Oil filter revisited

[Vaughn MacKenzie]

You guys are not gonna like this but...

Fleetguard filters don't filter very well.

But, they do flow well. I would only use one in conjunction with a bypass filter.

I always got excellent oil analysis numbers running Stratapores, even running 20,000 miles between oil changes (although I changed the filter twice during the interval). That tells the either the filter is working well, or the wear is so low the filter doesn't need to work that hard at "cleaning. "



By the way what is the LF3679 filter?? It looks different internally than the Stratapore pictured in the TDR article Joe D. referred to, which matches the description EEdmundson posted. I would pick flow over filtration performance anyway, what good is it to have really clean oil if it has a hard time getting to where it needs to go?

Has anyone had an oil filter fail?



Has anyone had poor oil analysis running "other" filters?

As I mentioned earlier,

Do you remember the infamous whiteknight fiasco? Perhaps the single most famous story at the TDR.



Bottom line: if some part of your oil filter causes engine damage, it'll be a LONG time before it's resolved.

As I mentioned earlier,

I went through that thread and missed the relevance.

Dealer said oil filter failed, denied claim

Fleetguard said oil filter did not fail

Oil sender circuit has flash that shows 40 lbs with zero pressure (??)

D/C pays for motor R&R



I was asking if anyone had a filter (any make) that failed, burst or caused engine damage.

In all of my years I have never had a filter failure nor have I ever herd of one. When I use to race, I had seen a few oil filters that were ballooned outward from the high volume oil pump and the high RPMs. But no outright failures. I know some have had leaks, but most of those can be traced to improper installation. I think the oil filters like oil brand is just something people like to personalize. Truth be told, there is not alot of difference between the cheap and top brand filters, just how much you pay. I call the manufacture I purchase from (we sell filters by the case) and they have all been certified by the sanctioning bodies, and stand behind there filters performance with written warranties backed up by insurance policies. Air filters are the same, I inquired about them as well. Yes there are many filter brands to choose from, but very few filter manufacturers. Most all make filters for dozens of popular and off-brands, they all come off the same assembly line, just get a different coat of paint. Truthfully I do not feel it makes much difference which brand oil or air filter you use, but the change interval is most likely the important item to remember. Many like to push the intervals up, but diesels are the dirtiest engines for oil polluting, and are very well the ones least suited for extended oil change intervals. Gas engine on the other hand are much cleaner and better suited for extending the oil change interval. We have so much soot, it just doesn't make much sense to push the drain intervals out past the recommended levels. And oil analysis is a huge waste of money, yes it sounds good and gives some a leg up on their friends, but who needs it? Why pay 14-18 bucks to have someone tell you about your oil?? Just change the stuff and get on with it. Everyone worries (or so they say) about filters, and yet they run around with coal black oil because some clown tells them it looks good. Of coarse they are going to say it's OK, if they didn't know one would have it analyzed. You don't send out for a report before you wash your nasty rear do you??

What I meant was, IIRC the final cause of the problem was a faulty oil pressure regulator which caused a massive spike in pressure which blew out the oil filter, which then destroyed the engine.

I thought the oil filter remained undamaged and the source of the oil leak was unfound.

Or the high pressure blew by the seal and the stout F/G filter held fast?

Certainly pressure spikes like that are a consideration!!



I'm really concerned about the "show 40lbs pressure when zero" thing. If I can verify that one, my truck is getting an oil pressure gauge soon. Is D/C really that stupid?

Had one explode years ago; don't remember the brand...

The spring is for the bypass, to release during overpressure. The better filters all seem to use a stainless coil spring. The cheesier filters usually use something that looks like -^- .



.

That spring is what seals the filter to the can and is just how it is built... the bypass is internal in most engines.



I'll stick with a Mopar approved filter... anything else is just being lazy. I am running mopar filters currently, ran Purolators and fleetguards... frams were NOT approved. I really don't like wix as they appear cheap when compared to something like a purolator or fleetguard.

Back from the dead...

I did a little searching tonight. The mobile guy told me a while ago that the M1-403 is made by Purolator. Pruolator's website subs the M1-403 Mobil filter to a Purolator L45335 found here: Filter Specifications . It's also the one on the approved list. So IF the Mobil filter is indeed made by Purolator, it should be good to go.

I still don't like the fewer and smaller holes in it though.
