4wd trip to Mongolia - how's the diesel these days?
 

I am thinking of doing a 4wd trip to Mongolia in two years time and would appreciate any info about the current quality of diesel in Kazakhstan and Mongolia and any problems folk have had as a result. Online has various views and facts about the high sulphur levels but also about the green targets etc.

I think a Euro 5 or 6 engine would probably suffer so a Euro 4 would be a better bet for higher sulphur.

Anyone been recently or got any decent up to date information? Obviously things can change in two years but probably not that much, especially out in the sticks. I'm not going to buy a simple 30 year old Landcruiser that gets round most possible fuel issues but introduces many others, too old and whatever I get has to be my daily vehicle here so the last of the Euro 4's (2010) seems a good compromise, most likely Hilux or L200.
