what fluid in a dana 60 locker ?

[Fast68Chevy]

what fluid would or do you use in a dana 60 locker unit axle ? whats good and whats not ? i suppose just normal GM limited slip additive mixed in with normal 80/90w oil ?
as stated on the cover tag ? ? mix ratio ?
what about if using synthetic fluid ?
wanna see what others know regarding this

thanks

Dont waste your money on the friction modifier additive. It doesnt do anything with the locker unit. It only works with limited slip type clutched units. 80/90 or heavier grade or synthetic will work. Synthetic tends to find any opportunity to leak though so its your choice..

I just reread your post.

"as stated on the cover tag ?"

Are you sure you have a detroit locker and not a clutched limited slip? Lockers are a different beast you know.
