residue in oil cap

I changed my oil today and found a green residue in my oil cap. Is it just oxide oil? The oil I had removed looked to be normal.

was the oil level high? What did that cap smell like coolant? Do you have gold motorcraft coolant or are you running green coolant? What kind of oil?

never seen that before, might want to pull an oil sample next time if it's there and send it in if your worried about it. almost looks like oil dye.

Did they put Flourescent Dye in your oil at some time? There is no way thats coolant gold or yellow, coolant isnt even that bright color, and your oil would look like chocolate milk if there was that much coolant all the way up the filler neck.

Youd be surprised ive seen a cap look just like that before, it was because of an aftermarket oil cooler on a delorean! Usually when its coolant or any moisture it will be foamy your definitly correct. I must not have been thinking on my previous post, but its definitly oil dye, thats the right flourecent dye color.
