Bypass oil filter on a Re gen motor?

[BIGNASTY]

We have a piece of equipment it has the same thing that you guys with the Regen systems have on the 4th Gen trucks. It has an indicator that tells when to change the oil. If we were to put on a FS2500 Bypass (actually two filter canisters) would this effect the oil change indicator system. Does anyone with the 4th Gen Regen exhaust have a bypass filter? if so does or how does it affect the system





Thanks

The change oil notification in in the ECM. It won't know the bypass filter is there.

The big issue is fuel contamination with the 6. 7 and it can not be filtered out. Had a guy come in and complain because his 6. 7 showed 5% fuel contamination with his Amsoil 15/40 and dual filter set up with 25k on the oil. He insisted there was a problem. I agreed,lack of oil change at recommended interval

 

[BIGNASTY]

So your saying that the oil change interval indicator is looking at Fuel contamination! and not soot levels? that the bypass filter would take some of the soot out of the oil.

 

[Bob4x4]

The oci is to protect against fuel dilution. The premium diesel oils do a good job of keeping contaminates in suspension. I make no claims of being able to filter out small soot particles. IIRC one of the bypass filter companies had in the past, then changed it's story later.

The ECM calculates the oil changes from the duty cycle, how long, what load etc. From testing, the engineers have figured out when the fuel dilution will get high enough to be a problem. They have figured out how to program the computer for that. Actually, it "sees" nothing in the oil. It just knows what will happen under certain parameters.

Change the Knows to predicts and I wil agree

OK a guy learns something new everyday!!!!

So really a Bypass oil filter wont do **** for these motors because the oil will be changed BEFORE the filter could do its job!!

Exactly-except to line a filter companies pocket.
I have seen more problems due to add on oil filtration than oil related failures

Thanks Gentlemen don't want to screw this up would NEVER hear the end of it if I did.

Would you agree that a bypass filter will lower the soot level in the oil?

I believe that the fuel dilution issue makes the oil change necessary and the bypass can offer nothing to help.
So while the bypass does have a proven benefit, it is not cost effective in an engine that has a known fuel dilution situation.

while I am a fan of bypass filters, I will consed that a poor installation or part quality parts, can lead to more headaches than it's worth.

I don't know about the rest of your questions on the filters but the part about soot level in the oil

I send my oil in to a lab rat that tells me what the size of the soot is not how much soot is in the oil, This way my FS2500 I can tell if its actually doing its job of filtering the SIZE OF THE PARTICULATES, My oil is BLACK within seconds after a change and fire it up to check it out run it for a bit and let it sit, when I check the oil level it BLACK as if it wasn't changed. This is the BS that the FS 2500 people have in their advertisement showing the dip stick that you can see thru the oil on it to that I say B*** S*** and have told them as much. But the particulate size is what they claim. I also use Filter Mag on my OEM filter and have cut them open to see what if anything is caught!!! THEY WORK guess the Air Force used them for a reason.

I ran an Amsoil bypass for about 100,000 miles. It did not filter soot. My oil analysis proved it. There is a by pass system that will help with fuel dilution. It's called O. P. S. It has a heater in it that helps evaporate the fuel and even coolant contamination. I can't justify the expense on our trucks. Dino oil and 5000 mile changes for me.

Mine doesn't filter soot either unless the particle is bigger than 2 mic then it captures that. I have one of the OPS filters on my International truck I had a picture of it but cant find it. Mine doesn't have a heater its just a filter that actually does a pretty good job. The oil in the International actually stays amber, I have been told the reason the Dodge wont is that it has another injection event of fuel and that is what causes the extra soot build up, DOES IT REALLY???? HELL I don't know I just know it works according to the lab rat that I send my oil samples to

 

[BIGNASTY]

Someone was talking about the OPS system, I have one of the OPS 1 filters and had them send me a picture of it so I could show you what this one looks like. It filters to 2 or 3 mic and burns off the fuel and coolant contamination within the oil, don't have the info for it with me and wont be at our Seeley house for a long time but gives you an idea of what it looks like. Oil goes in from the top and out and the same way but then on the side of the filter housing it goes to another part that does the contamination burn off. Sorry for the blurred picture It wasn't me taking the picture. Borrowed this filter from where I used to work forgot that I had it but this was for trucks that had a RE-Gen system. I will take it back some day MAYBE!!!!!

If soot is your only concern, then don't bother with a bypass filter.



Yes, you need to change the oil more often because of designed-in dilution by fuel. But using a proper bypass filter will remove from the oil particles that are large enough to cause wear but are too small to be trapped by the full flow filter. This is the primary reason bypass filters are used.

Just a question, is Soot abrasive in the oil?

It appears that soot can be an abrasive contaminant. If the particles are smaller than the thinnest oil film bearing in the engine, they won't cause wear. But if the particles are larger than the thickness of the oil film bearing, one should expect premature wear. This is why I suggest it's a good idea to use a good bypass filter; it will filter out particles larger than the oil film bearing.



The full flow filter is designed to provide long life to the engine by removing the most harmful particles. But it's not 100% efficient at its design size. So even though a bypass filter only gets maybe 10% of the oil at any given time, it's enough to catch large-ish particles the full flow filter misses.

Spiner filters,they are a mini centrifuse that seperates solids from the oil such as soot,and they work. the liner in the spinning drum that collects the soot is a paper insert that cost about 2 bucks.

OK but the report does not mention the stock engine oil filters micron filtering capability. Or mention the oil film thickness on the bearing surfaces. I assume that the soot particle size has to exceed the oil film thickness to cause wear. This is critical information I need to make a decision to install a aftermarker filteration system that might not make any difference if I change engine oil at reccomended periods. Being a diesel mechanic and having torn down MANY HD diesel engines I have never seen a wear issue that could be attributed directly to soot load in the oil. My area is in agricultural engines, where dust ingestion is the most common issue causing premature engine wear. I have seen ag engines with 20,000 hours of running black engine oil and still going strong. And I have seen the same style engine that suffered dust contamination ruined in 100 hours.
