Is this oil in my coolant degas reservoir? (pic)

I recently bought the truck and when I looked into the degas this is what I saw. I cant tell if it's just discoloration or if I have a big problem on my hands. Thanks guys.

I wouldn't panic yet. Any other symptoms? You said you just bought the truck so its possible the previous owner used a coolant with a different color. Its also possible that's rusty water mixed in with the coolant. Is there a separation in the degas bottle? Meaning are you seeing a layer of oil and a layer of coolant?

The majority of the floating discoloration is at the surface of the fluid but there are a couple pieces of different looking substance floating around deeper in the coolant

first thing to do is flush the cooling system and refile with a quality coolant. (not ford gold)

Found out it wasn't oil. Coolant was clean as can be but I still replaced it with CAT ELC. Turns out it was just dried crap on the inside of the bottle from the gold coolant.

I was just about to say that it looked like bad G-05 to me. Good thing you got it out of there. I especially liked the buildup on the square piece that's at about 3 o'clock.
