The Purolator L24651 and Motorcraft FL-820S filters are not 5000 mile / 6 months whichever comes first oil filters. I have torn two FL-820S filters on Ford's service schedule.
The filter failed. If the filter is filled to capacity, the bypass should open. The media should not tear.
I have moved off these two part numbers.
The following cross references worked for me through 6000 miles and 6 months using 5W30:
WIX 51372, PF1250, Champ PH820 and Fram TG2.
Yes, I know two of these are eCores. While their efficiency is low, they do work without tearing.
