I just checked the oil on my 08 6.7 with 1450 miles on it and it is blacker than any diesel I have ever seen. Is this normal? Is it a new truck thing or a 6.7 or is this not normal. It isn't burning any, just super dark.
As long as you have that stuff on the engine. Also many people see the volume increase up to 3 qts between changes due to blow by when diesel is injected in on the exhaust stroke for the DPF. Good stuff right there.
Nope, he's saying that the diesel that's injected during the exhaust stroke during regen cycles makes it's way past the rings into your crankcase causing the oil level to increas by as much as 3 quarts. Thanks again EPA!
I did on mine till I was able to get all the emission stuff off my motor...
Its that or you better watch the oil level and not allow it to get over full to the point you allow the crank lobes to pound the seals out of the engine... Not to mention how bad the oil is going to break down and not lube the bearings well enough.
Actually dude this whole thing stinks if you ask more than a few of us on here. I am all for the clean air, b ut not like this and burning twice the fuel to get the clean air. All the soot you get packed in the oil on these motors with this EGR system is nothing more than a grinding compound for the bearings as the oil is pumped and pushed through the system.
With how thick and nasty the oil gets before you change it, its not going to be a pleasant sight for you since you have already noticed the color. Then with where your at in Anchorage, the temps are going to have this thick nasty oil even worse. The whole setup we have with all this emission stuff as it is, its all gloom and doom JIMO...
I sure hope they come up with something that works better for all this or take the guys that think this crap up, out and hunt them for sport...
My 6.7 is so much more happy with all this stuff off, oil is better, mileage is up and she is slowly getting simpler looking under the hood as I get rid of this over priced stuff...LOL
yeah that is my case, damn warranty! Take it off and something pops and I am screwed. What a crock! I swithed to dodge because I thought they had there squared away.
I have the fs-2500 and the oil is black as coal. My uao comes back great. The next time I send in a sample I will have 15000 miles on oil. 3% fuel was the most I ever had so I changed it. I can't remember what dodge says is acceptable.
A bypass filtration system will help reduce the soot load that your oil carries quite a bit. There have been many threads on here about the most popular bypass filtration systems, AMSOIL, FS, and Frantz. I'd recommend doing some reading about them. I'll put the AMSOIL system up against any of the others when it comes to filtration quality, efficiency rating and price. Your oil will still darken with a bypass system installed, but your soot load is greatly reduced and UOA proves that, as 2rowdy stated.
Bypass filtration is nothing new under the sun. Many many people, myself included, run a bypass filtration system and get good UOA back. It is a proven fact that when you demand a better oil and couple it with better filtration, you get better results and save money and downtime.
Has anyone done the DPF delete and the EGR delete and used a bypass filter yet? I know a few have but is the oil clearing up yet?
