Best oil bypass filtration?

[janssen_nicholas]

I know about the amsoil, fleetguard, and filtration solution's fs 2500 kit. Which of these is best for the money...or in your opinion the best period? Let me know of any other kits that you know about that you might think is worth buying... Any feedback would be appreciated!!

Amsoil single bypass filtration systems are good but in my opinion stay away from their dual by-pass system. The FS-2500 is excellent but expensive. I went with the Oilguard unit and like it a lot. But I didn't use their hoses I had hoses made up similar to what Amsoil uses. You'll have less leakage from them. Just my two cents.

When you say single bypass filtration systems you mean like the BMK-11?

Why is the single bypasss filtration system better than the dual bypass like the BMK-16?

Yes...the single by-pass unit (BMK-11) that Amsoil sells is okay. It'll do what you want. I have heard and believe this is true that the dual by-pass unit have a oil flow restriction problem when used in the powerstroke. Just think about it. Look at your full flow oil filter you are using and look at the size of the openings. Now imagine pushing the same volume of oil through 3/8" oil lines. It is my feelings you are going to have flow restriction problems. Besides there is nothing wrong with your current full flow setup. You want to add a by-pass unit not a flow flow...right?

"Which of these is best for the money...or in your opinion the best period?"

When I was looking independent testing results lead me to the
decision I made. I was looking for the best unit I could verify with
independent testing and not "opinions" or "hearsay". I wanted data.
My idea was to give my engine the best chance for durability. I didn't
like the idea of wanting to spend $ on power enhancements and then
try to piece together the cheapest filtration system that I wasn't able
to verify it's effectiveness. Personal preference for a specific goal.

I have the dual filter set up by Ams, and I never thought about the flow restriction.
If this does cause restriction, it may cause other problems, such as loss in fuel MPG, due to loss of oil pressure?

Makes a lot of sense. Thank you for explaining.

I am not sure it would cause a loss of MPG, but it might cause wear problems. There is a pressure relief valve built into the oil filter header assembly. If it senses an over pressure situation some oil would by-pass the filters. This I feel would be the most likely scenario. Which means some unfiltered oil would bypass the full flow and bypass filters. Again...this is just my opinion. I have no proof this is actually happening...just a guess. Bottom line I feel it is best to keep it simple. There is nothing wrong with the original full flow filter setup...so why replace it. Just add the bypass filtration system of your choice and be done with it.

so i'm guessing you are saying that all of the bypass systems out there are pretty much the same? with the exception of the fs 2500 which is a little pricey, but tests show to be more efficient?

[Griz]

If I was to rate the three bypass systems you mentioned I would rate them in this order; FS-2500, OilGuard and then Amsoil. But is there enough difference between FS-2500 and the other two to justify the added expense...I can't say because I didn't want to spend that much on a filtration system to find out.

Ok, not to get into a pissing match with the GRIZ, but as far as my research as enlightened me, the Amsoil Dual Remote filter with the Amsoiler is probably the best setup. I don't know the numbers off hand, but there is documentation to back me up on this. Per pass of one quart, the one filter is where most of your oil is filtered through, like 75% down to something like 10 microns. The other filter gets the remaining 25% down to .001 microns. Now I may have stretched the numbers a bit because I can't remember everything that I read, see, or hear. But you get the just of it. I can't imagine any flow restriction, all I can picture is better flow with a little getting super-filtered on the side with every pass of oil. Now what was the selling point for me on the Amsoil set up was the Amsoiler add on to the filter kit. When your engine is running, a solenoid opens a valve into a chamber, the chamber fills with oil under pressure. When you shut the engine off, the valve closes and traps the oil under pressure then, releases the oil assisted by a spring when you turn on the ignition key. No more dry starts!

I am currently installing the dual remote filter setup with the Amsoiler on my '97 f-350 7.3L and plan to never change my oil again! Every six thousand miles or maybe more, I am not sure yet, but I will change one filter or the other and add oil to make up for what came out with the filter. Along with filter changes, I will do the oil analysis on a scheduled basis. This is what our military does with their motor vehicles and to me, the biggest thing of all, IT REDUCES OUR DEPENDENCY ON FOREIGN OIL!!! However slight it may be, I don't like funding 'THEIR SIDE' when I am fighting on this side!

I really don't like to argue, but I think Griz may not be 100% informed about the way the Amsoil set-up works. I am by no means an expert myself! But I like the way Amsoil Corp. has everything set up. The way they test and document their products, the thought and science that goes into their products. I think Amsoil has been ahead of the times by 30 years for 30 years! Here is a link to a friend of mine who introduced me to the product, and he is way more knowledgeable regarding the dual filter and Amsoiler. He can give you the exact numbers. Tell him Dustin sent you. MYLO at Lifetimeoil.com

Bypass systems aren't supposed to flow the full oil usage of the engine. THey flow a small amount only. Flow rate is really irrelevant as long as it flows some.

Also, pressure is not important to bearings at all. Flow matters, and the pressure needs to be high enough to get past all the filters and bearings, but that's it. I design some large bearing lube systems, and they are set up so the oil drips into them at atmospheric pressure. THere is a hydraulic system, but it's only there to get the oil to the bearing. In these systems, the pressure is equal to the sum of the pressure drops for the individual components.

In engines oil pressure matters because as bearings wear, they flow more oil and it's a sign of a weak engine. For lubication purposes though it's not important at all.

I don't know which bypass is the best because I've only used Oil Guard's for 5 years. Originally it was a great system BUT the owners sold out last year and the new owners raised the replacement filters from 3 for $39 to $24 each. Not cool in my book but I'm stuck with buying them at the new price. Something to ponder before buying an Oil Guard.

In agreement with mgraveman. The bypass filtration is exactly that, BYPASS. The normal oil pressure and pathway for the engine remains viable, the only difference is that a small amount of oil is bled off through the bypass filters to super clean the oil. After some amount of time (dont remember right off) all the oil will eventually go through the bypass filters and get cleaned better than just the main engine oil filter. It doesnt restrict the main oil flow to the motor, doesnt change the pressure or any of that. It runs off a separate block port to the bypass system independant of the main oiling system. AMSOIL is good stuff, used their products for years, along with Mobile 1. Not a gig for AMS, but they would not put a product on the market that doesnt work right.

Still cheaper than the amsoil ones at 37.65 each.
