Don't know what merc you're talking about, or what super duty is, but I'll guess.

A Merc V6 LU will do best with Mercury high performance gear lube in it. In a pinch you can use a full synthetic 90W automotive gear lube, but ordinary GL5 is not sufficient either in film strength or in water suspension.

hope it helps
