Engine/Transmission (1998.5 - 2002) The FS 2500 Bypass oil filters

[MTatsch]

I got to reading about the fs2500 bypass oil filter and it seems pretty good but go to www.FS2500.com and tell what yall think or if you already have let me know how the work and if worth it

I run an alternative: RACOR 802LFS. RACOR = Commercial / industrial filter. Just another option.

I got to reading it to. I purchased and installed the unit about a week ago. My oil seems to be getting more transparent but it is still black. I had about 2500 miles on the oil (amsoil) when I installed it. I was looking for a quicker cleaning of the oil. I only have 100 miles on it so far.

LOTS of sub-micron particles will make your oil just as black as the bigger stuff - just less damaging to the engine...

 

[drury]

They work. I have one, and I don't have any regrets about it. Your oil will still be black though because your engine is putting out smaller soot particles than the powder they use in the video. There are lots of alternatives. If you like doing maintenance on your vehicle every 2,000 miles, the Frantz Toilet Paper bypass filter probably does the best job of filtering, and the filter elements are as cheap as they come. If you don't like doing frequent maintenance, then the FS-2500 is a good choice, but probably not the cheapest.

How much are the FS2500's? If anyone is interested in pictures of my Amsoil bypass filter mount on my truck, let me know. I think I paid around $200 for the mounting bracket, and about $45 total for both the filters. I'm 100% happy with my Amsoil kit. The mounting was easy and I don't seem to have any oil starvation problems. I'm a fan!

 

[Duluth Diesel]

The FS2500 is about twice as much as the AMSOIL system.

 

[MTatsch]

yeah the FS2500 is about 500 and the filter is 25 or 30 but if it get most of the soot out of the oil and if you can longer before changing the oil than it will be worth the buy

 

[rweis]

When I was all about distance between oil changes one of the TDR members put it this way:



"Changing the oil is like flushing the toilet"



Eventually I came off the distance between oil changes as it was more expensive to get OA every 3k, time to make sure the additative package was "good", cost of the synthetic oil.



I hope you have better TCO than I had.

I do bypass oil filtering. Change oil and engine filter every 5k, bypass filter every 10k.

 

[Cummins Pilot]

I've been thinking about a bypass setup. I'm concerned with the fact that I tow in the winter (read -40f or colder) and the cold oil in the lines running to the bypass will not move. How close is the bypass filter to the block/how long are the oil lines?

 

[Duluth Diesel]

As for cold temp performance, a conventional 15W40 may thicken up quite a bit in the bypass lines and filters. AMSOIL 15W40 has a cold pour point of -44 degrees Farenhiet, and their 5W30 has a cold pour point of -58 degrees Farenheit, so cold performance and flow shouldn't be an issue. Run a good oil, and you will get the performance characteristics you demand.

 

[Partyat33]

If the oil 'freezes' in the bypass, so what. Its not going to hurt anything. When it warms up it will move again.

I talked with Chris at FS2500 and they have soem test data he says he will give me to put on the site, they had each system tested side by side and I will post the results here as soon as he gets them to me.

Believe me - it will only get the soot particles out above a certain size, and there WILL be enough remaining to keep your oil nice and black if you leave it in more than 3-5K miles or so...

 

[Ragain]

I am a firm believer in a bypass system. I run one on my Pete also. Original Cummins Big Cam 400 with nearly 3,000,000 mi. (I have in-framed it 3 times and replace rod/mains every year just outta habit). The soot particles are what does the damage.

Take an oil sample without a bypass system. Put some of the dirty oil on your palm and rub with finger... . black soot in the oil makes your hand black and hard to clean off. An oil sample in your palm with a bypass system may still look dirty, but when rubbed with your finger will become nearly transparent again and your hand will clean easier. Proof that it is doing its job!

I also send a sample into the lab periodically to check for any abnormal component wear.

If the oil 'freezes' in the bypass, so what. Its not going to hurt anything. When it warms up it will move again.

If its "frozen" what good is it to have when its not doing its job. I know it won't hurt anything, the rest of the system will work normally. Up where I live once the bypass system cools off to ambient temps it will never come back online. No flow means no heat. Last winter it was -56f for a week. Heck even my transfer tank couldn't pump out treated #1, I had to remove the aux fuel filter to get it to transfer to the main tank.



I run synthetics, 5w40 in the winter but pour point doesn't mean jack! Pour point & ability to be pushed thru small lines & filters are two different things. At work (aircraft mechanic) we use 25w60 in the R-2800 engines. It will pour at -20, very slow but it will pour. Its not going thru a filter until its warmed. I'll end up getting one but I'll have to design it so that maybe I will have some coolant lines running down the oil line & filter housing.



One side note, I used to run Amsoil 5w30, while good oil and a low pour point, its not going thru a filter at -44f.

 

[Duluth Diesel]

Agreed, Cummins Pilot. Filter plugging point is different than pour point, but pour point can be used to judge how the oil will perform in the cold. But in Fairbanks, Alaska, any oil will be tested to its limits. What 5W40 are you currently running?
