G80 LOCKER

[sirhuntalot1]

WAS GIVEN ADDITIVE TO PUT IN G80 AND ALREADY CHANGED IT OUT ON 4X4.

AFTER RECEIVING INFO IN ANOTHER SECTION OF THIS FORUM BY 2 OTHER MEMBERS I WOULD LIKE TO GET SOME BACKUP ON THIS. GM SHOP SAYS NO PROBLEM HAVING THE ADDITIVE IN THE G80. HAVE PULLED 6300LB TRAILER 710 MILES WITH NO PROBLEMS. AM I GOING TO BE OK WITH THIS? USED IT WITH MOBIL 1 SYNTHETIC GEAR OIL. TIRED OF GETTING 50 DIFFERENT OPINIONS THANKS GUYS FOR ALL THE HELP

So, the 51st opinion is going to make a difference? GM says the posi additive is not needed in that axle. Will it hurt? No, probably not, but I don't have the facts to back that up.

 

I'll try finding the document from GM that states not to use it.
