Can't go wrong with Castrol oil and C4 is recommended for diesels with dpf.
I was struggling to get C4 oil for my 1.6 dpf qashqai as my local auto factor store kept saying c3 Renault/Nissan oil was good enough but just clogged up the dpf faster with soot. This oil has made the car run longer without clogging up the dpf. If your diesel with a dpf recommends C4 oil... Use it.
