Oil Filter Thread

[Burla]

I'm not saying there isn't one, but I am asking if there is an iso for paper filters or blends at any interval. Because it is information I do not have if it exists. The iso's I have read are on construction and a bunch of tests when new and mimicked with load- particle dust. But non that test the filter in use with cycles of hot oil and how the binders held up. I want to know the rational of Mr filter saying paper is good at 10k, he must have a reason he said that. Certainly he must have a point over my pay grade.

Nothing... So no data exists on any paper filter on a long interval or any interval. Even 1,000 miles can be hard on a filter. If the truck drives ten miles a day, that's 100 days, what will that paper filter be doing at 1,000 miles? I'm pretty sure we know or except synthetic mainly spun glass doesn't degrade, doesn't even stiff at 2 years 10k miles, by my own hand.

The primary testing standards for oil filters are outlined in the ISO 4548 series, which specifies multi-pass testing to evaluate filtration efficiency, dirt-holding capacity, and flow characteristics. [1, 2]
The specific ISO designations for testing and rating lubricating oil filters include:

• ISO 4548-12: The standard for multi-pass filtration testing. It determines a filter's efficiency at removing specific particle sizes and its overall contaminant capacity by continuously injecting test dust into the fluid. Many high-performance filters achieve a near-perfect efficiency rating (e.g., 99% efficiency) at 20 microns using this test. [1, 2, 3, 4]
• ISO 4548-13: Specifies methods to test the structural integrity of oil filters. This evaluates the filter's ability to withstand static pressure at high and low temperatures, burst pressure, and points of failure. [1]
• ISO 4548-7: Focuses specifically on structural integrity by testing a spin-on filter's ability to withstand harsh engine vibrations. [1]
• ISO 16889: While primarily used for hydraulic and industrial lube oils, it is an international multi-pass test standard that evaluates filter efficiency and dirt-holding capacity in a highly controlled laboratory environment

Wow - that's going down the rabbit hole like back in working days.

Just like the lube oil companies, many oil filter manu's have stopped publishing data once they learned how the interwebs were sharing it to determine best products for various platforms.

So unless somebody knows of more tests, the few tests there are were done while oil filter makers were buying and selling and changing designs. Who knows if what they claim is true or not.

Too bad Fleetguard Stratapore/Nanonet and Donaldson Blue synthetic media filters have little to nothing for consumer engines.

What about at real world mileage?

6k or 8k miles.

My 6.4l manual says change the oil at 8k. I do it at 6k

... And the filter too.

Since some members want to hear what zee says on filters such as Puro Boss, this is what he says on Carquest EP. So before running EP over another filter, consider this if you like what zee says more then engineer testing. He prefers a paper filter over Carquest EP at 10k miles. Again, if he is Mr filter I just want to know what tests are done at the end of a filters life that causes him to recommend paper. Any ISO for that? I have looked, I cannot find that.

Could assume the holding capacity of the EP is twice as high than the Premium because it's rated for twice the max mileage. For the Carquest EP, at half loaded (10K miles) it would be 96.5% @ 20u. So if the EP is only 1/4 loaded at 10K miles if loaded at the same debris rate to its max mileage rating, then the efficiency would be better than 96.5% @ 20 at 10K miles, but I don't think it's going to be as good as a fully loaded Premium at 10K miles, or at any point. Running the EP to 15K miles as you mentioned above, the EP will still not be as good as the Premium at 10K miles. But the EP efficiency is still pretty good for a 20K mile rated oil filter. Better than some other oil filters rated to 20K miles, like the Boss, Purolator Gold 20K and the Mobil 1 Extended use.

For the 2 pennies it's worth, Burla still says run syn filters even at 10k miles. He is comparing a paper blend versus poly. I call bull that at 10k miles paper filters are anywhere near iso testing on new media. Not a overwhelming positive post, I wonder what he thought of the old spun glass that were running stats til they ended. He does say he likes Carquest EP over boss because of what a spec sheet says. From what I have been able to ascertain their is not an iso test for paper media at the end of an interval. One might use common sense that a filter that uses binders and paper in a hot oil environment simply isn't going to be as effective at 10k versus no thousand miles, but there is a lack of actual data.

Zee says use Carquest premium over EP on 10k interval.

mr filter says Carquest premium for you.
