Pretty much everywhere I've read consistent UOAs online that it maintains its TBN at 10,000miles (15~16k kms) and since its also the most expensive diesel oil out there it just feels wasteful to change it out early since I racked up 10,000kms in under 7 months.
Yes pwede if not so polluted or dusty or the driving is not rated as severe. If it is, best to keep it at 10,000kms between OCI.
