Diff oil

About to re-install the diff so did a search for what type of lube would be best for a LS. Dana 44 (kirkham) Morris replied to a thread that he found Mobile 1 75/140 was the best and reduced the diff temp . He didn't mention if the LS modifier was required with that oil. Anyone have any experience/thoughts on the subject?

I copied this advice from the Kirkham website:

Kirkham differential oil:

The oil that should be used is Mobil 1 75w140. This is the best oil we have tested and reduced our temp by 40-60*degrees. Way better then all of the other products.
