Just to be fair the stock FL1A was used even on 460s. It has plenty of capacity for a 2.9

I’m really surprised that with all the research and “I’m stoned, let’s try this” ideas you have, you haven’t bought or pieced together a bypass oil filtration system.FL1A for me, motorcraft only.
I've run some of the more exotic ones like the Bosch extended life... Not worth the extra scratch imo.
Bronco graveyard sells a magtech filter adapter. Apparently filters out iron fines. One is going on mine after rebuild just to catch magnetic break-in debris, but that's about it.
If you're looking for ways to extend your oil life, oil cooler helps greatly. But, they too can develop not fun issues.

No complaints about VR1, just don't know that I can source it locally. Guess I can order it online.
Advance Auto just started carrying it not too long ago. Might want to check with them, seem to be reasonably well priced as well. If nothing else, there's always Amazon
So, no joke I saw that on the Explorer forums at one point. I did briefly consider it.
