I'm going to respectfully disagree slightly here. In this situation, I'd be interested to know if Na (Sodium) was also elevated.

It is most likely that coolant is the cause of the milky oil. But there are avenues for it to be saltwater. For the $20 that and almost no time that an oil analysis costs, I'd want to cross those definitively off the list.

But, I agree, I'd have gotten that milky oil out of there right away. I'd take that oil sample as I was draining it out! (Before refiling it and turning over a bunch, and repeating.)
