Diesel quality and availability
This is very complicated subject. I have new Mercedes euro6 engin. After travel to Algeria, Irak (using diesel there) and Europe, made 35 000km. After that I got info:exhaust gas treatment end failure. I made with this problem about 7 000km but finally it was replaced with new parts (2 parts on guarantie). Ussualy mechanics says that problem is not with diesel quality but with ad blue quality or lack thereof.
Next month I start 60 days trip to Algeria and some other african countries. I have 2 solutions. First is take 100 liters of fresh, good ad blue from Europe. Second is device called Ad blue emulator. You can install it and engine "forgott" ad blue sensor. I have it but not instaled. I try to check my first idea and look how it will work. I'm not worry about hypothetical problems as I have new sensors.
As I said before, this is complicated, some solutions are illegal.
The best is driving old cars with no ad blue, but we also like new ones (and we have problems).
