Mineral , semi synthetic or fully synthetic?

I don't think Delo 400 can last until 10,000 kms OCI. We used it with BD28 and the mechanic says its "burnt" or has noticeably degraded lubricating properties based on what he felt from the dip stick. Current mileage is 8,5xx from oil change.

We are going to try Rimula R3X based on miko's post. Roughly 137/liter for a 20li/pail. Its 202/liter from a gallon pitcher at the shell station.

Mobil 1 Delvac MX is 245/li

CI-4+ na ung Delo 400, If it can't reach 10K how much more if you use Rimula R3X.
