Petrol Drinking car (Average Mileage 5-6KM/L)

The buying experience was good. The only mistake I did, never checked the mileage of the car. I believed the sales person who told me the average mileage is 14-17km/L. The Jeep team is not ready to accept the mileage issues. I have sent several mails to the entire Jeep team and there were no reply and solution. I am getting an average mileage of 5-6KM/L after driving 2500km with different conditions. My humble request to all customers who are planning to buy Jeep compass, please check the mileage on different conditions (traffic /non traffic etc.) to get the real mileage. Do not believe the sales person who just want to sell the car.
