Fram TG16 - 2000 miles on my Jeep 4.0L in my Wrangler. I replaced the timing chain, sprockets, and cover gaskets 2000 miles ago, and wanted to do a short OCI to get out any junk that got inside the engine while I did this work. The filter looks good, which is kind of expected for such a short run. Not much debris in the pleats, there is a little in the can, I had a magnet on the outside. I dented the filter pretty good removing it, it wasn't real tight but it is hard to get a wrench on it since I mounted a coolant filter right above the oil filter. I used Maxlife 10w30 with this OCI, and a Fram XG16 and Maxlife Syn 5w30 went back in.
