This was what I pulled out of the catch can after 10 days of driving to work and back, a few ounces of crap haha!
Definitely trapped some water along with the oil as it is brown instead of the usual black.

Mind you I only live about 15 mins away which may not heat the oil hot enough and it has been raining recently so the humidity is up. The catch can usually traps only oil.

I cleaned it all out and will re-check at the end of next month to see the results
