For your 2012 Volkswagen California 2.0 TDI diesel, I would recommend:
5W-30 fully synthetic LongLife diesel engine oil
This is the important specification to look for.
What to look for
Make sure the bottle explicitly states VW 507 00 approval.
This oil is suitable for the usual 2.0 TDI engines fitted to 2012 California models, including those with a diesel particulate filter (DPF).
Good choices include:
Castrol Edge 5W-30 LL
Mobil 1 ESP 5W-30
Shell Helix Ultra Professional AV-L 5W-30
Don't buy ordinary 5W-30 unless it specifically meets VW 507 00.
