I bought Margalla 1 week back, I was thinking It has very good CNG average but It is hardly doing 115km in Rs410 55kg cylinder. And also I have found the Petrol Milaege very bad. So please tell me what should be its Petrol and CNG average in city. Engine is also in very good condition, Good pick and every thing. So plz help me, Tell me some profeesinal place in Islamabad where I can set the CNG/Petrol of Margalla to good efficiency. Thankxx
