Recomended Gear oil for Detroit and ECTED

I got both of these used and am getting ready to have them installed as well as 4.88s and 30spline shafts. What is the recomended gear oil for these lockers/TED's? I know the Detroit uses some type of aditive but I am not sure wht.

no the detroit doesn't use additives. the clutch operated LSD's do. I don't use anything special on mine so this will be interesting.

I run a TrueTrac in the rear with synthetic gear oil. I am installing an ECTED in a HP 30. Auburn states not to run synthetic lube with the ECTED. They specify 80W90 hypoid gear oil and a friction additive they included with the locker.

Auburn Part Number: 504102

Auburn states use of any other lubricants or additives may cause differential clutch chatter.

Cool I'll have to make sure mine came with the additive. I didn't see it but it may be in a small pack or something.

Should I use 75-140 syn for the Detroit?

I have been running Coastal 80W-90 in my 9" with a detroit for a couple years now without any problems. I haven't used any additive with it either since it is not required.

That is what I am running in mine. Also the book that came with the ECTED
states that Ford or GM friction modifier can also be used.
