I don't have previous filters unfortunately. I'm not worried about the black, be it carbon or RTV left overs. The filter was doing its job, that's all I cared about.
Motor has 135k, 2012 Cruze Eco. Used these filters exclusively, and will until my stash runs out.
I wanted to use an XG10246 for the longest time, but only one store in my area carries it and charges $15 each. I got the CH10246 on clearance for $1.40 each and picked up 20. I'm about half way through them. From my research back in the day (when I bought the vehicle and these filters), these Fram's actually were Hengst filters based on the patent numbers being the same, and Fram probably contracted them until they started making their own. I have no proof of that, but I do know the markings have changed.
