Fram is certainly going to keep the oil clean. It’s a little more restrictive than other filters but that’s probably fine
The Ultra is not any more restrictive than the others. This test data if from an official ISO 4548-12 test procedure.
Would you all like to see ISO 4548-12 Oil Filter Lab Testing Comparison, Efficiency & Capacity, Pressure vs Flow, Bubble Point, and Burst?
I have this as a “watched” thread, so if you do happen to start a new one, could you put a note or link in this one to direct followers to the new thread? Thanks!! Yes, no problem I can do that.
