Yesterday I installed a Yukon Duragrip in my '04 Yukon with the 8.6" 10 bolt. I used approximately 2.5Qt of 80/90wt gear oil and what I guessed to be 2oz (about half of a 4oz bottle.) I was surprised that the diff was quiet the first drive while turning in a circle at full lock both directions. I wonder if i could have used half as much FM?
 
I wouldn't worry about it, it sounds like you "guessed" wisely

Diff is brand new and I could smell the fm in the clutches already prior to installation.

Gear oil is non lsd dino O'rielys house brand.

I do offroading where wheel spin is common.
