7.3 Clean Oil

[partsguy84823]

First off, I want to apologize for all of my "Is this normal" questions...

Now, on to my question. I have a 2003 7.3 with 135k on it. I changed the oil when I bought the truck, about 1,000 miles ago. Last night I checked the level, and it was good, but the oil looked as clean as the day I changed it. Everyone always talks about how a diesel will turn the oil black almost right after it is changed, but that isn't happening.

Also, If I'm not losing any coolant, and if I'm not seeing oil in the degas bottle, and I'm not 'making' oil, is it safe to assume I'm not getting coolant in the oil? The reason I ask, is the oil has a very slight green tint to it. It doesn't smell like coolant at all, so I wondered if it was just normal. I didnt study the oil color when i poured the new stuff in. It is Motorcraft 15-40.

So is it a problem tha my oil is clean?

That's a good thong if it's stayin clean mine will stay clean for about 1000 miles then starts to turn black as far as the coolant and oil thing I'm not sure I would think as long as the levels in the oil and the degas bottle stay the seem your safe. There might be a way to test for it but I don't know of any.

Blackstone Labs get an oil analysis. about $25 and will tell you a lot about the trucks condition. ive never noticed green tint, and only see the oil when i change it, its always black. where in KS are you?

My old man is anal about his oil changes. He uses 10W30 dino oil and changes every 3k regardless. He will let it drain out for HOURS to make sure every drop is out before putting the plug in and refilling. Oil comes out just slightly darker than new after 3k.
He's been doing that since he bought it new and it's now over 150k. The couple times he has had it changed somewhere, he's pissed the next time cause it takes him a change to get his oil "clean" again.

Funny... He is missing about 1.5Q left in the high pressure oil system even
being that anal. Drain it, change the filter and fill it back up. You may miss
a cup of oil that didnt drain out..
