Jeep Engine Oil Viscosity
This was taken from pages 82 and 83 of the 1989 Chrysler/Jeep owners manual.
Selecting Engine Oil Viscosity
When changing or adding engine oil select the proper grade by using the chart on the following page. Select the grade that corresponds to the ambient temperature range you expect to encounter before your next oil change.
30*F to 100*F+ 20W-40 or 20W-50
0*F to 100*F+ 10W-30 or 10W-40
-20*F to 60*F 5W-30

I know you like quoting that page a lot but you do know that engine oil has changed in the last 24 years, eh? lol
My standard answer is "run whatever makes your Jeep happy". Just run bloody oil

Filters are the big buggaboo with our's being mounted upside down. Have to have a filter that has a good anti-drainback valve. No cheap crap.
