The FSM recommends 5W-30 or 10W-30. I run 5W-30 in the winter and 10W-40 in the summer. I also run a Mobil M1-301 (or equvilent) oil filter. It's a little bigger than the stock filter and holds and extra 1/2 quart of oil.

If it's an AW4 (auto) tranny, it takes DextronIII/Mercron. Change the filter there too.

In the diffs, I run a synthetic 75W-140, but I think the FSM calls for 80W-90.

I would definatley flush and change the coolant, hoses and thermostat. Also tune it up - plugs, wires, cap, rotor, O2 sensors and air filter.

Clean the throttle body as well. While you have it off, check and clean the IAC.

Give the brakes a once over and replace pads/shoes/rotors/drums as necessary.

Grease all the zerks too...
