Bypass micron rating: How low to go?

[96stroke]

I am going to be putting a bypass filter on my truck. I was given some filter heads and a myriad of mismatched hydraulic filters from a company that was cleaning out some old inventory. These are high end filters with a Beta rating of 1000 (some 2000, not that this really matters).

What size are the additives in oil? This arises because some of the filters given to me are 1 micron Beta 1000 and 1/4 micron Beta 20. Looking at bulk molybdenum dithiophosphate, it appears to be in the 1/2 - 1 micron range (when new)

How low is too low on a micron rating? I do not want to strip any additives out of the oil. Filter changes due to clogging are not an issues because they were free!

You won’t strip out additives.

Amsoil claims that filters can't filter additives

I'm planning to regularly clean the oil of both my car and motorcycle through a fine 1 micron filter. After hearing of stories where filters strip additives from the oil I contacted Amsoil to ask them if my 1 micron filter would strip their additives, here is the answer: Quote: Stefan, No filter...

Here are some previous threads on this topic:

Can bypass system filter out oil additives?

I vaguely remember a blurb from the NORIA website that stated that bypass sytems can sometimes filter out some of the good oil additives???? Anyone know if there is any truth to this?? Thank you.

Can you have too much filtration?

I have heard that the super-fine grade moly used in motor oils measure .5 to 8 microns in particle size. The baldwin HPG filters claim to filter down to 3 microns. Would this cause a problem.

Ultra Fine filtration and additive stripping

A while back I withstood humongous fury from several board members for my relating additive (namely VI Improver) stripping with the use of a 1 micron beta 200 filter in a real world application. And that it appeared to be VI improver stripping which the oil formulator of the oil shared can be as...

by-pass filtration

I purchased a Harvard 500L filter to use for by-pass filtration on my GM 6.5TD. The filter and housing holds 12 qts. increasing my total oil capacity to 20 qts. The system is supposed to filter down to 1 or 2 micron. I am wondering whether I am better off not installing the filter and...

Additives filtered out

With all the additives we are dumping in our engines, SLOB, CD-2 75K, VSOT, etc. and oil filters getting better and more efficient all the time, can't some of these additives get filtered out? Plug a filter?

kschachn, some of the articles/links you provided directly contradict the "you won't stip out" stating that most of the anit-foaming additives are in the 3-micron range.

Yes, I agree that most of the commercial bypass systems filter poorly and are at best Beta 20 (in reality Beta 2) at the 1 or 3 microns they state. However like one of the threads mentioned, when you get into a Beta 200+ filter you can start removing additives.

It does seem plausible to be able to remove needed additives by over-filtration.

Not sure about the lubricants side of things, but we definitely have had some of our NanoNet filters strip out fuel additives and lubricity enhancers from diesel fuels. Something to consider when you get down to the low single digits in micron ratings.

Any motor oil additive in solution is going to have a mean diameter far smaller than the VM present in the oil. If you’re adding some sort of solid material that stays in suspension then I might be worried. But anything in solution cannot be filtered out

Has anyone done a decent analysis of the "sediment" I see settled out in the bottom of Pennzoil jugs?

Is it just "really fine" calcium carbonate, or...????

I think anything added to oil is needed - - and:
anything that settles out - - - can be filtered out

But the fallout hours back into solution once hot.

not if you don't shake the jug well before pouring the oil into the engine....

What is in that stuff, anyway?

Keep thread up!! Like the references the one guy gave and searching for bypass filtration can be tricky… I used to have an oil guard bypass filter in my Honda accord2004 and my brother sill drives to this day… good luck with truck…
