Nate,

The LO 9-2320-244-12 specifies 90 weight. I believe when I was in the army it was called "GO-90". Not something special. It specifies 80 weight for the winter...

Nate, use pure synthetic straight 50 weight in the trans same as semi trucks use ans 85w140 pure synthetic in the t-case. Been usseing this for 25 yrs 0 problems. Also its a lifetime oil change,once in you,ll never have to change it again unless you get water in the boxes. I use castrol syn-gear lube.
