I usually use motorcraft filter FL820S on my mustang gt for about a years now, and I have lifter tick every cold start, I chose motorcraft filter because its OEM and it look more bulky on the inside then any other brands. but since I bought a oil special on AAP 5qt castrol gtx high miles with pureone filter for 20 buck, my car now have no aor very short lift tick on cold start. I think I will stick with pureone filter from now, I just wonder how long pureone filter last ? thanks
