Fram Endurance FE10575 C&P

[RobbS]

Those always come out looking good from my Jeeps, too. (cartridge). But I have seen 1 ppm more insolubles consistently compared to the Fram XG in the Pentastars, when I've done the UOA's. Not a big deal. I bought 12 to 14 of the Mobil 1 filters on clearance at Wallyworld 5 or 6 years ago for $3 each. I think I have one left. They've served well.

That's awesome.
I'm proud at how mechanically profound my cars run, smooth as butter.
I've used these EP filters for decades performing 7k mile intervals. No problems.

What was the mileage on that OCI? If the leaf spring was a decent leaker, the oil cleanliness is going to get worse as the OCI is increased compared to if it wasn't leaking dirty oil past the media.

I believe he said 12k oci with HPL. I’m also wondering if this is a good example of a leaky Endurance? Admittedly I’m not familiar with particle count interpretation.

I'm not familiarized with what are the common or suggest target ISO cleanliness code of engine oils. I did a quick search and found some sources. One from Donaldson, which of course they have a very strict target cleanliness. And another chart showing common ISO cleanliness code ranges for a range of hydraulic applications. Funny enough the particle count that @BrendanC FE10575 actually meets the typical ISO cleanliness rating of 22/21/18 per Donaldson from his WearCheck particle count results.

And it could have been better if there wasn't some dirty oil leakage going on. Maybe his had a relatively small leaf spring leak. I look at the actual particle counts because there are pretty large count ranges between the ISO codes.

^^^ BTW, getting some magnets in the mix can also help reduce the particle counts in the lower size of particles, as you know.

I think we're both in agreement that the problems lies in the Media Element assembly design and not the filtering media material itself sourcing from all recent discussions of the bad metal to metal contact leaf spring seal and bad stamping quality would throw off filtration performance targets.

From the looks of it, the Fram Endurance is looking more or less like a 10K mile filter than a 25K one if we're to condemn the fluid by target cleanliness ratings than just by typical oil analysis conditions such as TBN, Oxidation, Wear Metals & other contamination readings.

Then again this is just one sample size to draw a conclusion on...
