I'm partial to Wix filters, but recently I have been having check valve/oil drain back issues with them. This is not only on my XJ bit on my JK, and KK. The JK I switched to a Fram Tough Guard and the knocking/oil starvation at start up is gone, I can't remember what's in the Liberty since the wife took it to Walmart last oil change.... I would assume a Fram. I just changed the oil on my XJ and put a Wix filter in it and the oil starvation and knocking at start up is horrible!!! It reads 0 oil pressure for a good 5sec after start up. I was about to go buy an other Fram but wanted to hear what you guys run first.
