6.7L Cummins Forum

Been doing a little researching bypass filters specifically FS200 vs Amsoil and wanted to see actual data points and efficiencies measurements. Please NOTE, I wanted to see ACTUAL 3rd party lab tests.

I am knocking either filters or knocking bypass filters, they are needed especially if you post injection process cleaning. I was focused only on FS-2500 and Amsoil, nothing else.

FS-2500 vs Amsoil ...

To date not seen any data on why one is better than the other besides people says so. Forget the dog and pony video on which can clean a sample better than the other .... People tend to lean toward amsoil because it claims 2 micron filtering and fs2500 claims 2.78 microns. Well there is a lot more to filter besides claiming a rating, there is an efficiency factor. That is why a proper filter is listed with efficiency like 2 micron at 98.9 percent efficiency. Amsoil from the best that I can find, OEM's their filter from Donaldson, they do not make their own as claimed by some sources.

I have not able to find that data with amsoil nor able to talk to anyone to get details. Yeah I can look at the Donaldson site and get details; however, I want 3rd party lab tests. I posed the question to FS2500 and got proof, an independent lab result which I wanted. They also provided comparison tests which is more that I asked for.

Attached is a test report showing flow efficiency vs micron rating over time. The other is test against the FS2500 filter alone.

Basically, at 3 microns, the fs2500 is 99% efficient at a 20 minute constant flow rate and the amsoil eabp110 filter (90, 100, 110 all the same, just different volumes) is not measurable, it fails.

This is why the standards for filtering includes efficiency to make it fare across the board. So while the amsoil filter claims it can do 2 micron, its for short burst from start, and the fs2500 does 3 microns for 60 minutes as the testing requirement.

There have been claimed the filters for amsoil are cheaper than FS2500. According to online prices, FS2500 is $27 (qty 1) on average and the Amsoil is over $38.00 and as high as $54.60 (qty 1).

The kits cost are a different thing (FS2500 can be as high as $650.00 and Amsoil with same braid lines $350.00). Both kits depending on who you contact can be had for roughly the same price. I will post soon a supplier and cost for the FS2500 shortly with a "No drill / completely bolt-on kit".

I will say this, the FS-2500 is built HD service, no chance of puncturing the canister any time soon. The FS-2500 is greener, just an element change, no canister. Depending where you install the Amsoil kit, you may need to add some protection.

NOT looking to start a flame war. Those that have Amsoil bypass, not knocking your setup. I am looking strictly at facts from labs that we can call and verify the results !! Nothing speaks better than facts, that is what I am after.

I hope people find this information useful and helps clear things up a bit.

Cheers.

There's no doubt (never has been) in my mind that the FS-2500 is a better more robust unit. But there is a bigger $$$$ difference than you state. The Amsoil unit, ready to install, is right around $250 CDN + $45 CDN for the 110 filter. The FS-2500 is $609 USD + shipping. Then there is the availability of filter elements and parts if necessary. The Amsoil distributor is local and the FS-2500 consumables will require shipping. The other factor is once the Amsoil unit is installed you are not locked into using Amsoil filters. As for as the "green" side of things go, it's a wash. The metal is recyclable, which leaves the element to be disposed of in both cases. The convenience of the spin on is a big plus.
As far as mounting goes, these things have to be in the engine compartment, in this part of the world. All that winter slush, summer mud and stones etc. can't be easy or good for the unit.
So, the way I see it, the benefit of the FS-2500 comes down to efficiency only.
JMHO.

As I said, both kits can be had for roughly the same price online. To be fair to everyone, costs are all based via online purchasing. Sales tax, shipping, and possible VAT left off since it varies per person. Just looking the raw cost. Installation will vary also based on location and personal preferences.

Yes, up front online costs for the FS-2500 is expensive, no argument on that. But since I know it can be had for roughly the same as amsoil kit online, tossed out that point.

Yes the green part is wash, however in some areas, some locations have restrictions on oil filter disposal, that is all that applies toward. Not a comparison criteria, just a mention.

As for the statement of not locked into amsoil filters, true. However is you look for spin on bypass oil filters, not many around. Bottom line, you are still limited, unlike normal full flow oil filters. Then when you change the filter, you change the comparison criteria. So again to be fair, compare apples to apples.

I am comparing FS-2500 and Amsoil and replacement materials coming from vendor. Amsoil filters are more than FS2500 based on online prices. In some area you can get lucky and get amsoil materials cheaper than others and vs versa. Again, that is in some areas and for some people (not a far comparison). The above prices listed can be verified by anyone.

If we put aside what the we can do in terms of pricing and look strictly at filter facts, then this statement sums it up:
If you purchase a filter rated at 2 microns and said filter is tested and fails at 3 micron after 20 minutes of usage and is only efficient at 10 minutes of continues usage, then you are not getting what you paid for and not getting the full protection you should.

If you purchase a filter that is rated at 2.78 microns and tested to be still 99% efficient after 60 minutes of continuous usage, then you are getting what you paid for and getting the protection you should. It is filtering more out on a continuous bases vs short period of operational time.

There is a reason why some vendors do not state the efficiency number. When the efficiency number comes into play (as per filtration measurement standards), you find out how poor an item really is and whether it is worth purchasing.

I agree with everything you say but I have not been able to find an FS-2500 at a price anywhere near the Amsoil. My points were not meant to be argumentative. I just wanted to give another viewpoint and alternatives. If I could buy the FS-2500 for the same price, I'd certainly go that way and stock up on filters to save on the shipping and duty.

DWR, Did not take as a argumentative point, sorry if I came across wrong. As an engineer and researcher, do not deal with people much and there is a reason at work they keep me behind closed doors My writing skills when dealing with people are rather poor.
