I did not know that.ST2 is no longer a combo valve ecore. It’s a Fram EG with a black ADBV. A few of the line is like that now that Fram and Champ are under the same ownership. I actually miss the ecore design.
Never saw anything here about that, and have not looked at them in quite some time (last ST2 I bought was over a year ago and was still the old blue can with combo valve).
It will be quite a while till I need another ST2 sized filter, I have a TG2 and XG10575 in my stash for the truck, and I am going on 2 years right now on the Mobil 1 filter on it that I will be changing at some point in the near future.
