CRD Diesel Engine Oil
Search is yr friend.
See KJ thread 73936 "Best Oil for a CRD"
also Grand Cherokee thread 73310 "Engine Oil Viscosity 3.0L Diesel Engine"
I use Mobil 1 ESP 5W-30, and perform oil + filter changes every 5000. (I do it before the dealership gets her for the 10K interval servicings)
I know it appears overkill, afterall its a fully synthetic C3 compliant drop,
and i've only ever been able to buy it in 20L drums ($255)...
and we dont even have a Particulate Filter to poison,
but we do do some serious towing (ref previously posted photo) and a fair % of alpine wandering. Its the price i pay for some peace of mind!
