out/off: 8 quarts HPL PCEO 5w-30 with Fram Endurance FE10575

in/on: 8 quarts HPL PCEO 5w-40 with Carquest Extended Protection P84502.

terrible leaf spring on this one. on another note, this truck has burned oil since we bought it used. hoping the carbon in the bottom of the filter is coming from the ring area.

Great work and pics. Cleaning is happening. Thank You sir

Looks like it came out of a diesel!

Thanks for the great pics, especially the ones of the leaf-spring--I've seen a few recent posts that mention the rippling of the metal on that leaf-spring and wanted to see it myself. I'm also using this exact filter for the first time in my new truck.

So, I'm trying to make sense of how that rippling will significantly effect filtering.

Oil at the top of the filter (above the leaf spring) is pressurized at whatever pressure it's at from the auto's oiling system, less the (pressure) drop across the filtering media, which should be significant. The oil will take the path of least resistance and in theory most of it should flow through the media, correct? I get that some oil will flow through the rippled metal at the top of the filter and by-pass the media, but is that amount of unfiltered oil going to be significant to the overall performance of the filter? That oil that passes through the defective leaf-spring will come back through the filter and eventually get filtered, no?

It seems that this defect would more directly effect the the operation of the by-pass valve by changing the pressure required to activate it, but in that case, the leaking around the ripple wouldn't matter, would it?

FRAM should do a better job with their quality control, and the OCD part of me gets tweaked a little by stuff like this, but at the end of the day, does it really matter? Thoughts?

I think some are worse than others. Calculations on one of mine indicated 15% of the oil bypassing the media.

Yup--that spring looks pretty ratty! I hope they fix their QC! Other than that spring, the Endurance filter line seems pretty solid based on the pics I've seen, as well as the specs. --Rob

Based on a leaf spring gap measurement by @Glenda W. (think it was the one in the 2nd photo in post 16 above), the calculated flow past the media would be around 15% ... that's a pretty bad case. If the ruffles on the leaf spring are small and the gap is small, then it would be less flow percentage bypassing the media. Yes, any oil that leaks past the media will probably get filtered on the 2nd or 3rd time around, so that's something people need to decide if they are "OK" with or not. Personally, I don't want an oil filter that is in a constant 15% bypass mode. Full-full filters aren't suppose to be "partially full-flow" filters.

Agree 100%.
It’s a “defect “ but not enough to make a difference and override this superior filter and overall construction.
I don’t subscribe to “15%” is bypassed .
Whatever is bypassed initially is immediately filtered anyway.
I will continue to use the Endurance.

 

[ZeeOSix]

^^^ As said, if the gap is bad like the one measured then is would be around 15% bypassing. Less of a gap means less percentage bypassed. The bottom line is a "full-flow" filter isn't a full-flow filter anymore when that much oil can bypass the media.

This is my first go-round with the Endurance filter. Is there a guestimate here (Bob's) about the frequency of that defect? The Endurance is already installed on my truck, so I'm gonna run it for an OCI and then cut it--if I find it defective, then I'll be done with them. Meanwhile, I don't expect that this filter will be demonstrably harmful to my engine. At worse, really poor filtering efficiency.

I had my daughter finish a 5k oci. Just an efficiency hit that cost me $13. A guesstimate is 75% of First Brand filters have the defect, the degree of the defect varies.

Originally before First Brands, Fram Ultra’s had a seal between the leaf spring and end cap and the leaf springs were smooth. It’s like Fram knew this was a potential problem area in design.

Holy cow. . . worse than I'd thought! How does that happen in manufacturing these days? Geez. I've been reading a thread from earlier this year that addresses this topic--I should have researched it a little better before buying, but I have to admit that I'm kinda biased toward FRAM stuff and got comfortable with just going with it.

On a related note, it seems that most new filters from any brand have design or manufacturing defects that are objectionable to BITOG people. . . I used Puro's years ago, switched to FRAM due to media tearing, and now FRAMs having issues. I know that most mainstream filters are made by two major players here in the U.S., both of which seem to prioritize profits above customer satisfaction. I think most people on these forums would gladly pay a little more for a quality filter, but the average person doesn't know / doesn't care and that's what's driving the market.

If you shop Walmart the new Mobil 1 filter is very nicely made now. Advance Auto has the Carquest Premium and EP. O’Reillys has the Microgard Select. Any of the Premium Guard filters are top notch.
