dark oil @ 300 miles

2011 ram 2500 cummins. 300 miles on it and when i went to check the oil, it was pretty dark. Now, since this is my first diesel, is the engine oil for the diesel normally darker than gasoline engine oil? Should i be worried that the oil is dark with only 300 miles on the odo?

Dark oil is normal for a diesel. This tells me the oil is doing its job by grabbing and suspending soot and crap. All is good dude.

It will eventually turn completely completely black and when you change the oil and run it for a few minutes it will be black to. This is normal for diesels.

Yeah stock it will be black as soon as you run the truck. Do the deletes and it will be so much cleaner.

word of advice dont get that oil on your skin it stains your skin black...lol oh and if you change your own oil have a bunch of rags handy cause it comes out quick...lol do the deletes like everyone has suggested and it will be a 100 times cleaner AND get better fuel mileage...

Yes, diesel is dirty by nature (suity). In fact, when it comes time to change it, it will look like you have graphite all over your hands.

I'v got the egr unpluggeed and the oil still gets black in no time. Do you have to do a full delete to keep the oil clean?

The only way to keep the oil clean after a change is to not start the engine.

Exactly..every other diesel I've owned had "clean" oil for at least 4000 miles.
