What are you fellows using for the engine and grease for the stuff needing it. Why not toss in what you use in the Transmission and t -case?
As for me with my AMC 258 i6 / 4.2l its NAPA 15-40 for the extra zinc, Lucas No2 Red and tacky, and Valvoline 75-90 for the Transmission and t case/axles too.🏴‍☠️
 
.30 over AMC 258 i6 / 4.2l gets royal purple 10-30 or 40 when I can find it and k&n filter Transmission and t case 75-90 weight all grease fittings (shackles u joints steering etc) gets a marine grade grease.

I find these older heavy 4 speeds (T-18 /19, NP435, SM420) shift better with non-gearoil lubricants. Tractor Supply Ford tractor Transmission fluid made my T-18 in the last Jeep actually shift. Was planning on putting the same in my NP435. I think the Tractor Supply stuff is like 50 weight motor oil. Transfer Case has no synchros so I don't think much about its fluid - just whatever gear oil.
 
My AMC 258 i6 / 4.2l I use Valvoline 5w30 and 50w oil in my T-176 and Dana 300 . Haven't any problems with stiff shifting in winter since I switched to 50w for the tranny
