First oil change on my wife's new-to-her Suburban. Catch can was surprisingly full and had crap that had wet almost peanut butter like consistency at the bottom. The can is much smaller than the Elite Engineering can I had in the old one, so I need to remember to check it a bit more often. All that crap has collected in about 3500 miles.
Also installed a Fumoto valve to make future oil changes a breeze.
