Red Line Diff oil w/ and w/o

[j.o.y.ride]

Redline has 75W90 without the limited slip additives and 75W85 with it. Given I currently just have an open diff with no traction device of any sort, presuming the 75W90 is the one to go with.

Thoughts?

My thoughts.. you answered the question in your post.. For more info read the owners' manual.

Unless you have a clutch-type limited slip, use lube without the additive, as it has better lubricity.
