So help educate a new guy who can't see the comparison test
Well, this is a LONG, on-going debate about bypass filtration. There are basically 3 camps: Toilet Paper, After-Market (amsoil, oilguard, etc), and DIY (Do It Yourself).
Without bringing back too much information and debate, I can boil my argument down to this (which is 100% unbiased, no opinion what-so-over, never argued my point before this very moment..
)
I feel that the toilet paper and amsoil systems are not cost effective. Toilet paper elements DO A BETTER JOB at cleaning oil then any other option. However.. I say (and this is where the debate will NEVER end) that the submicronic filtration is pointless. A human red blood cell is 8um (8 micron) in size. Wear metals are around 15um. You really don't want particles bigger then 15um floating around in your oil. Most full flow filters are 15-25um. This particular B50 bypass filter is 2um nominal and 8um absolute (or so the ratings say).
If, for example, I was using a toilet paper element.. I had 7,000 miles on a highly fueled and modified diesel engine. I imagine I would be replacing my toilet paper every 3,000 miles.. Maybe 3,500. That means, I would have had to replace the toilet paper 2 times and add 2 quarts of make-up oil. A quart of synthetic 5/40 is about.. what.. $5? That means to have nearly no effect on engine wear, I would have spent an extra $4 (give or take) on this oil change interval alone....
Isn't that much dough, no doubt. But, lets say I owned a fleet of vehicles.. Then it starts to add up.
I'm fond of amsoil products, just not their price. Amsoil would probably also product marginally better numbers then the B50 on the particle count. But, their elements are $30 a pop!! No where near cost effective. Most other after-market filters that require a pre-made element are going to do the exact same.
The cost benefit just isn't there with the other filter options, IN MY HUMBLE OPINION. Toilet Paper is the best bypass filter you can purchase, but the cost to operate for what little difference you get in engine oil cleanness is a mute point.
To prove my point.... Here is a HUGE compilation of particle counts using various other bypass filtration methods. The smaller the number in any of these, the better the job the bypass filter is doing. As you will see, there are a few filters that will do better then the B50 (or B164). But, we can discuss how much installing a B164 and the upkeep for it is worth compared to any of these options listed.
Am I being provocative? You bet. There are a lot of highly intelligent people on this board that I fully hope come in here and pick everything I have posted apart... That is the beauty of this whole site. Everyone is entitled to their opinion, and you will learn more here then you could anywhere else.... Plus, it's a cold, wet, miserable day at work.
Quoted from MSPARKS:
This three-part number is an International Standards Organization Code to illustrate the level of cleanliness of the hydraulic fluid in the unit. The numbers are logarithmic representations of the total number of particles greater than two (2) microns (first number), greater than five (5) microns (second number), and greater than 15 microns (third number) in a one milliliter sample. The larger the ISO Code, the more contaminants, the more potential for wear.
IN ORDER TO INSURE PEAK PERFORMANCE AND EXTENDED OPERATING LIFE OF THE MACHINES, IT IS RECOMMENDED THAT AN ISO CODE CLEANLINESS CODE OF 16/14/11, OR BETTER, BE MAINTAINED REGARDLESS OF SYSTEM PRESSURE. THE OIL CANNOT BE TOO CLEAN.
added in edit: Note the above statement is for hydraulic sytems which are about 100 times cleaner than combustion engine. Hence the reason my ISO code is higher than the recommended. I feel that my ISO code is very good as it's pretty darned close to the "standard" for a hydraulic system.

Frantz bypass filter. Amsoil full flow filter on the left, fleetguard filter on the right. Says both runs are approximately 5,000 miles.
Frantz Bypass Filter, 15/40, 9000 miles:
ISO Particle Count: 17/16/13,
Particles were:
>2 micron = 1,666,
>5 mu = 617 mu,
>10mu = 170,
>15 mu = 66,
>25 mu = 15,
>50 mu = 1,
>100 mu = 0.

That is most of the particle counts and information I could find on the site. I HIGHLY encourage people with particle counts to post a comparison.
