These were fist fight level discussions 20 years ago. Mercon vs Mercon V got people banned.
I only use Motorcraft Mercon V because Mercon was discontinued. That was a rage bait discussion too of using other brands.
Motorcraft filter, new felpro gasket, you may or may not have an inline filter up by the radiator. Follow your lines.
Do not forget to check that the old pan filter's o ring comes off and doesn't stick in the valve body. Double stacking the o ring will have the filter be too low, then crack when tightening on pan, then you let trash through the crack.
