Yes, I also get uneven filling of catch cans. I do 5000 KM OCI. I empty catch cans @2500 KM (1600 miles) and then @ oil change.
How old is your car/mileage? My Xterra was getting milky catched oil. It was 300k KM's on engine. My 370 is younger, and is not making milk. Perhaps age and wear also increase water entrapment.
