There is only one oil available in Australia that is approved to MS11106 Chrysler spec and that is Mobil 1 ESP Formula 5W30.
I supply this oil to my dealer at service time to ensure our WK2 CRD doesn't get filled with their "one oil fits all".
I also run Wesfil air, cabin and fuel filters (readily and competitively available from
http://www.eziautoparts.com.au ) - I get the dealer to fit a genuine oil filter at service.
With many thanks to Jay.mak from over on the Jeepgarage forum, i've extracted info from a post in one of the threads relating to oil over there.
