Wow. Autocorrect really screwed that up...lol. Is the additive necessary with the s-trac? Pretty sure its not, but wanted to double check. My paperwork from MWC walked away. What fluid recommended for break in?

No additive necessary for the S-Trac diff unit. Use 80/90 non-synthetic oil, will require just over 3 quarts.

Be sure to follow the break-in procedure when you get ready to go.
