FS-2500 bypass oil filter ?

[AH64ID]

The FS-2500 is absolute (98. 7% efficient) at 2. 78um, the Amsoil filters are absolute at 2um. Therefore the amsoil should filter better, and its cheaper.

The video they show on the FS website is misleading. Thats not soot like we have in our engines, its much larger particles. Then you have the oil we run that is designed to keep soot from agglomerating, this makes the wear from soot less, but also makes it harder to filter.

Cummins limits on non-EGR ISB's is 2. 75-3. 25% soot.

I question the cost of doing/putting on the system,then changing filters and adding oil. . How many miles per year or how many times are the changing of filters and cost of sample testing VS going Dino oil/factory filter and doing 3 oil/filter changes per yr,buying 3 gal oil at walmart (Rotella) 39$ and buying filter 9$ at dealer-48$ X3 =144$ a year at (5,000mi/per change)=15,000mi per yr... . this is not oil vs oil I was just looking at the cost per yr because avg. person will sell or trade truck for a new one before the other one will go to bone yard. .

I am $160/year if you go that route. . But I get a min of 20K miles out of the oil. . So if you add one more change to your math then its cheaper.

A bypass filter is not for the average person. The average person will rarely service his/her vehicle at all. A bypass filter is for someone who actually cares about his/her vehicle and wants to keep it over the long term.



The filtration numbers speak for themselves. If that doesn't persuade you to see the benefits of a bypass filter, then cost certainly won't.

i have the fs 2500 but on the 08 model fuel dilution in the crankcase kills the mileage intervals, so synthetic is too expensive to change frequently. rotella and valvoline work well. as oil levels climb up the dipstick from egr regens etc. FS2500 does not catch the smallest carbon particles either.



i have done oil samples and the fuel dilution crankcase levels climb on the 6. 7, due to regens at a fast rate , below 10,000 miles tops and that is really pushing it

I guess I'm not the average person, because I have generaly kept my vehicles at least for ten years. As too the By-pass systems, I have had one installed for tthe past 7 years on my 03' truck, and have yet to pull the drain plug, with 90K on the truck, and 81,300 miles on the oil! I installed the system and the oil in April 2003 with 8,700 miles onthe clock, system still on and oil is still in good shape. Viscosity at 14. 6 cSt@100F. Soot level is 0. 3 Percent, TBN is at 6. 44. Wear metals are very low!

It is true, By-Pass systems and oil sampleing are not for everyone, but for me it is a no brainer! Because all one can determine by looking at the oil, is the color and the feel... ... ... ... ... ... period!

IMO, bypass filters with conventional oil are a hard to beat combination... unless you actually need the "durability" of synthetics, today's conventional oils work very well with bypass filtration.

How are you all that are running bypass filters judging when to change your filters? I am watching the return flow on the downstream side of the bypass and changing it when the flow drops off. Then changing the regular oil filter somewhere between 5k and 10k miles. a sample annually depending on how many miles I run. Then pullingJust curious what everyone else is doing.

 

[steved]

My GCF was a 10k change interval... so I'd change it at 10k and the fullflow every 20k.



This baldwin I'm going to run with synthetic oil 20k, then dump the oil and change the filters. I'll do a couple UOAs initial, then just run it.



I did UOAs to keep track of the GCF, and verify it my interval and methods worked.

 

[flyby night]

Can you dumb it down for me a little. I don't pick up on the abbreviations that well. What is it that you are referring to as GCF?

 

[steved]

GCF is Gulf Coast Filter, a type of bypass. I installed it, completed several UOAs to ensure my change out was working, then ran it (without further UOAs).



No bypass should be used to extend oil/filter change intervals without completing several UOAs to ensure its working as it should.

 

[AH64ID]

I change mine based on UOA. About 25K for my full flow and bypass this time.
