This was on a 2007 Buick Lucerne (3800 Series III) for 5,000 miles put on in about 10 months. Unknown bulk 5W-30 oil. Was not used during the winter. Looked surprisingly good for an ecore. The end caps did not come off easily and the pleat spacing was decent. Still full of oil indicating a working ADBV, which was indeed still soft and pliable. It was really on there tight and hard to remove from the endcap/center hole. I would happily use one of these again after seeing this.

Nice! Thanks for the c&p. Makes me feel comfortable running a pf48e on our Yukon once my stash of Napa Golds are used up.
 
Looks fine. One thing of note, as this used on GM with block bypass, no combo valve used, just adbv. The ACDelco ecore for newer GM with filter integral bypass, has no combo either. They use a dome end poppet type bypass.

Thanks for c&p.
 
Looks identical to the Supertech ST3387A I've used on my Chevy truck just without the AC Delco sticker. The ecore filters have looked good.
