Black Oil

[stevep]

I changed my oil about 1000 miles ago and it still looks Golden Brown... not black,..
i used Rotella T

strange,........... i wonder why ???

my old Volvo's in the boat the oil was black instantly

Today I did an engine flush and put new Amsoil in. 20 seconds of run time and it was as black as what came out again. I guess there is nothing I can do for black black oil on a 3rd gen diesel. I would like to know what it is that turns the oil so black so fast. Even the Amsoil dealer was surprised. Oil analysis says everything is OK though.

Thanks for the info Chuck... BTW I got the 189 today and will throw it in tomorrow. What type of oil do you suggest for the 06's ? Wanted to do some research on it. Thanks!

This was already answered. Soot. Newer engines have more EPA crap that creates more soot during combustion. This soot is sub-micronic, something like 1/100th of a micron. Really small. It gets right past your rings and into your crankcase which makes your oil black. I've used bypass filtration from Oilguard to Motorguard and now run Amsoil bypass and the oil is black BEFORE I start the engine when I check level on dipstick. It's normal, don't worry about it. Just have fun...

That means the soot is in the crankcase and does not all leave with the old oil correct? I had a feeling it was emission related, would that have something to do with the post injection? That injection of raw fuel on the exhaust stroke that gives the catalytic converter something to do?

It's not that there is soot in the crankcase. It's just that the old oil, which is black, is still coated on all parts of the engine. So when you pour in the new oil, it picks up the blackness (soot) of the old oil.

The third injection event supposedly happens to keep the cat hot. It happens later in the power stroke, I'm assuming. This contributes to more soot due to less efficient burning of fuel. It's funny that the to get to EPA standards we have to burn more fuel inefficiently to reduce NOx levels. Really is backwards if you asked me... but then again, what do I know...
I believe advancing timing can somewhat help with relieving us of excessive soot but it's always going to be there due to third injection happening so late. There is no way around it. I read that someone was able to stop the third event, but lost over 100hp in doing so.

there has to be enough intrest in this to get a programmer to bring the 3rd pulse back into the 2ond or eleminate the third and increase fuel in 2ond , this is killing fuel mileage if any one gets a chance to talk to bob or other rep.s ask them if they have anything in the works

That doesn't make sense. How would increasing fuel in the second shot and eliminating the third help? It's still the same amount of fuel being used.
A first gen truck weighs about 1500lbs less and has half the horsepower than a third gen truck. And it gets much better mileage. There is your answer. Nothing wrong with later models except that they are heavy and powerful. And I wouldn't want to change that at all.

not correct the third pulse is injected after the efficiency time of the cycle is over they had to do this to meet the new regs if you were to remove all of the things done on hpcr's for smog controll you could easilly see 40mpg , to get the mpg's up for 2012 i think you are going to see higher rail pressure , advanced timing egr elemination and elemination of third pulse and going to some other exhaust device maybe uretha or some type of electrostatic unit

When exactly does the third event occur? When the piston is still on the power stroke? Cylinder pressure would be quite high here or does it occur on the exhaust stroke?

40mpg in a 4 ton truck??? what world are you living in? A little VW diesel gets 45mpg... come on.
And it's urea not uretha...

Wow i feel much better after reading this thread because i thought i bought a lemon..I had less than 300 miles on the oil change and it was black, the truck has around 56000 miles on it. My old truck(99 cummins) had 130000 and i could go 2000 miles and the oil would still look golden with slight tinge of black. I am really glad there are some real oil experts here, i was scanning threads all night..After reading this thread it sounds like amsoil bypass is the way to go to catch the 7-10 micron particles, what is a reasonable service interval with this bypass system under normal driving conditions?(commuting and towing boat to lake during summer)...Is it normal to get a small puff of black smoke off of idle(punch pedal) at operating temperature? I dont notice much if any when on highway and puching the pedal tho. There are no mods to engine that i know of. thanks again (i still have my hair)
