just got my optra 2 weeks ago. ODO at 1000. the FC is terrible @ about 7km/L. i am not a heavy footer. traffic has been moderate. Actually, the battery die and has to be replaced after 2 days. on top of that, the suspension at the back was noisy. The mechanic inspected the car and discovered that the nuts wasnot been tighten properly. On top of that, the petrol sensor has to be replaced because it wan't functioned properly. all these happened in the last 2 weeks. I think the engine has not run in. however, even after the engine has ran in, the FC i think will decrease a little only which still made the car not a good buy. not very happy with the car. bad choice. not a happy person.
