Did the first oil change and was glad I had a 4 gallon bucket. While the oil was draining it seemed to be thin as water. The engine was warmed up but the oil seemed thinner than the 10-40 I drain out of the old truck.
I was expecting the drained oil to be black, like it is when I change the oil in the tractor. But this oil had a chicken-**** brown/green color to it. Is that what color ya'll see in your old oil?



2004 F-250 6.0

 

It ought to be black. Send a sample off to Blackstone lbs for a test. How much total did you get out?

 

The factory fill oil is 10W30 (thus the thin-ness) and has the leak-detecting dye in it (thus the green-ness). Yeah, first time I saw it on a 7.3 truck I thought "oh no, antifreeze in my oil!" You'll note it is more flourescent green out in the sunlight (that has some UV light in it) as opposed to in the garage under artifical light.

Thank you very much Frobozz, that makes total sense. And it was more obvious in the sunlight.
That 4 gallon bucket was almost full but it could have held another quart. The bucket had just enough clearance to fit under the truck. I might have to borrow another one of those buckets from the work place.
Thanks

 

Send some back.......it would be cool to see what they (Blackstone) would say

 

People have sent off their breakin oil before - if you plan to do rigorous oil analysis, it's the best way to map the whole history. They'll tell you it's 10W30, that it has dye in it, and probably that it has a high concentration of bearing and ring related metals, but you should expect those to calm down with subsequent changes.

I sent my break-in oil off for analysis. The results on my Club FTE WEB site. Basically the oil was black. My results are skewed I’m sure as I had just changed the oil in my old 150,000 mile Jeep and didn’t get the drain pan completely empty when I started th eoil change on my truck. Also I didn’t get a mid stream sample. A friend who had just bought an 04 came over to watch and I got side tracked. I just dipped some out and figured worse case it would show really bad. Blackstone said mine was normal for a first change so I am comfortable. I would definitely send in any strange colored oil unless you know for sure the dealer added dye to it.

 

Saxon, just wondering what is the build date on your engine?

 

How did you here about the dye? Did FMC put it in all 6.0? I am asking because my oil looked the same and this being my first diesel thought that is how the oil suppost to look.

 

I dunno - someone asked International once and that was the answer they got. It's been the same in all 3 of my Powerstrokes - factory fill flouresces green in the sunlight. It also did it when I changed the oil after they were looking for my bellhousing leak source. The oil you buy in the store won't look like that when it comes out again.

If it was antifreeze in your oil it would be a milky white color.

 

Well sure, it would look like that if the engine had been run with antifreeze leaked into the oil. This stuff looks at first glance like antifreeze mixed with oil in their natural states. Clearly it isn't, it's just leak detecting dye, but that's still going to be an obvious first thought when you drag that pan out from under there and into the sunlight.

Mine looked the same after first oil change. I sent in a sample and everything was normal for a break in oil, although the silicone level was very high. They noted that this is normal for a new engine; something about the castings and assembly lube. I am due for my next change soon, and will sample again just for peace of mind.
