What oil filter do you run and why
I'm not sure. I found while reading the link posted earlier in the thread.

"This filter was interesting, but unfortunately only in bad ways. I also found this filter at Murray's Auto Parts, but left it there when I looked at the backplate. I decided to get one from the dealership instead, but it was exactly the same. Cutting it open confirmed it: this filter is a Fram Extra Guard (the radioactive orange one). It's definitely the cheapest Fram design with the infamous anti-drainback valve sealing against the cardboard cartridge end caps, and the plastic bypass valve. It's always easy to identify a Fram Extra Guard by the cheap looking, thin backplate with many small holes for the oil inlet. How Chrysler can call this cheap filter a "Severe Duty" filter is beyond me, but it is stamped right on the can. Even Fram makes better filters than this (Tough Guard), but they probably cost too close to the Mopar $6.50 oil filter price for a decent price mark-up. Fram does not list a part number for this filter in the Tough Guard version."
