Hi Trek,
Thanks for your kind reply.I went to the service station for changing the oil and filter.But the technician said that the oil is too black.so I need to do the flushing.he did flushing,changed filter,added semi synthetic oil.he told me if it was synthetic oil you need to change the oil only at 10k kms and if its semi synthetic its at 5k km.Later on he advised to use fuel injector cleaner which is required for better mileage it seems.so all done in this service.he said in next 5k km i need to do only oil change..filter is required to change only at 10k km it seems.
Hi Technician..thanks for your reply..No..i havent considered doing it myself..i have done the servicing from an Adnoc service station yesterday.As the oil was really black,i had to do the flushing.They were doing flushing with an OBS machine.Also the technician over there recommended fuel injector cleaner and did that as well..the oil was semi synthetic oil..so all in all even though it costed alot,engine is completely flushed ,oil is changed and the fuel injector cleaner was poured into the petrol tank.i hope this will help for a smooth run and a breakdown at a later stage.
