Oil Bypass Filters

[River-Runner]

Hey Guys,



I've got the 6. 7 and the soot levels in the oil just can't be good for this motor. For the folks using the bypass filters, I'd appreciate any feedback. If you do oil analysis, is your bypass filter keeping the soot levels down?



Once and for all: Does the bypass change the color of the oil back towards amber?



What bypass did you install and picutures of where you put it would be great.



Thanks much.

I think to get the oil color back toward amber you have to filter to the submicron level (filter better than 1 micron). Gary's Frantz oil filter will clean to sub micron level. That is the ONLY one I can ever recall that will actually change the color of the oil.



I run a RACOR LFS-802 that filters to the 2 micron level. It does nothing for the color of the oil.



As I understand it, and someone correct me if this is not correct:

The bearings etc can tolerate particles up to 5 microns as particles that small will literally pass through the bearing without damage. Over 5 microns is where you start getting damage to bearings etc.



I have been running the RACOR LFS-802 for some time (changing filters every 10k miles). I had my turbo rebuilt a few months ago by HTT and the rebuilder ask me what I did to the oil. He said that the center section was the cleanest he had ever seen in lots of years of rebuilding. There was virtually no wear to the bearings. I told him about the LS-802.



Does it help the color, no. Does it help remove potential damageing particles, yes. Is it "over engineered" yes, but that is what I do, do it once, do it right.

One micron is 1 millionth of a meter or approximately 0. 00003937 inches. So 5 microns would be 0. 0002362 inches. Is that enough to damage an engine bearing? Seems pretty small to me!

According to the (SAE) Society Of Automotive Engineers paper 881825, AC Spark Plug and Detroit Diesel Corp. performed a joint study of the relationship between the level of engine oil filtration and Engine wear rates, and found finer filtration reduced the rate of Engine wear.



Diesel and Gasoline Engine wear rates were established by building a Diesel and Gasoline Engine with fully inspected wear components and inspecting them after the test. In both Engines, the upper and lower main bearings, oil rings and compression rings were inspected. In the Diesel Engine, the cam lobe profile and cylinders were also inspected, while the piston pin bushings, piston pins and cylinder liners of the Gasoline engine were inspected.



The total test duration was eight hours. To accelerate wear, 50 grams of AC Fine Test Dust was added, in slurry form, to the crank case every hour.



Diesel Engine wear tests were performed using filters with high efficiency ratings for particle sizes: 40 Microns, 8. 5 Microns and 7 Microns.



Gasoline Engines wear tests were performed using filters with high efficiency ratings for particle sizes of the following sizes: 40 Microns, 30 Microns and 15 Microns.



ANALYSIS



The researchers found clearances in the Diesel and Gasoline Engines varied between 2 and 22 Microns during engine operations. That means particles in the 2 to 22 Micron size range are most likely to damage Engine parts. Particles smaller than 2 Microns will slip through the clearances without damaging bearing surfaces.



CONLUSIONS



The researchers drew the following conclusions:



Abrasive Engine wear can be substantially reduced with an increase in single pass efficiency. Compared to a 40-Micron filter, Engine wear was reduced by 50 percent with 30-Micron filtration. Likewise, wear was reduced by 70 percent with 15-Micron filtration.



Controlling the abrasive contaminants in the range of 2 to 22 Microns in the lube oil is necessary for controlling Engine wear, and “The Micron rating of a filter as established in a single pass efficiency type test, does an excellent job indicating the filter’s ability to remove abrasive particles in the Engine lube oil system.



The smallest particles most popular “full Flow” filters capture with high efficiency are sized 25 to 40 Microns, depending on the filter brand.



I utilize the Asmoil "By-Pass system" (BMK-11 and EaBP-100 Filter element) and do oil analysis every 10,000 miles. My last analysis with just over 60,000 miles on the oil and just under 5 years (Aug 2007) reported 0. 76 percent SOOT/SOLIDS.

Is the oil "BLACK"? Yes it is black, and it has been black for the last 55,000 miles! The first 5,000 miles on the oil with the by-pass the color of the oil was pretty clear, but as I said it has turned black since.

The "Color" of oil is not necessarily an indicator of how good the oil is.



Used Oil analysis is the best indicator of serviceability.

Thanks Guys:

I had one of those Frantz bypass filters on a 69 Cougar I bought used in '73. Bought it with 93K miles and sold it with over 150K with a solid motor. I remember the oil always looked clean. I think I used a 2K change cycle on the TP and qt of replacement oil.



Sounds like both of you are happy with these two systems.



Wayne, What is your change cycle for the spin on bypass unit or do you depend on analysis for a change cycle? How much does a EaBP-100 cost?



RWeis: What kind of oil do you use? What do filters cost at 10K miles? Is the replacement filter a spin on or cartridge?



Gentlemen, I appreciate the feedback. I love this new truck, but just don't see how dumping so much soot into the motor via the EGR system without trying to get it out is prudent. I've got a feeling Dodge will come up with a work around, I just want to protect a $40-something investment in the mean time.

The color of the oil does not have anything to do with how clean the oil is. Virtually all oil uses a detergent that will turn black at around 200 degrees. The Frantz will remove the smallest solid particle which is soot. Take a match, light it, let the flame get onto some glass. Now rub your finger on the glass to remove the soot. That's how small soot solids are. Put a little oil on your finger and you can wash it off.





If anyone is interested in any Frantz Filters, I have some used units I will let someone have. You pay the shipping.

I depend on the oil analysis results to determine the filter change interval.



I have changed the filters 2 times in the time the oil has been in the truck.



1st one was done with 31,000 miles on the oil, 2nd one was done with 45,300 miles on the oil, but was done due to high copper reading, which turns out to be most likely from the oil cooler. (typicle of some ISB's) EaBP-100 is bought at the wholesale price since I am a dealer.

I use the fs-2500 bypass and so far am very pleased with it. I have had just one analysis so far and everything looked great. I am going be changing the oil and doing the analysis at 8000 miles this time. I'll see what thenumbers numbers look like then.

I have only 11k on my 6. 7L. The change oil indicator came on only 2300 miles after my last change. Since my G30 flash the indicator has not come on. I plan to take an oil sample the next time it comes on just to give me and the dealer a base line to compare with the indicator. I plan to add bypass filter soon. They can only help.
