I've owned 16 Pintos since 1972, and all up to this day, used over the counter major brands of oil. (Wall Mart oil too). I have NEVER lost even one cam in this time. In 1974/75 the Ford 2300 cams were junk if you ran the oil until it turned to tar. I've always changed mine at 3000 miles. On high mile car I would add STP. I found when I was just out of school to always try to find out what kind of oil had been used in the car before and keep on using it. 2300 Cams are made with a profile very much like a roller cam and as such wear like a roller cam. Keep the oil clean and NO day glow orange Fram filters and you'll be just fine. This post is just what I do. Use your brain and all will be ok.
