Exactly.

And, obviously - one that doesn't stay in place!!

Wouldn't any filter work like that to a limited extent?

Unless very tightly controlled, there will be some narrow passages in the medium so some fine filtration will occur, but will it be significant?

A poster in a similar thread suggested (I think correctly) that their door screen had better than 0 efficiency at 2 microns, but it probably wouldn't be significantly better.

I guess they all have variable pore sizes it's true. So the best filter over a long haul should be the one that has the finest pore structure, in some amount, as well as the large for flow. Well I tried.
 
You are welcome. I bought two on sale to try them out. Their cartridge filters are not ready for prime time. The green pre-filter is stretched over like an air filter from an ATV application. In this day of online forums, poor customer care is not a good plan going forward. This filter needs a wire mesh cage to capture the foam pre- filter. Essentially the foam is un-supported. Just my .02$
 
And, if they are promising the same 30,000 mile OCI procedure as they do with the spin-on filters I think it weakens their claims. If the cartridge filter really can accomplish the same goal then, to me, it reduces the "specialness" of the bypass disc filter. I've been using MG for three years but never paid much attention to the cartridges since they did not offer one to fit my GF's Lexus.
 
I have to say I had great results with the mg on my Chrysler 300. The numbers from blackstone were awesome with the microgreen and royal purple combo. However the Mobil one and wix was something to be desired. They have a code for Amazon gives you 10% off and I believe they have lowered the price if anyone is interested. The code is THPMAR17 it gives you a discount.

The TBN of both UOAs is very interesting.


Nothing in that report is attributable to the filter.

You sound definitive about that.

On what basis do you make such a definitive statement?

Changed two variables at the same time. Only thing that really went down was the iron PPM. Doesn't Mobil 1 always come in with higher iron counts?
 
Copper went up significantly.

And TBN vs mileage was very different.

It's safe to say that TBN depletion went down significantly.

And we don't know which grade of M1 was used.
 
I used mobil one 5w30 regular ,I attribute that to the filter by the statement virtually no contamination in the narrative of the report. the royal purple was also 5w30 I thought it was pretty interesting. However, i did not use the same oil but i am a purple fan. i am doing another on my nissan 08 8000 mile interval one with wix and one with the mg I just sent the wix one off and am using the schaffer 5w30 syn on both would like to see how they measure up. Being as fram has purchased champion labs i will only use wix, hastings, and MG

That comment about "contamination" is referring to fuel, water or antifreeze. None of which are effectively removed by the filter.

As ZeeOSix mentioned you changed two things at once so no one knows what affected anything. Besides, the wear metals shown in the report are not something that is being filtered out.

Of course I don't know, but it is closer to what you say you know. Actually I am pretty happy to probably have figured the thing out even though it is very simple in concept. I thought it was a gimmick but keep an open mind towards things that they may have had some idea. A partial fine and partial coarse filter works like the separate disk, think about it. I don't legitimize any company. I have complained about the closed ADBV situation to them with no response. Putting motives in other people's minds is not a good practice.


Like ZeeOSix discussed it cannot work the same as the sintered Teflon disk, that's impossible. The filter would be in continual bypass.


Agreed, I haven't looked into their cartridge line to much but I dont see how it could make the same claims.

The outer element could be made to work like the round disk on their others. Whether it does is another story. I think from their stated work they did more than put foam around the filter and called it a day.
I would worry if the foam filter contacts the canister walls and inhibits flow more than anything else.

Nice. Got any technical or well reasoned comments?

I'll order one that theoretically fits my sprinters take a look at it and report.

There are a bunch of ways they could make it work, but Ive paid little attention to cartridges while my MB's ares under a factory service plan.

It would work if the foam performs depth filtering effectively.
Also, if the foam shifts down, it looks bad, but think of what actually happens to the fluid flow:

---Fluid Path "A" travels through the main media (not the foam)
--------Path A is low resistance, so like a parallel electrical circuit, most (say 99%) passes thru Path A here.

---Fluid Path "B" travels through the scrunched-up depth foam, high resistance, low flow (like 1%)
--------Depth filtering thru the foam allows small engine varnish or sludge particles to lodge inside the foam, increasing filtering of smaller particles over time.

Notice how the 99% "A" path flow, and the 1% "B" flow parallel path actually resembles the teflon disc method.

The only question is how effective is the foam at grabbing 2 micron particles? I think it has to age slightly in the presence of carbon, varnish, and sludge particles to allow it to capture the small 2 micron stuff in the later half of the oil change interval when its really needed the most.
