback which is surprising considering Mobil's new attitude toward extending oil drain intervals."

I believe the Mobil 1 EP oil filter's do use a silicone anti-drainback valve in their construction.

They do.

I have a Dodge 5/4 ton that runs 100 psi of oil pressure, due to a high volume pump, I have Split the Fram and supertech filters, but i have been able to get the WIX and the Napa Gold filters to hold the oil pressure

You are right, Mobil 1 does use a nitrile rubber anti-drainback gasket. Here is more information. Granted, this information could be outdated. Maybe someone else knows something. None-the-less I was disappointed that an upper tier had ever used the nitrile rubber! Here's a link:

That study is so outdated it's not even funny. Champion hasn't used nitrile ADBV in the M1 filter in years. They use silicone.

(You really do need to stop posting and start reading.)

Start giving us something to read. I would welcome that. However, I still say that I am disappointed that the Mobil 1 oil filter EVER had nitrile rubber anti-drainback seals. If they have changed that great! Where did that picture come from? It appears that they are using silicone now.

Start giving you something to read? There are currently over 945,000 posts on BITOG. You've got more than enough to read already.

I am a cynic when it comes to what a person says about something. I've been burned too many times. I really like to see better information. That picture you posted speaks volumes with a disassembled Mobil 1 filter. But if someone says they are using silicone with nothing else I just take it under advisement.

I have had people, usually other mis-informed AMSOIL Dealers, tell me that the Franz toilet paper filter did not filter very well and would channel unfiltered oil. I believed this and one day a guy selling Franz took strong issue with me. First call I made by phone for more information was to the AMSOIL Technical Services for more information. Guess what? They let me know that the Franz toilet paper filter filters exceptionally well and even gave me technical specifications on that filter. I had to apologize to the Franz guy and it just left me with egg on my face. Reading information posted gets my attention better with links to something credible to back it up. You have to admit, even with credible information, things still aren't what they seem.

But we're just supposed to take you misinformed posts at face value, right?

 

[TurboJim]

Gremil in that study you have linked to Wix also used a nitrile anti-drainback valve. The website was last updated 11/10/03. I think they're overdue for another revision.

 

[wsm41bn]

yea, a wix doesnt use a nitril ani-drainback valve now

 

[DOHCtor]

Hummmm interesting... Working at a local autoparts store, i occasionally see returning defective filters... mostly FRAM and some Quaker state, Bosch, etc... but we also sells a lot more frams than anything else so....
