Hi guys thanks again for the hint that I should check dip stick first and that is T4. My car has just done 100000 KM and vendor recommends that the OIL must be changed at this stage.
But my car is very smooth and I am not observing any problem so I have decided to go another 10000-15000 KM because it is going to be very expensive only service charges are 2000 + the cost of oil and filter change.
