Self oil change what's your oil looking like??

[StaffyBull]

For those of you that have changed your own oil what's it looking like? Is there much extra soot, fluid or fuel in it?

I dropped my factory oil at 3k miles and it was dark, definately from a diesel, but not as bad as I have seen many times before on other equipment. It cleaned off my hands easy, not like india ink I have seen before.

All the smog and soot equipment on these trucks treat the exhaust so you could expect the lubricating oil to remain about like other diesels. I expect mine will get much dirtier as the miles pile up.

Changed mine at a hair under 3k. BLACK AS MIDNIGHT. I'm super anal so I changed it again last week still black as anything. Is this due to the EGR? I've never seen oil so black. Then again this is my first diesel.

Diesels make it dark, thats for sure. You will get used to it.

I think that the emissions equipment makes the oil get dirtier faster. I believe that this is why they developed the CJ-4 oil. On my 7.3 the oil is just as black after a change as it was before. But that is due to the HPOP resivour.
But that oil being black that soon bothers me a little.

The emissions stuff does not help with the oil staying clean.

Anyone measure the amount of oil/fluid after a change? Im wondering how much fluid is getting put back into the oil. I have seen a thread for got if it was the Dodge 6.7 or the 6.4 or both about extra fuel mixing in the oil cause of the emissions crap. So Im wondering if the urea will make its way into the oil system and what that could do.

[Oilburnr]

Unless I am mistaken the Urea is injected into the DOC downstream of the motor so there would not be any risk of Urea contamination in the oil. That is the route GM took with the 11 duramax, they added a 9th fuel injector just upstream of the DPF eliminating the risk of diesel contamination in the oil.

[smokersteve]

It is dark because of the immense emissions control components

Staffybull,

Urea is injected downstream from the motor, not in the motor. So there shouldnt be any worries about urea contamination with the oil.

Now, fuel is a different story because of the in cylinder regen process. So far there hasnt been any reports of fuel contamination occurring with the 6.7 and hopefully it will stay that way.

I changed my oil for the first time at 5K. Of course it was very black - but visual indication of being black does little to determine oil quality - The truck's oil quality monitor indicated the oil was fine.

I could fit a 4 gallon bucket under my truck (all kinds of room) but first I measured 13 quarts of water out and marked the bucket so I could determine how much oil I was removing.

When I drained the oil I dumped the filter assembly right into the bucket (I thought that was the easiest way not to make a mess). My indication was a hair over 13 quarts, which makes sense as the filter component volume (metal skin, filter fabric, baffles, etc) is minimal compared to the oil's volume. So I believe there was minimal (if any) fuel oil dilution.
