Hello,

That color of oil typically indicates a blow head gasket which allows coolant to mix with oil. That also creates white smoke out of the tailpipe.

Keep in mind that to have a leaking head gasket the engine does not have to overheat. It can leak due to wear and tear.

Here is a helpful guide on how to check for blown head gasket:

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
