Has anyone ever seen M66 separate like this before?

I threw out almost a half gallon about a month ago and never thought to check the dispenser bottle. Well, yesterday I saw the dispenser bottle when I was in my cabinet getting out some supplies to clean up our Yukon and sure enough it was the same. So, I thought I would see what some of you thought.
I believe the M66 was somewhere between 18 and 24 months old from the time I purchased it.
Not that I would think so but, could age be a factor, especially if it was already pretty old when I purchased it? I know the most common questions when something goes bad is "did it freeze or get hot" And the answer is no to both.
Not a big deal here, just wanted some thoughts........
By the way, what you see in the picture is after I shook the living daylights out of that bottle several times!
