Just a note about my switch to a WIX/NAPA filter for my Crown Vics:
I have 03 and 06 Ford Crown Vic Sports. The 03 w/130K miles has been run on MC 5W30 whereas the 06 w/11K miles has had nothing but MC 5W20. For the last 2 oil changes on both cars I tried the WIX then NAPA Gold filters. On BOTH cars, I started getting a serious engine rattle upon initial startup after maybe 2 hours of shutdown. OK when cold. The ONLY commonality here is the filter. The MC NEVER did this! I have already started back using the MC filter in the 03 and plan to switch back next week when I do the 06.
The MC FL820S is a superior filter.
