I have been running FRAM Ultra XG11665 filters for 20K mile FCIs with 4-5K mile OCIs using Rotella Gas Truck. The oil is typically down to around 2.x TBN when I change it and though I know that TBN is not linear, 5K is easy and all of the RGT was bought on clearance for $1-$2 per quart.
With that in mind, what concerns are there to run this filter for 20K miles? The Jeep community lost their minds over it despite the fact I have solid data behind my decision. One of the main reasons I do it is because in FCAs infinite wisdom (unlike MB) they designed the oil filter housing from plastic and crimped it onto an aluminum oil cooler which subsequently cracks and develops an oil leak. Though I am extra careful with the torque, the less times I loosen/tighten the better.
Those who know me remember that I did this with my 2010 FX4 after going 15-17K on an oil change and I had zero issues. Just curious as to whether there have been any recent experiences with FRAM Ultras where I should (re)consider my FCI. Note the twist in the filter is completely normal for FCA 3.6L Pentastar engines so that is not a concern.
TIA!
