6.7 CTD Longevity Compared to 5.9 CTD

6.7 CTD Longevity Compared to 5.9 CTD
Upon seeing how quickly the oil gets dirty in the 6.7 ltr engine I was wondering if the large amount of soot is in some way detrimental to engine longevity. Does it cause excessive wear of the bearings, cylinder walls or other parts of the engine? I would imagine the oil filter clogs up pretty quickly with all this stuff floating around in the oil, too. I would hope that the particulates in the oil are softer than bearing material and therefor inconsequential but that still doesn't address the question I have about the oil filter element getting clogged. Obviously, I'm not a diesel mechanic but I have experience with industrial machinery so I'm not entirely in the dark when it comes to equipment maintenance. Thanks in advance for your comments...

If you're worried about it, get an FS2500 bypassfilter (www.fs2500.com) or similar brand. My buddy has a bypass filter on his PoSD and it works great. His uses toilet paper rolls for the filter medium (no kidding!). His oil looks as good as new after thousands of miles of use. Of course, that 6.0 can use all the help it can get .

a bypass setup will NOT stop your oil from turning black. the black is the soot particles in suspension.the oil is doing its job. the fs2500 will trap smaller micron size particles than the spin-on, but it wont keep the oil honey colored.

He said it was easy to install, didn't ask the price. His oil does look pretty darn good compared to mine. Not quite honey color but close. Oh well, at least black oil is easier to read on the dip stick .

The oil in my last four vehicles has been black
(2) 2001 Jeep Gnd Cherokee 4.7l V8
2001 Dodge Ram w/360
and now the 6.7L
I am curious as to what parameters the 6.7 uses to tell the user when it needs changed. I wonder if it's just a timing/load thing, or if it actually has a sensor somewhere in it.

What's the 7.3's secret for keeping the oil clean? I thought all diesels blackened the oil...an inquiring mind wants to know...

The newest CJ-4 formulation was more for the particulate filter on the ultra low emission diesels. They basically lowered the levels of the some of the additives in the oil to keep it from clogging up the particulate filter. Same thing goes for the formulation of ULSD. Dang EPA.

Somebody on here (on another thread?) was blaming it on the 3-4 injection events allowable by virtue of the common rail technology. The 7.3 and 6.0s are not common rail, therefore the oil looks cleaner. Doesn't mean the engine will last longer though....

i have an amsoil single bypass set up on my truck. i can change the oil and run around the block ( 2 miles) and my oil is as black as night!. has to due with the third injection event.
