Transfer case oil?

[Lax]

I know this is a simple question which usually turns into a long debate but can anyone suggest an oil for my M35A1 transfer case? I am going to use non-detergent 30W for the tranny but would like some thoughts for the transfer case. The truck sits for long periods. Thanks.

You might want to reconsider using the 30W oil in the transmission. Just use a good 80/90W oil in the transfer-case and transmission. At least use a 50W oil in the transmission.
Big Dumb Truck posted today about using 30W in his transmission. You might want to read it.
