Engine = 15W-40
Powersteering = Powersteeing fluid or ATF
Brake Fluid = DOT-3
Transmission = Dexron3/Mercon
Transfer Case = Dexron3/Mercon
Differential = 75W-90
Coolant = 50/50 with anti-cavitation additive.

No additives clean oil is better. I use synthetics myself have had great luck with the stuff.
