So I just crawled underneath and took a peek. I didn't see a plug with a blue dot on it since mine is a 4.8i so likely don't have that blue dot. But I am pretty sure it's the drain plug even without the blue dot.

What does the front differential oil color? This one is brownish clear like the synthetic. It sort of smells like engine oil as well.

Isn't the power steering oil color red?

I checked the oil dip stick on my 4.8i and it's a tad above min. Need to top it off.
