Good question. I was looking into this myself wrt modern ULSD vehicles.
Algeria was the last place in the world to go unleaded and according to this it's diesel is <2000ppm. (ULSD is <10ppm, afaik).
Is it just a matter of the DPF clogging up and needing regular replacement, if possible, or engine management issues? I'm not sure if additives can remove particles, can they?
I would have throught the manufacturer will have the answer but I'm sure there is no ULSD down south. As it is I do recall the south got the rougher end of the fuel stick, but that was years ago. I will know a bit more in January.

As for range, 1000km is minimum - more for piste exploring.
Few places are more than 400km apart in a direct line (road/piste).

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).

Thanks Chris, am not sure to be honest regarding the DPF but INEOS are recommending additives and replacing the fuel filter more regularly. Quote 'owners need to ensure that they purchase diesel that meets the minimum requirement etc'. The Grenadier uses the BMW B58 diesel which is nearly 25 years old and is in tons of 520D and X5s.

Thanks for the intel on the range, I am getting 68.5L of additional capacity added with tanks but may need to add more
