Mine looks like dirty black oil.Just wanted to say thank you for the info. in your third paragraph. My wife's just been driving the 80 locally. Today, I decided to check the catch can and a saw a little milkshake at the bottom of the can (less than 1/8")... nearly s*** my pants... pulled the main oil cap... all good. Thank heavens.
Doing the job just as it should.
No milkshake
