Well since this started as an oversized filter thread WIX makes one for the Jeep the # is 51515 but its not recommended to run with synthetic if you are going to run synthetic I would stick with Amsoil oil and filter. Amsoil makes the best filter bunch of videos online how well its made, but I like to change my oil every 2500 miles or 2 months so its worthless to me. What everyone else is saying unless your in Canada or Alaska where its -10 everyday and night I would stick with the thicker 10w-30

 

Has anyone ever noticed their oil pressure drop after switching to the oversized filter?? I had the regular sized one on and would always be @ 51-52'sh (its just a hair over the 50 dash mark) and then when I switched it went back to the same point.. All is good right, well all the sudden im idling at a very slight incline and just happen stance I notice my oil pressure is @ 40?? Its not a big deal by any means but I just thought that was interesting and wanted to see if anyone else has seen this ever.
