Oil Filter Pics (Draw your own conclusions)

Since I started this project it is scary to see how many failed oil filters come off of the vehicles coming in to the shop every day. I have confirmed two orange Fram's have failed in less than 5000mi this week. They both had the media pushed through the center tube. Not as bad as the pics but there was 1 hole in one and two in the other. The holes were both in the area that Fram's distort in near the lock seam after use. Every Fram we take apart is distorted and damaged around the lock seam, and the ADBV is always rock hard on anything with over 5000 mile drain.

All of the Wix are great filters. I did take apart 1 Napa silver (Wix) that was used on a very sludgy motor and extended drain that the paper had turned brittle and coated with sludge, there were 16 breaks is the paper.

Also of great concern were two Champion built Dodge cummins filters we chopped. Both were damaged where the paper meets the endcap on the closed end. It was torn away from the endcap on three different pleats. I have noticed that Champion seems to be building these filters in two factories. They look totally different inside. We switched to Fleetguard (stratapore) for all heavy duty applications about a month ago.

Also wanted to note that the clicker bypass is a POS. I cant understand how they are supposed to work. It is my opinion that they don't. I hope our new e-core design is better.

Not to bag on other's businesses but from what I see most of our competior lubes use Fram's disguised under many different names like Security, Defense, Mileguard etc. These things are all junk and represent most of the failures we have seen so far. It's too bad that these chains have most of the market segment. There are a lot of innocent people out there suffering premature engine wear, sludge buildup, etc. due to the junk filters but just don't know anybetter. Most really don't care either, they are more concerned with getting it done in 7 minutes rather than 10-15.

Sems there should be more of "looking at used filters where a little of the oil change history is known" done.

thanks

what causes the failures?

1.? oil gets old and thick and blows out the paper element

or

2. heat gets to the paper element over time and weakens it.?????????

as in if I change my oilevery 4 months but dont drive a lot can I let the filter go every other change (wix) or will it blow out too. even tho oil is changed regularly - only 1000 miles a month driven

EdwardH1,

I think you answered your own question. I believe filter failure stems from long drain intervals and the exposure to heat and pressure and the filter plugging,(due to the long drain interval.) The paper I see in most filters after an extended drain is extremely brittle. It easily cracks and tears in your fingers. I see this caused by heat and pressure. The nitrile ADBV is also very brittle and hard after long intervals. The sludge is what seems to really do them in though. Once the paper is brittle and the sludge packs in to it it seems to eat away at the paper, maybe the acid builup in the oil. At this point the cartridge starts to twist and deform, especially in cheaper filters, and holes begin to tear and punch through the center tube like Fram's do. I have also seen many tear away from teh endcaps like I posted previously.

About the Purolator, they seem good. It is surprising how many Factory installed filters are manufactured by them. Motocraft, Mopar, come to mind. Aftermarket filters sold under these same names are NOT what comes OEM installed on the vehicles though. It is a mixed bag. The only thing I see as a possible problem with the Purolator type filter is the string around the media. It seems to create a sawing action through the paper, especially after a long drain interval. Recently I have even seen a few Champions using the string around the paper and the paper was slightly damaged in a few. The pleats seem to move around a lot in filters with uneven media spacing and this creates this sawing action and the paper may eventually be compromised. i do want to note that this condition is extremely rare and I think the Purolator and its clones are good filters.
 
Lubeowner,

Have you ever cut open a higher end filter (M1, Mann/Mahle, Amsoil, etc.) from a severely neglected vehicle? I mean one where, let's say, somebody blindly went 18-24 months & maybe 25-30k miles on the same oil & filter?
 
lubeowner, thanks again for sharing your experiences and observations.

MAybe this is all why Toyota sez on 04 up models to change oil 5000 miles or 6 months.

That Seems a reasonable compromise between the 3000 mile jiffy lube folks and the 10,000 mile extended people.
 
wavinwayne,

From what I have seen all of the Euro filters (Mann, Hengst, etc.) on cars using high quality synthetic oil will stand up to the long drain intervals. the pleats are always evently spaced with no distortion and silicone ADBV are used and are as soft as they day they were new after 15000 miles. Personally I would not go past 10-12,000 miles, but I know somw of the BMW and Mercedes have factory recommended OCI of 15000 miles, and I believe in Europe they go even longer.

As for domestic applications the best filters I see are Motorcraft and Wix. As I posted earlier I saw a badly damaged Wix a few days ago but it was used on a sludgebucket. The filter was totally plugged, I don't blame this on the filter and I think that no matter how much you spend ona filter if you neglect the oil change it will eventually fail. This is my experience, anyway.
