Those that has all those diesel emission reducing mechanisms like DPFs, SCR NOx and etc.. Alam ko meron nang DPFs yung recent diesels but I'm not sure about the others. Maybe the European diesels but I'm sure they've adapted it to our diesel quality here. I'm not even sure if all gas stations use Euro IV diesel fuel at all, with < 50ppm of sulfur.
