Amsoil Two Micron Bypass Filter Kit

[RHestand]

I just finished inst. the above kit yesterday.

I have three questions about soot particles in engine oil.

1. Are they smaller than two micons?

2. If they are, what size are they?

3. At what point do they diminish the oil's lubrication ability?

My truck's oil was honey gold for the first thousand miles or so, then it turned totally black and stayed black. I've changed oil & filter (both Amsoil) every ten thousand miles.

I now have thirty two thousand total miles on the the truck and the new oil turns black as soon as I start it.

I'm going to send in my first oil analyses in at another ten thousand miles.

If that comes back good, maybe I can stop being concerned about the black.

Old habits are hard to break. (Clean oil on my dip-stick)

Thanks for any replies on this.

Thanks,Ray

I share your feelings with Black Oil. My first CTD was a 2000. I changed oil about every 4K miles. It would be a dark honey color when changed. I now have a 2006 and the oil turns black within 50 miles of oil change. I followed all the threads I could concerning this subject. It appears as this is due to the new common rail emissions configuration which puts the soot into the oil versus the exhaust. It is kind-of-like Cummins taking one step forward and three steps backward. Those who have had their oil tested have reported the blackened oil will not harm the engine. Hard for my mind to comprehend but I don't know what else can be done. I tried the Frantz toilet paper oil filter but this hasn't helped either. This reply isn't much help to you but I hope you feel better about the black oil not doing damage to your engine...

Mmerlino,



I'm left wondering if the difference in your 2000 vs 2006 CTD oil color was due to a more aggressive use of EGR between the model years? From what I think I understand, the new model engines use a CEGR ( cooled exhaust gas recirculation), that greatly increases the amount of soot that is mixed with the fresh air. This soot, along with other contanimants, is the major cause of engine wear. Adding this soot to the combustion process only increases the amount soot blowby causing a dirtier less effective oil.



It appears that the new CJ-4 oil is formulated to bind certain by-products of combustion in the exhaust stream so these particles can be trapped and oxidized in the particulate trap in that exhaust system. In order for the oil to do this, some beneficial wear additives had to be reduced in the CJ-4 oil in order to prevent clogging of the particular trap.



If I'm wrong in my understanding, I trust someone will state it correctly.



Regards, Richard

I think the cooling manifold started with the 07 6. 7. But the newer 5. 9s sure do turn black quickly.

Flyfishing,



I do not know for sure why it turns instant black, nor do I truly know what the difference between 2000 and 2006 is that produces this instant black. I do know that I don't like it... I keep reading the oil analysis results from others with the same black oil and there analysis all seem to prove out the soot is not harmful. This just doesn't seem to compute...

Flyfishing,

Thanks for the link, great article.

I will copy and save.

This is what makes TDR such a great place.

1) Soot particles are smaller than 2 micron; however, at that size, they pose no problem.



2) Soot is generally smaller than 0. 1 micron. It is when they agglomerate (stick together) that they cause a problem...



3) Soot particles agglomerate, which uses up additives... by removing agglomerated soot from the oil with the bypass, your additives last longer. Also, agglomerated soot particles can become "abrasive" if left in the oil too long... a bypass filter helps prevent this from occurring by removing the agglomerated particles...



The black oil is the nature of these 2004. 5+ trucks... it is caused by a third injection event for emissions reduction. A bypass filter, at least the one's we have access to, will not keep your oil "honey brown" clean for very long... my Gulf Coast keeps the oil clean for about 3k, then it too becomes progressively darker.

Most soot is less than 1 micron in size. According to the testing labs(like Blackstone) most of the damaging particles are 3-7 micron in size, and your typical oil filter catches particles in the 20-30 micron range. Having the bypass system is one way insure that your oil stays free of the worst element... . large solids.
