Once again another good ECORE cut open for me. No endcaps were unglued, everything was on tight where it was supposed to be. Time on filter was 3k miles on Chevron Supreme 5w30 conventional. Reason I only did 3k is some heavy towing. I replaced it with a Champ non-ecore AcDelco Pf52 I had sitting in the garage and some Valvoline w/b 5w30.
