that link you posted was an interesting read.
however, a few items to point out
1, they suggest RACE OIL for engines making 100+ whp per cylinder (not the case here.)
2, GL 4 is now obsolete. mobil 1 is GL 5, now.

10W-30 Synthetic Oil | Mobil 1™ 10W-30
but i agree that more zinc is better protection. im going to look further into this myself |
GL-4 is what should be used in the manual trans. GL5 is meant for diggs and transfer cases. The friction modifiers in GL5 are too harsh and do more harm than good to brass syncros.
