As the wise old Owl would say "Search is your friend". Use the Advanced Search function. The KJ CRD Oil topic has been discussed a few times, and it is also covered over on LOST (

My 2 cents: I am using Penrite Diesel 5 HPR and it gets changed every 5000km. I started my vehicle out on Mobil 1 0W40 but that stuff is too expensive and is not CI rated. The Penrite stuff is cheaper (about $76 for 10 litres), and is a semi-synthetic. Watch what your dealer service guys put in as it varies depending upon their supplier arrangments.
