You need to have 'low saps' (low ash) oil, especially with he DPF, it reduces the deposits on the DPF (that will block it!), normal oil will give you DPF problems. Should be ok if it is approved alfa, fiat or GM ( for their CDTi).
Using Mobile 1 New life myself (one of the quality oils that was on offer).
I know mine is only a1.9,(one less cylinder), but only regens every 1,200km. 300km sounds far too much, might be worth getting it a proper regen with some wurth DPF cleaner in, but you may have other issues.
