As I said, exceptions are there, and I hope that your machine brings many more hundreds of thousands for you inshAllah, Mabrouk!
Essentially what I am saying is that diesel fuel sold in Pak causes the engines to emit oxides of sulphur, which are VERY BAD for the oil, and deadly for the catalytic-converter! And without a catalytic converter, no engine can comply with the Euro 2 standard.
Strangly, the oils that are sold in pakistan (for diesel) are meant to cope with diesel having not more than 0.25% sulphur (at-most) (find this out for yourself what fuel API Ch-4 CI-4 is meant for), but the govt. sells killer diesel with 1% sulphur content! What a shame and a mess!
