AMSOIL Series 3000 HDD 5W-30 at 2 year intervals, generally about 24,000 miles. Also have AMSOIL bypass filter. Change fullflow filter at 1 year, bypass at 2 year intervals. Doing this since 2007. Backed up with OA.
I know this will raise questions and eyebrows but it works for me. Got the CRD with 17K on the clock, now almost 99K. Will be doing the timing belt in a couple of weeks.
Ah-ha! Someone to verify that I saw Series 3000 5w
30 for the Liberty CRD --and someone with 24,000 miles on a single change to boot!

(i realize it likely has a lot more to do with the filter)
