I have a 2015 Yukon, 5.3, I installed a catch can and it fills up rather quick, about 1oz every 100 miles, that’s a lot of oil it would just burn if I didn’t have this installed. It that normal for these? The oil in it smells and looks just like that, oil, no hint of other contamination like water vapor. I’ve just been pouring it back into the oil. I will mention I have DoD turned OFF in my tune.
