I’ve been researching the STP XL filters for a while now. I’ve been impressedLooks good
And yeah, that one is exciting because Pentastars are known for twisting the pleats, even in a wire-backed Wix XP! So the fact that any Pentastar filter comes out with the pleats straight *is* notable
I've heard that as well but oddly enough I have never witnessed it myself on any of my 3.6's.Looks good

I looked at them too at AutoZone. It was a toss up between the STP XL (made in China) and the MircoGard Select (made in Vietnam).
Ran Mopar, Fram XG, and Mobil 1 … only M1 was not twistedLooks good

I’m pretty much with you there, it’s a toss up between the two. I considered the TG Fram as well but these two just seemed better quality. There isn’t an Orielly’s near me so the choice was made for me
Good Morning MuzzleFlash40,
Hi GMBoy,
The usage of the vehicle in this example is mostly highway with a 44 mile commute to and from (88 miles a day) of this about 10 miles are city. I would say it is a solid 60/40 (highway/city) use of the vehicle after throwing in weekend use etc. I have used WIX, STP, FRAM and a CHAMP all with the same outcome in 2 different P-Stars (2014 Grand Cherokee and the 2020 Gladiator) as the photos show. I never had one with bad wavy pleats in my personal vehicles but I have seen it on cars we service. It is odd and I would love to know the reasons as well.
That a great point. I can tell you that in my case my vehicles see plenty of WOT lol so doesn't seem to make a difference. I would think the filters are designed to handle higher pressures then the engine can make as well as the pressures a cold start in zero degree weather as well.
Any time there is higher oil flow volume (which there would be at 65 psi vs 29 psi of oil pressure due to the PD pump), then there is going to be higher dP and therefore more stress across the media. Filters see more higher and longer dP episodes in cold weather of course. As always, the engine shouldn't be revved high until the oil warms up ... that practice alone will help keep the high extended dP episodes down.
The filters need to be designed and made to be able to take the max dP across the filter without causing damage to the media or center tube (tube collapse), which is suppose to be limited by the filter's bypass valve. The "burst pressure" of the filter can (and the base gasket sealing of course) needs to be able to take the max oil pressure supplied by the pump. If there is no oil flow going through the filter, there is no dP across the filter ... regardless of how pressurized the filter can is. dP across the filter is a function of the filter's flow resistance factor, the oil viscosity and the oil flow volume going through the filter. If the can was at 200 PSI and the flow was a trickle, the dP acorss the filter would essentially be zero.
