In response to my pressure readings using the Wix filter before, I just changed the oil and got a Bosch Premium. The guage now varies when at a constant rpm, particularly highway speeds. From what I can tell the pressure readings seem to be maybe slightly lower on average. This is an auto-rx treatment, so I'm gonna try the Bosch after this treatment to get a more fair estimate. But I will say though once again that of all the filters I've used on the Jeep thus far (PureOne, Bosch Premium, K@N, and Wix) the Wix has generated the highest pressure readings by a slim margin and the K@N the lowest. I will let you know again after I finish this rx treatment.
