Coolant in oil

[nbo10]

Hi All,
I have a 2020 with 30k miles on it. Changed the oil this morning and while watching the old oil drain out I noticed a small, but significant amount of brownish stuff coming out, along with the oil. Can it be anything other than coolant? The truck has driven differently over the last two weeks. The engine has been more sluggish.

I’ll make a service appointment on Monday, but just looking for thoughts on what it might be.

Take a sample and send it to blackstone. They can tell you if there's coolant in it, or really bad levels of metals. It won't be as good as pulling mid stream, but it's better than not knowing anything.

How much Should I drive the truck for a bit before sending in a sample? Right now it’s all oil because of the change. Thanks

If you have the old oil, I'd take a sample from that just in case. they are small only about 3 oz, or less than 100ml, less than 1/2 a cup.
