ops1 vs fs2500

Ordered mine from Harrison Truck Center Freightliner near Waterloo, Iowa.

Plus....

 

Wow that looks great maybe for my next truck I will consider this. Congrats it looks awesome and I never considered having a Columbia but those colors look good.

 

I also have the FS2500, very happy with it. Very easy install, and easy to service. Another plus with the 2500 is, when you change it you can see the filter media. The OPS is a spin on, it has to be cut open to inspect the media. I think the OPS is a spin on.

 

Great point on the evaporators masking a small problem. Glad you pointed that out. I'm leaning towards the FS2500 myself.

 

I side with anyone getting something to help filter the oil down. Use a spinner II, gulf coast, OPS, FS2500, Amsoil, whatever, just do it. They all do a great job and with the soot that these engines are creating internally, stock full flow filters are just not good enough anymore. Bypass is very cost effective, even in the short term. Even if you don't extend the drain intervals, which one probably could. The bypass is going to filter out a lot of small stuff that will get thru a stock full flow filter. A stock full flow usually filters down to 15-21 microns. Most bypass units are 98% effective at removing stuff down to less than 2-3 microns. It is the 4-5 micron range that particles can start creating abrasion in an engine, especially in bearings.

If you want a simple, clean, fast install, the FS2500 wins. And they recommend you change their filter at 10,000 miles. Forget that idea. I have gotten great results taking the FS filters to between 15,000 and 20,000 before noticing the soot level starting to rise a little, and then the soot level was still less than 1%. They make the bulk of their money selling filters, like most of the bypass folks. No use spending more than you have to. If you are one of the folks who feels best changing you oil at 25,000 miles or less, then use only one FS filter for the entire oil change interval. Take a look at the filter when you change it. Man, it catches a lot of crap. And the nice thing is, you can see the surface of the filter. If you have super fine metal particles being worn off inside, you can see it on the surface of the filter media.

 

call filtration solutions or go online for the fs2500. on my third truck with system and enjoyed the simplicity of installation and service. always have good oil samples and customer service is great.

 

Ops is not a spinner
It filters down to 1 micron

 

Most all claim to filter down to 1 micron, but it is the effective flow rate that makes the difference. Actually, in the fine print, you will find that they actually say what percentage they filter down to 1 micron. Usually something like 90-98%. Either way, it is just academic. particles do not become a problem till they reach the 4-5 micron range. So any bypass that filters 100% down to 3 microns is going to do the job just fine. But marketing is what it is, and all the bypass units make some form of grand claim about how they are better than everyone else and you will lose your engine early if you don't use their bypass system. I would much rather have a bypass that filters more oil in an hour that filters 100% to 3 microns than another filter that does not filter as much oil per hour but does so at 1 micron. The effective flow rate can have just as important, if not more so, than whether the filter got every little 1 micron particle.

Keep in mind, the bypass unit is only filtering about 10% of the oil, or even less, in the time frame that 100% of the oil has gone thru the full flow filters. There is a lot of oil that will always have contaminating particle in it. You can't flow all the oil thru the bypass all the time. hence the name... bypass. So there is no way that the oil in the sump is filtered down to 1 micron all the time. Now if you can run more of the oil thru the bypass in a period of time, and catch 3 microns, it is conceivable that the oil is cleaner in the sump than a very slow filter is getting oil thru at 1 micron. The finer you filter, the slower the process and the less oil you get run thru the bypass in a given time frame. So don't get all caught up in the "we filter to 1 micron" marketing stuff.

 

With all dues..
If such was the work of the by-pass (as you state and point it's title) then there's no point in buying a filter that would only filter 1 gallon out of a 10 gallon engine. (Per your 10%)

At a $700/900 range (parts and install labor)
Plus pulling samples and paying for extra oil every month to "fill what's wasted on filter changes" the filter @ 10% efficiency is not a good investment at almost $1000+/- the first year.
Now, if it says on paper it filters down to 1 micron (which is superb) and with results of 1-3 microns will be the performance of the unit you'd buy
- not like all cats give 6.7mpg and have the exact same measure internals

I'm neither fav'd of a particular unit. The bypass filter works, buy any of them

Btw I thought coolant could not be evaporated, is that so?

 

What he's saying is correct was in the literature of the Amsoil bypass kit I installed on my pickup. In the time a bypass filter has filtered all 10 gallons of oil the full flow has probably filtered that same oil 10 times over. Takes the bypass about 15 minutes to filter 3 gallons of oil in my pickup. So if I always started and stopped the motor in 10 minutes or less not all of that oil is going thru the bypass. But who does that?
