Bought my Jeep with 112,000 miles on it. It was 2 years old with recorded
oil changes every 3,000 miles. I use Wal-Mart filters and oil. Change oil
every 5,000-7,000 miles. The first engine went to 255,000 miles. Lost the
cam. Second engine (used) had 55,000 miles when installed. The car now has
440,000 miles on it. Same Wal-Mart filters and oil. Does not leak a drop of
oil, excellent oil pressure. I did read a study that their filters perform
very well as well as their oil. (for modern cars)
